loiigiT iuid ihiiiiiiT lliMii the liifenil diics. Tlu' I liomcical segments bear one row 

 each. The epiiiu'niin of the luesothorax bears five bristles, one being situated 

 in front and ioiir behind. The epiinernm of the metathorax bears two rows of 

 bristles, tlie first row consisting of four to seven, and the second of six to eight. 

 The threi' lowest iiristles of the secon<l row stand closer together than the others. 



Abdomen. — Tliere is one row of bristles on the alidoininal tergites, the first 

 tergite bearing some hairs in addition. The stigma is very large, and stands in 

 tlie (J above the first bristle, in the ? above the second, except segments 2 and 7, 

 where the stigma is situated as in the 6. The seventii abdominal tergite bears 

 one long apical bristle accompanied bj- two very short ones. The sternites of 

 segments 2 to bear in the S one bristle, which is sometimes absent from the 

 first two sternites. On the sternites of segments 3 and 6 there is one short stont 

 bristle more than halfway up to the tergifes. On the sternite of the seventii 

 segment there is a third bristle in between. In the ? the first tno sternites have 

 one or no liristle, while the others have from four to seven. 



Legs.— The hairs of the forecoxa are short except those at the hinder edge. 

 There is a coml) of six or nine spine-like bristles on the hindcoxa, and at the ajiex 

 on the hinder side of the same coxa there are three stout bristles. The hindfemnr 

 is ventrally almost evenly rounded from base to apex, being more convex ventrally 

 than dorsally. There is a subventral row of bristles on the outer surface of the 

 hindfemnr, and a snblateral row on the inner surface. All the tibiae have a few 

 liairs at the ventral edge, and the interspace between the short subapical pair of 

 dorsal bristles and the preceding one is very wide. The dorsal bristles of the 

 hindtibia are short and rather slender. Of the seven pairs the third is miiuite, 

 and the first and sixth are much shorter than the tibia is broad. The longest 

 apical dorsal bristle reaches to the tip of the first tarsal segment. There is one 

 row of hairs on tlie outerside of the hindtibia, besides the ventral hairs. The tarsi 

 are very sh'iider ; the fourth segment is short and cup-shaped. The longest apical 

 bristle of tlie second hiiidtarsal segment reaches beyond the middle of the fil'tli. 

 The raeasnrfiuents of the tarsi are : - 



Modified Segments. — The clasjiing organs of the S somewhat resemble those 

 of /'ii/i'.r ^^/>/^^. There are three processes (PI. VIU. fig. 19), the uppermost being 

 tlie longest and the ventral one the broadest. The ninth sternite (PI. VIII. fig. 2(1) 

 is beset with very smnll bristles at and near the ajiex. 



The eighth tergite of the ? (PI. IX. fig. 24) bears a row of bristles near the 

 edge and two short bristles on the side. The stigma is large. The segment is 

 completely divided on the back. 



Length : d, 4-2 mm. ; ¥, S2 mm.
