Ent, page 468. 



582. — Nyctozoilus Mastersii. n. sp. 

 Length 9 lines. 

 Convex, oval, black, opaque, and squalid. Head coarsely 

 punctate, subconvex, and deeply impressed on the median line, 

 with the clypeus on a lower plane than the posterior jjortion of 

 the head. Thorax transverse, not very deeply emarginate in 

 front, and nearly truncate behind, with the lateral margins 

 moderately broad, thick, and reflexed, the posterior angles slightly 

 constricted on the sides and pointed backwards, and the middle 

 of the disk vermiculate. Elytra much broader than the thorax, 

 not longer than the width, broadly rounded at the humeral 

 angles and the apex, and broadest in the middle, with the suture 

 and three irregular lines on each elytron slightly but distinctly 

 elevated, and the intervals irregularly and largely reticulate, and 

 subfoveate. Under surface less opaque and squalid, and substri- 

 olate, 



583. — Ntctozoilos elongatulus. n. sp. 

 Length 8 lines. 

 Of a more elongate and less convex form than the last species. 

 Head and thorax densely punctate, the former depressed in the 

 middle and in front, the latter rather longer than the width, 

 with thick reflexed lateral margins and prominent angles. The 

 sculpture of the elytra is the same as in N. Mastersii, but much 

 more distinctly and regularly reticulate. The head is rather 

 sharply angled in front of the eyes, and the clypeus is very 

 slightly emarginate. 



584. — Hypaulax Gayndahensis. n. sp. 

 Length 10 lines. 

 This species only differs from H. ovalis of Bates in having 

 the striae on the elytra very small, and the punctures very 

 largfc.
