I I 



dirty white, abdominal segments dark brown with dirty white edges producing 

 a banded appearance, which becomes obsolete on the last segments ; pile 

 short, appressed, grayish, becoming longer toward anal segments ; venter 

 dirty white, densely pilose on sides, each segment with long dark pile in 

 front, becoming light yellow behind ; legs dark, pile yellowish and of vary- 

 ing lengths ; tibia of hind legs with a circlet of short spines at apex ; first 

 joint of tarsus slightly shorter than second ; empodium and neuration of 

 wings as in C. specularis. 



Coloration of male darker throughout than in female ; antennal joints 

 1 1-14 inclusive equalling in length the remaining joints ; first joint globose, 

 enlarged ; joints 2-10 depressed globose, graduating in size toward apex 

 and becoming somewhat oblique ; joint n much elongated, nearly twice 

 the length of any succeeding joint ; joints 12-14 subequal, apical one 

 slightly larger and more oval-oblong. Pile, plumosity, sense organs, and 

 neuration of wings as in C. specidaris. Last four segments of abdomen 

 without the whitish edges, blackish, shining, pile denser and longer, with-

FIG. 6. A, characteristic dorsal bristles of each of the five species above described ; 

 r, anal segment of the pupa of C. specularis ; s, palpus of female of C. brumalis ; t, 

 palpus of female of C. texanns. 



Larva: Length 5 to 5.5 mm. ; dirty white ; head with two semihya ine 

 bristles ; one in front and the other behind the typical head spine ; chseto- 

 taxy for lateral half of body as follows : three longitudinal rows of barbel- 

 late bristles ; dorsal bristles hyaline, clavate, minutely tuberculate with 

 segments 5-10 joined at base by a straight black line ; dorso-lateral row of 

 double tubercles, the anterior limbs of which are tipped with curved, semi- 

 hyaline, broad bristles ; those on posterior limbs short and black ; lateral 

 row of bristles sparsely barbellate, black at base graduating to hyaline at 

 apex ; under the above there are several smaller and subventrally placed 

 simple bristles on each segment ; anal segment with an extra pair of 

 dorsal bristles behind the regular ones. Legs as in C. brmnalis. 



Pupa : 2.5 mm. long, whitish translucent, thorax armed on either side 

 with five yelTowish hyaline barbellate spines, the frontal one small with 

 mucronate tip just above and near the base of the antenna. The others 

 on the thoracic dorsum at the corners of a rhomboid ; the anterior spine
