Annual report . of the male prohibit its asso-ciation with Lasioptera, despite the numerous scales occurring uponboth wings and body. This species is easily distinguished by the11 and 10 segments of the male and female respectively, in con- REPORT OF THE STATE ENTOMOLOGIST I913 I9I nection with the strongly curved third vein. The adults rearedMay 7 and 8th, 1907 are very erratic in behavior, flying con-tinuously perhaps for 10 minutes and then refusing to take pale salmon larvae were found in early May, under a hard,black, carbonaceous fungus overgrowing a decayed oak stump. Thelarvae were in cells and frequently folded so that the two extrem-ities were approximate. Larva. Length 3 mm, slender, color pale salmon. Head ratherslender, with long, chitinous processes at the posterior lateral uniarticulate, the segment with a length four times itsdiameter. Anterior margin of the first thoracic segment chitinizedand supporting the subquadrate, slightly bidentate, chitinous process. Fig. 21 Lasiopteryx flavotibialis, ventral aspect of larval head (enlarged, original) resembling a small breastbone, from the base of which arises apair of long, diverging, chitinous prongs, all extending posteriorly(fig. 21) ; breastbone well developed, bidentate, the shaft long,slender. Skin nearly smooth. Posterior extremity broadly rounded,the median apical portion thickly set with short, stout spines. Male. Length mm. Antennae nearly as long as the body,thickly haired, fuscous yellowish; 11 segments, the fifth with astem three-quarters the length of the basal enlargement, which lat-ter has a length one-quarter greater than its diameter; terminal seg-ment with the basal portion greatly produced, nearly one-halflonger than that of the preceding, the distal part short, thicklysetose. Palpi; fuscous yellowish, the first segment short, stout,subquadrate, the second one-half longer, the third about twice thelength of the second, more slender, the fourth a little lon
