middle of the dorsal edge four rather long naked bristles of different lengths origin- 
ate; distally four other medial bristles, the anterior one, about the same length 
as the end-joint, conical and distally hirsute; the other three of them of ordinary 
type with short fine secondary hairs, the two anterior of about the length of this 
joint, the third a little shorter; posteriorly, somewhat laterally, this joint has two 
distal bristles, one of moderate length and of the type of the three last-mentioned 
bristles, the other almost quite rudimentary. The end-joint distally armed with six 
bristles, all pectinated, four of them are rather long and strong; the two others,

situated between the two posterior of the last-mentioned, considerably weaker and 
shorter. Laterally the palp is almost perfectly naked. Medial side: Second endo- 
podit joint has dorsally, a little behind the middle, a series of about five to six long 
and rather stiff hairs and from the posterior of these hairs another series of similar 
hairs with a trend to the postero-proximal corner of the joint; postero-distally on 
this joint as well as on the end-joint there are considerably shorter stiff scattered 
hairs. 
Maxilla: The three masticatory processes strong. The first and second of 
them armed with numerous uniform naked bristles, the first with about 13, the 
second with about 9; proximo-ventrally to the first process originate two bristles
