436 GEOLOGICAL SURVEY OF THE TEREITOEIES. 



miicli the appearance of a short, bhmt ovipositor. Legs more than me- 

 dium length ; anterior and middle pair slender. Anterior femora ser- 

 rated, inner carina one-spined, outer carina unarmed; middle femora 

 ^vith each carina minutely serrated and three-spined, and a spine on the 

 inside at the apex 5 posterior femora deeply channeled beneath, each 

 carina minutely serrated but not spined, passing the abdomen about one- 

 half their length. Anterior tibise have the posterior margins minutely 

 serrated, three spines on each, opposite ; middle tibiae with two spines 

 above, lower margins serrated, three spines on each, opposite ; posterior 

 tibise have the posterior margins serrated, four spines on each, opposite ; 

 four teeth of the serrature between the spines. Anterior coxse mucro- 

 nate on the exterior angle. 



Color, (dry, not alcoholic.) — Face pale yellow ; upper portions of the 

 head tawny. The entire dorsum pale castaneous, with somewhat darker 

 bands on the posterior margin of each segment, scarcely distinguishable. 

 A slight median yellow line on the thorax. Legs dull yellow, the pos- 

 terior pair darkest; spines yellow, not tipped with black; eyes black; 

 antennss fulvous. 



Dimensions. — Length, .70 inch; posterior femora, .5 inch ;■ posterior 

 tibiae, .5 inch. California. Presented by Mr. Taylor. 



This may possibly be the male of Dr. Scudder's C. Calif or nianus, but 

 ' the great difference in the length of the posterior femora would seem to 

 forbid this conclusion, although the color and absence of spines on the 

 posterior femora indicate a similarity. ]My specimen is evidently much 

 larger than the one he describes. This species appears to form a con- 

 necting link between CeuiliopMliis and UdeopsyJla, the head and thorax 

 having a strong resemblance to the latter genus. 



C. imcificiis, nov. sp. 



Male. — Golden yellow, dotted and minutely mottled with fuscous; pos- 

 terior femora with one large serrated si)ine on each carina; middle tibiae 

 spined above. 



Tubercle of the vertex prominent, pointed. Ultimate joint of the 

 maxillary palpi nnusually long, bent, and somewhat angled behind near 

 the base. Circi rather large, acuminate. Tip of the last ventral seg- 

 ment notched, and furnished on the outside of each lobe with a short 

 fusiform appendage. Anterior femora one-spiued, not serrated; middle 

 femora one or two spined, not serrated. Posterior femora much enlarged 

 for the basal three-fourths, suddenly contracted beneath near the apex; 

 a broad and tolerably deep sulcus beneath ; each margin minutely 

 serrated part of its length and furnished with one strong and very 

 broad spine. Each of these spines is serrated on the anterior margin; 

 the one on the interior margin is the largest and stands farthest from 

 the apex; between these spines and the apex the margins curve 

 upward, forming a kind of circular notch, and corresponding to this is 

 an enlargement or swelling of the front of the posterior tibise near the 

 base. The posterior femora are scabrous on the disk and upper edge. 

 The middle tibise, in addition to the usual spines below, are furnished 

 on the upper face with four spines, two in a row ; posterior tibiae ser- 

 rated, four spines on each posterior margin, opposite. 



Color, (dry, but not alcoholic.) — Ground color of the dorsal portions 

 golden yellow; of ventral surface and legs, a honey yellow; the face 

 mottled with fuscous, forming three irregular spots, one beneath each 

 eye and one in front; vertex and tubercle' black; cranium with a few 

 slender black lines, mostly longitudinal. The entire dorsum sprinkled 

 over with small irregular fuscous dots, giving it a mossy appearance.
