der of face ferruginous. Antennae and legs also ferruginous, 

 excepting the two proximal joints, which are darker, more 

 brownish or olivaceous. 



Sulcus of head interrupted in the interocular region. Cly- 

 peal foveolae 24-2. Antennae clavate ; sensory cones numer- 

 ous. Facets of eyes flat, often obscure ; eye subtriangular, with 

 apex ectad ; ocelli about 28 in five transverse series ; c. g., 7, 7, 

 6, 5, 3 ; the ectal ocelli of upper series much the largest, the 

 others decreasing mesad and centrad. Eyes nearly three 

 times their greatest diameter apart. 



Collum widely rounded on each side below, the second ter- 

 gite extending considerably below its ends ; not margined, stri- 

 ate or distinctly punctate, being smooth and shining. 



In a typical segment from the middle region of the body 

 the suture is fine but complete, angled at level of pore which 

 it touches, the suture lying in a furrow which is vague dor- 

 sally but becomes distinct below level of pore. No secondary 

 furrow'. A little in front of the suture a shallow furrow, 

 which is often irregularly developed and may be evident only 

 across dorsum above level of pores, its lower end on each side 

 often curving cephaloventrad. Covered portion of pr~>.7onite 

 with the usual transverse sulcus across dorsum just caudad 

 of this striolate region. Metazonites with deep longitudinal 

 striae only below, the non-striate region between pore and the 

 striae twice as wide as the striate region. Under the lens this 

 region between striae and pore shows weaker short impressed 

 lines which are in part branched and scattered punctae, this 

 same sculpture continuing in a band caudad of the suture up 

 some distance above pore on each side, the metazonite other- 

 wise wholly smooth. 



Scobina distinct to segment 22 or 23, at which they cease 

 abruptly.
