SOC. 19 Of the nine pairs of stigmata the first is situated near the an- terior margin of the mesothoracic fold, the other eight pairs are on the pleurites [see Bulletin No. 2 page 11] of the first eight ab- dominal segments. Ventral part of ninth segment consists of two slightly protruding fleshy propellers. Larval State of Eleodes Gigantea. Head convex above, gular region concave ; all the mouth-parts like Tenebrio ; antennae differing by the stouter 2d and 3d joint. Legs, thoracal and abdominal segments
. Bulletin of the Brooklyn Entomological Society. Insects. BULLETIN OF THE BROOKLYN EOT. SOC. 19 Of the nine pairs of stigmata the first is situated near the an- terior margin of the mesothoracic fold, the other eight pairs are on the pleurites [see Bulletin No. 2 page 11] of the first eight ab- dominal segments. Ventral part of ninth segment consists of two slightly protruding fleshy propellers. Larval State of Eleodes Gigantea. Head convex above, gular region concave ; all the mouth-parts like Tenebrio ; antennae differing by the stouter 2d and 3d joint. Legs, thoracal and abdominal segments with no perceptible difference. Pygi- dium with 18 lateral penicilli and terminal ob- tuse tip, sparsely fimbriate. Color of small in- dividuals (6 mm.) entirely white. No trace of ocelli or even dark pigment spots on the oph- thalmic region. The small larvae from which the drawing is made have the abdominal seg- ment nearly all flat, gradually after several ex- uviations acquiring the typical string or wire- shape and also darker color. The penicilli are a direct prolongation from the hypoderm,pierc- Fig. 4. ing the chitinized cuticula. Fig .4. A, Larva of Eleodes gigantea. E, anterior leg, C, gula, men- tum, ligula and labial palpi, D, antenna. B, middle and posterior leg. F, pygidium, acetic ac. prep., powerfully magnified, left side omitted. G, three last segments (lateral view), anus, pygidium and propellers. Fig. 5. A. pygidium of Eleodes dentipes [7 mm. long larva], magnified; j about 4 weeks old. b, anterior leg, magnified. Coxa and trochanter each with two blunt teeth, trochan- ter with two penicilli near tip, and femur with four Ipenicillia at middle. Simple claw with rudimentary F'g- 5 median fissure at tip and one penicillus at middle. Larval State of Eleod. Dentipes. Head and mouth-parts, antennae, middle and posterior legs alike as in EL gigantea. It differs by the pygidium having but ten penicilli, the two terminal are slightly longer and run parallel over termi
