278 MR. R. E. TURNER ON THE [Feb. 15, 



ferruginous, Wings hyaline, faintly clouded near the apex, 

 nervures black, stigma fusco-ferruginous. 



Length 11 mm. 



5 . Head rectangular, slightly rounded at the posterior angles, 

 a little broader than long, sparsely but rather coarsely punctured, 

 with a strong, longitudinal, frontal sulcus. Pronotum a little 

 narrower than the head, broadly emarginate anteriorly, nearly 

 half as broad again as long, with a well-marked median carina., 

 depressed and slightly concave on each side of the carina, minutely 

 punctured. Median segment as long as the scutellum, broadened 

 from the base and obliquely truncate posteriorly, closely punctured. 

 Abdomen much broader than the thorax, the first segment trun- 

 cate at the base, with a transverse carina above the truncation, 

 the dorsal surface very broadly depressed to the apex, with a 

 raised curved mark on each side ; the second segment with two 

 or three transverse carinas near the base, the apical margin 

 very feebly raised ; segments 3 and 4 broadly depressed at the 

 apex, with a raised, curved, punctured mark on each side ; fifth 

 segment sparsely punctured. Ventral surface closely and rather 

 coarsely punctured on the fifth segment as well as on the rest. 

 Pygidium very narrow, deflexed and lanceolate, very narrowly 

 rounded at the apex. 



Fuscous ; the apical margins of the abdominal segments broadly 

 pale testaceous ; the carinas on the second segment and the 

 pygidium fusco-ferruginous. 



Length 6 mm.

S . Clypeus advanced and not very narrowly truncate at the 

 apex, coarsely but shallowly punctured, convex. Antennas as 

 long as the thorax and median segment combined, a little 

 slenderer at the apex than at the base, the apical joints very 

 feebly arcuate beneath ; the third joint of the flagellum as long- 

 as the first and second combined ; inserted a little further from 

 each other than from the eyes, the interantennal carinas oblique. 

 Head very closely punctured, with short grey pubescence on the 

 front, a little broader than the pronotum. Thorax very closely 

 punctured, more sparsely on the pronotum. Median segment 

 much shorter than the mesonotum, twice as broad as long, 

 scarcely narrowed to the apex, more finely punctured than the 

 mesonotum ; a large, shallow, smooth depression on each side at 

 the base. Abdomen shining, sparsely punctured, the sides almost 

 parallel, tapering very slightly at the extremities; the first seg- 

 ment with a sulcus from the base to beyond the middle ; segments 

 2 -5 slightly constricted at the base ; the seventh dorsal segment 

 rugose, broad at the apex and with the apical margin raised to 

 form a low carina. Ventral segments 2-5 subtuberculate at the
