Yery similar in colour to tenuinodis. Pilosity and pubescence as in 

 that species, but the legs with a denser pilosity. Head dull, except the 

 posterior fourth, which is slightly shining. Thorax and abdomen dull, 

 the pronotum nitidulous in front. Head longitudinally striate 

 between and behind the frontal carinae, longitudinally reticulate, 

 rugose at the sides, the spaces between the striae dull and finely 

 reticulate. The striae extend further backwards than in 

 tenuinodis. The posterior fourth of the head microscopically rugulose, 

 with a few large and shallow punctures. Mandibles smooth and 

 shining, finely and sparsely punctured. Pronotum with a few feeble 

 transverse rugae, the rest of the thorax and the petiole reticulate, 

 almost transversely striate on the declivity of the epinotum. Abdomen 

 alutaceous. 



Head resembling that of tenuinodis, but more convex and higher, 

 widest behind the middle, narrower in front than behind, the occipital 

 lobes much more rounded and obtuse, the occipital emarginati on much 

 shallower and arcuate, not angular at the apex. Occipi to- frontal 

 sulcus also shallower than in tenuinodis. Clypeus sharply carinate in 

 the middle. Posterior lateral angles of the pronotum very obtuse, 

 small, and not projecting laterally. Pro-mesonotal suture more clearly 

 defined than in tenuinodis. Mesonotum with a transverse impression 

 in front of the scutellar portion, the latter fairly well defined. Dorsum 

 of epinotum almost horizontal, as long as wide between the teeth. The 

 latter are slightly divergent, and their front edge is continued as a 

 raised line forwards, margining the dorsum. The declivity is very 

 oblique and as long as the dorsum. First joint of the petiole 

 like that of tenuinodis, but the dorsal edge is not emarginate. 

 Second joint almost twice as wide as the first, nearly one-fourth wider 

 than long, widest in the middle, the sides obtusely angulated in the 

 middle, not convex as in tenuinodis. 



5 . 2 "3-3 mm. Reddish-yellow, the head darker behind, abdomen 

 brown, paler at the base. Legs and antennae dark ochreous. The 

 clypeus, middle of the head longitudinally, the disc of the mesonotum 

 and the abdomen smooth and shining, the rest of the body dull or 

 only nitidulous. Pubescence and pilosity as in punctulata $ . Sides 

 of the head finely reticulate-punctate and with a few longitudinal 

 striae, which do not extend far behind the eyes. Thorax reticulate- 

 punctate, more strongly so than in punctulata. Petiole slightly 

 shining. Head oval, widest in the middle, the anterior half as wide 

 as the posterior (in punctulata and tenuinodis wider behind than in 

 front), the sides convex. Eyes very convex, placed at about the 

 middle of the sides. Frontal carinae short, parallel ; frontal area
