finely punctured ; elytra regularly punctate-striate, the interstices 

 very sparingly puuetured. 



Length 4 millim. 



Of broadly ovate shape ; the head broad, very sparingly and finely 

 punctured, with an oblique groove in front of the eyes, the latter 

 very large ; clypeus broad and thickened ; antennae not extending to 

 the middle of the elytra, fulvous, the second joint slightly shorter 

 than the third but thicker, terminal joints elongate ; thoi-ax trans- 

 verse, nearly three times broader than long, the sides nearly 

 straight, the anterior angles obliquely truncate with a small notch 

 at each side, the posterior margin with a perpendicular short 

 groove at each side, the surface closely and finely punctured 

 throughout ; elytra wider at the base than the thorax, widened 

 towards the middle, the disc rather regularly and distinctly 

 punctate-striate, the striae widely placed, the interstices with a 

 few fine punctures here and there, elytral epipleurae very broad ; 

 legs short and robust, presternum longer than broad ; anterior 

 coxal cavities closed. 



Hah. Cameroons. 



From other similarly coloured species the present insect is 

 distinguished by the broadly ovate shape and the punctate-striate 

 elytra. I received two specimens from Dr. Kraatz of Berlin. 



NlSOTEA COSTATIPENlvriS, sp. n. 



Pale fulvous ; the thorax finely and closely punctured, with deep 

 basal perpendicular grooves ; elytra strongly punctate-striate, the 

 interstices longitudinally costate and finely punctured. 



Length 4 millim. 



Nearly parallel in shape ; the head impunctate, obliquely grooved 

 between the eyes ; the clypeus broad, widely separating the antennae 

 at the base, labrum fulvous ; antennae nearly extending to the 

 middle of the elytra, fulvous, the third and fourth joints equal ; 

 thorax strongly transverse, the sides slightly rounded before the 

 iT)iddle, the anterior angles obliquely truncate, the basal margin 

 with a deep and long perpendicular groove at each side, nearly ex- 

 tending to the middle, the surface finely and closely punctured ; 

 elytra strongly punctate-stj-iate, the punctures closely placed, the 

 interstices convex and finely punctured ; underside and legs 

 coloured like the upper surface. 



Hah. Cameroons. 



Although I have received only a single, apparently female, speci- 

 men from Dr. Kraatz, I think the species varies sufficiently from 

 any of its allies to be of certain recognition ; the thoracic basal 

 grooves are more than usually large and deep, and the elytral inter- 

 stices differ from those of every other species in being longitu- 

 dinally costate, peculiar perhaps to the female only. 



NlSOTKA UNlt'ASCIATA, Sp. n. 



Fulvous, the terminal joints of the antennae fuscous ; thorax
