posteriorly. Alxlonii'ii very spnrMoly atul finely punctured ; 

 the tirdt segment with the apical margin slightly raised, with 

 a narrow transverse groove before it ; second segment with 

 tiiree strong transverse carina) including the raised apical 

 margin, and another very low carina just before the apex. 

 Pygidium rather narrow, slightly arched at the base, obliquely 

 truncate posteriorly, the surface of the truncation constricted 

 near the base, narrow before the constriction, the portion 

 beyond the constriction ovate with slightly raised margins. 

 Fifth ventral segment sparsely and not coarsely punctured. 



Fuscou.'S, paler on the thorax ; head ferruginous ; legs 

 testaceous brown, a spot on each side of the two first abdo- 

 minal segments obscure ochreous. 



Jjength 8 mm.

^ . Clypeus narrowly produced and triangularly emarginate 

 at the apex, very sliglitly convex, shaliowly punctured, with 

 sparse white pubescence. Head very finely and closely 

 punctured, with a longitudinal frontal sulcus, the inter- 

 antcnnal prominence emarginate at the apex, not strongly 

 developed, the front and sides of tiie head thinly covered with 

 white pubescence. Antennoe inserted as near to each other 

 as to the eyes, shorter than the thorax and median segment 

 combined, filiform, the apical joints scarcely arcuate. Thorax 

 and median segment shining, very finely punctured, more 

 closely on the sides of the mesonotum and base of the median 

 segment than elsewhere, the pronotum almost smooth. 

 Scufellum rather short, very broadly rounded posteriorly; 

 median segment broader than long, not convex, obliquely 

 sloped from near the base. Abdomen elongate, tapering a 

 little at the extremities, longer than the head, thorax, and 

 median segment combined, segments 2-5 slightly constricted 

 at the base. Hypopygiuin projecting beyond the dorsal 

 segment, narrow, gradually narrowed to the blunt apex. The 

 ventral segments of the abdomen are rather strongly punc- 

 tured ; the dorsal segments shining, very sparsely and finely 

 punctured. The third abscissa of the radius is nearly twice 

 as long as the second ; the second recurrent ncrvure is 

 received just beyond two-fifths from the base of the third 

 cubital cell. 



Black ; the mandibles (except at the apex), clypeus, inner 

 orbits of the eyes narrowly, two minute spots between the 

 antennje, a transverse line on each side at the posterior angles
