these is a smaller tooth, while from this point to the base the edge is 

 thinner and rather finely serrate. Maxillae with the inner piece broad, 

 truncate at tip, inner angle acute; along the free end is a number of pieces 

 about five; the outer piece is four-jointed, the three basal joints heavy, 

 but rapidly decreasing in thickness, the fourth joint more slender and 

 longer. Mentum short and broad, the palpi two-jointed, very thick, sec- 

 ond joint longer and more slender than the first and armed at tip with a 

 few small spines; ligula papilliform, furnished with two setae. Prothorax 

 transversely subelliptical, disc rugose, with a broad, shallow, transverse 

 impression, bristly, posterior margin sinuate, sides rounded. Meso- and 

 metathorax shorter. Abdomen of nine subequal segments, each with a 

 double transverse row of bristles extending around the entire circumfer- 

 ence. The nmth segment bears on the dorsal surface, between these 

 TOWS, two short, erect, slightly recurved processes; there is also a tenth 

 false segment, used as a prop-leg in walking. Spiracles dorso-lateral, in 

 nine pairs of which the first is situated near the anterior mesothoracic 

 angles, the remainder in much the same relation to segments one to eight 

 of the abdomen; they are slightly exserted and brownish in color. Legs 

 short, rather scantily bristled, the coxae conical, trochanters distinct from 

 and shorter than the femora, which are thicker near the tip, tibiae again 

 shorter and tapering to apex, claws simple and only moderately curved. 



These larvae were taken at Bayfield, Wis. , about the middle 

 of July. They lived in a fleshy fungus found growing on dead 

 wood, and went under ground to pupate, remaining in this con- 

 dition eight days. The pupa is 5 mm. in length, and most ex- 

 tremely bristly on the thorax, wing-pads and abdomen, the tip 

 of the last bearing a stout spine. 



Carpophilus niger Say, fig. 2. Color of larva, in life, nearly white, head 

 chestnut, in spirits the general color becomes yellowish. Form elongate, 

 flattened, wider near the end of the abdomen. Length of alcoholic 

 specimen 6 mm. 



Head rather large, broader than long, narrower anteriorly, sides rounded, 

 front with a long and broad prolongation between the antennae, this lobe 

 being rounded at tip. Labrum small, distinct, in the form of a triangle 

 with the base excavated and the apex rounded. Antennae four-jointed, 

 the first joint extremely short and thick, the remainder successively more 

 slender, the third joint longest. This joint also bears a small articulated 

 appendage besides being the support of the fourth member; only a few 

 short bristles can be seen. Mandibles nearly triangular in outline, the tip 

 curved, the inner margin armed with about nine sharp teeth, of which tin- 

 upper ones are longest and more curved. These teeth are again armed 

 internally with spines forming a rather complicated structure. At the 

 inner base of the mandible is seen an elliptical area which is distinctly 

 transversely punctate-striate. Maxilla- \\ith tin- (-HUT lobe armed at tip 

 with an extremely bristly scutiform sulitriangiilar pkce, imnudiaU-h \ re-
