hirsute, the distal much more slender and densely pubescent. Head- 

 plate cordate, hirsute, without sulci ; basal plate not visible. Maxil- 

 lary sternite wide, simple, with toothless but bristly anterior margin ; 

 maxillary feet bristly, inner margin not furnished with teeth ; claw 

 long and gently curved. 



Tergites scantily hairy and sparsely punctured ; first without 

 sulci and slightly overlapping the head-plate in front ; second with 

 two shallow sulci ; the rest, with the exception of the last, bearing four 

 sulci, two median, parallel, complete, and on each side one which, 

 starting anteriorly near the median sulcus of its side, curves out- 

 wards and terminates on the surface of the tergite in the anterior 

 region of the body, but reaches, or nearly reaches, the hinder margin 

 of the plate in the posterior region of the body ; lateral margins not

raised. Sternites : each, the first excepted, furnished with a median 

 longitudinal sulcus, aud most of them with a median transverse 

 sulcus, which cutting the other at right angles makes the form of a 

 cross. The distinctness of this latter sulcus is variable, and it 

 almost disappears in the posterior region of the body. Anal segment : 

 tergite with parallel lateral margins and angularly produced poste- 

 rior margin ; anterior portion of pleurite furnished with large, not 

 close-set pores ; posterior portion without pores ; posterior margins 

 slightly convex and bristly, obtuse below ; sternite with a median 

 anterior abbreviated sulcus, slightly curved lateral margins and 

 convex posterior margin. Legs (all that remain) remarkably hirsute, 

 but none of the segments spiny or denticulated. 



Length about 27, of antennse 5| millim.
