The posterior half of the elytra is darker than the anterior but I am not at all sure that this is due to any difference in color in the living insect, it seems more likely the result of scaling off of a portion of the metamorphosed chitin when the stone was split.

Trypherus aboriginalis Wickham. Two specimens, one with counterpart, No. 2,503-2,505 M. C. Z. No. 8,586, 8,499 and 8,651 S. H. Scudder Coll.). They show no important characters not brought out in the original description. MALACHIIDAE. Collops priscus, sp. nov. Plate 5, fig. 3-4. Form, in life, apparently similar to that of the recent C. bipundatus but as preserved the abdomen is greatly distended, presumably by maceration. Head with rather indistinct outline, sculpture not dis- cernible, antennae short, stout, first joint elongate, second much longer and distorted by the production of the inner apical angle, the third, fourth, fifth, sixth, and seventh, subtriangular, moderately serrate, eighth damaged, remainder not definable. Prothorax about as long as the head, no defined sculpture. Elytron nearly smooth but with a sparse covering of rather long black hairs. Legs slender. Length, as preserved, mm.; of elytron, mm. Described from one specimen with counterpart. Type.—No. 2,506, 2,507 M. C. Z. Florissant, Col. (No. 8,140 and 9,307 S. H. Scudder Coll.). The form, vestiture, antennae, and abdominal segmentation all point to the above generic reference. Measured from the front ot the head to the elytral apex, this insect about equals in size the living North American C. hirtcllus which occurs from New Mexico to Nev. Washington, and the Please note that these images are ext
