angle of one side to that of the other; the posterior border straight 

 between these same angles. The second tergite with its keel below 

 the level of the margin of the first and the keel of the third, anteriorly 

 and posteriorly produced. The keels of the third and fourth with rounded 

 anterior and acute and produced posterior angles. The keels of the 

 rest above the middle of the sides, horizontal , complete , with rounded 

 anterior angle, the posterior angle acute and produced beyond the 

 hinder border of the tergite. The dorsal surface smooth, the sulcus 

 deep and complete, running from keel to keel, beginning on the 

 fourth , but not so strong on this somite as on the rest. Each somite , 

 except the anterior, marked with a fainter longitudinal sulcus. The 

 transverse sulcus and the anterior furrow finely sculptured. A row of 

 piliferous pores along the posterior border and also a similar row in front 

 of the transverse sulcus. Lateral surface exceedingly finely granular. 

 Inferior crest absent. Caudal process rather slender, but normally 

 formed. Anal sternite normally tuberculate. Sternal areas normal, not 

 spined. Legs normal with claws distinct. 



cf. Slenderer than the Q. The process on the sternum of the fifth 

 somite, thick, long, and bifid. The copulatory feet of normal length, 

 rather wide and flattened, terminating in two processes, the external 

 of which is sublaminate, more or less contorted , with a spiniform process 

 on the distal extremity of the external margin , constituting on sheath 

 or covering for the internal process, which is flagelliform.

Colour when mature a pinkish red, with the anterior segments 

 paler; antennae black; head chocolate brown; feet flavous; a fine 

 longitudinal fuscous line in the middle of the back.

 moderately long. 



First tergite convex , laterally depressed and sub-carinate , the lateral 

 portion in front convex and evenly continuous with the lightly 

 convex anterior border, behind also convex , but depressed or sinuate 

 at the base, the posterior border being straight and not sinuate. The 

 second tergite with its keel large , horizontal , anteriorly and posteriorly 

 produced, but more posteriorly than anteriorly; third and fourth with
