only. It is quite probable that the notes of M. Coquillett * really 

 apply to this species, and not to B. cinerea, which does not occur in 

 California. 



Steniolia sulfurea, sp. nov. 



$ . With the exception of the entirely black thorax, front, vertex, cheeks (ex- 

 cept orbits), small spots on the coxae and trochanters, first segment of abdomen on 

 its fore surface and a triangular mark above (which is sometimes merged into the black 

 anterior), the insect is bright sulphur yellow ; the flagellum dark above, yellowish on 

 basal half beneath, wings hyaline ; pubescence of head and thorax dense and grayish. 



Flagellum slender, acuminate, though shorter than in S. duplicata ; front long 

 and narrow, much more so than in the species mentioned ; legs robust ; second ventral 

 segment carinated on apical third, the carina extending to apical margin where it 

 projects in the form of a slight tooth ; seventh ventral segment medially at apex with 

 an emargination, in which rests a large bifurcated process forming part of the genitalia 

 and having one furcation much longer than the other. Length, 19-20 mm. 



Habitat : Shasta County, California. Two specimens collected by 

 the late Henry Edwards and forming part of the collection containing 

 the preceding specimens. It is not closely related to any described 

 species of Steniolia, and is quite remarkable in its coloration. 



NOTE ON THE LARVA OF PSAPHIDIA 

 THAXTERIANUS. 



By Harrison G. Dyar. 



Head luteous brown, dotted with whitish, a black patch on each 

 side of the clypeus with a brown shade on the angle of the lobe and 

 one extending upward on the posterior edge of the lobe, widening 

 above to suggest an elliptical pale enclosure on the side; width 3.3 

 mm. Body vinous brown, a little greenish tinted ; a series of large 

 subdorsal creamy white patches on joints 2 to 14, on the thorax cov- 

 ering the sides of the cervical shield setae ia to iib, on the abdomen 

 setffi i to iii (the patch somewhat trilobate) and whole of anal plate. 

 Tubercles and spiracles white ; setse normal, single, distinct, but fine, 

 pale ; thoracic ones well separated and all present. 



The handsome larva of this rare Noctuid occurred to me on the 

 white oak at Brookhaven, N. Y., in June. It was fully grown and
