Maxillary palpi not as long as the labial palpi. Labial palpi reach 

 to apex of anterior coxa, 5-jointed. Antennal groove in the male 

 reaches to top of head, in the female to within one-third. There are 

 3 bristles on the lower genal row, the middle of which is the smallest, 

 while the upper genal row is represented by 3 small bristles, extending 

 along the edge of the antennal groove. In the male the lowermost 

 bristle is frequently paired. There are several fine hairs above the 

 eye. The occiput contains the normal row of apical bristles, the 

 lowest of which is the largest. There is one bristle back of the middle 

 of the antennal groove and a number of fine hairs along the posterior 

 margin of the antennal groove. The antenna is 3-jointed, the first 

 joint contains a row of about 5 very short fine hairs, while the second 

 joint contains about 5 not as long as the third joint. 



Thorax. — The pronotum has one row of about 10 bristles, and a 

 ctenidium composed of about 16 or 18 spines. The mesonotum has 

 a posterior row of about 10 long bristles and there is an anterior row 

 of more numerous smaller ones. The metanotum has also a posterior 

 row of about 10 large bristles, with an anterior row of more numerous 

 smaller ones, while still anterior to this there are 5 or 6 still smaller 

 bristles. The metathorax contains 8 or 10 bristles which are small 

 anteriorly, larger posteriorly. On the sternum of the metathorax 

 there are 2 large bristles, while the episternum has 3 smaller ones. 

 On the epimerum are 2 bristles placed anteriorly and 3 or 4 posteriorly, 

 one of which is on the apical margin. 



Ahdomen. — The first stigma is nearly in line with those of the other 

 abdominal segments. There are two rows of bristles on the abdominal 

 tergites, a posterior of about 12 or 14 and an anterior of smaller, less 

 numerous bristles. The antipygidial bristles in the female are 3 in 

 number on each side, of which the middle is the longest, and the inner 

 one the smallest. The male has but 2 antipygidial bristles on each 

 side. The sternites from the third to the sixth have a single row of 

 about 10 bristles, while the seventh has about 12. The metanotum 

 has 2 teeth on each side, as have the first and second abdominal 

 tergites. The third and fourth abdominal tergites have 1 tooth on 

 each side. 



Legs. — The fore coxae are normally clothed. The fore femur has 

 on the outer side 11 or 12 fine bristles irregularly disposed, while on 

 the mid femur there is a row of about 3 to 5 bristles on the inner sur- 

 face. The hind coxa has no patch of spines on the inner side, while 

 on the inner surface of the hind femur there is a row of about 5 to 7 

 bristles. The spines on the posterior tibia are in pairs of six groups, 

 while on the outer surface there is a row of about 7 bristles. None 

 of the apical bristles of the tarsi are as long as the next succeeding 

 joint. The fifth tarsal joints on all the legs have 5 lateral spines.
