The head is very large, rounded below, and a little longer than the first three pergonal seg- 

 ments. The first three segments of the pjerwon are coalesced, the following are free. The 

 carpus of the first pair of per cwpo da is dilated and produced; the front side of the carpal 

 process is shorter than half the hind margin of the metacarpus. The carpus of the second 

 pair is produced; the front side of the carpal process is a little more than half as long as the 

 hind margin of the metacarpus. The metacarpus of the first and second pairs has a single 

 bristle on the front margin; the dactylus is moderately long. The third and fourth pairs arc 

 a little longer than the first and second; the carpus is not tumid, and without bristles: the
