COLEOPTERA 



More rotundate than A. altulus ; may be at once identified by 

 the finely rugose elytra. 



Length, i^ lines ; breadth, nearly f. 

 Howick. Found on the ground. 



Obs. — The characters of Adolojnis (Sharp : Trans. Ent. Soc, 

 1884, Part IV., p. 478) are as follow: Corpus parvum, rotundato- 

 ovale, superne convexum. Antennae g-articulatae, clava elongata, 

 laxe articulata ; palpi niaxillares breves, articulis tribus ultimis 

 longitudine subaequalibus, articulo pseudo-basali crassiore, mentum 

 transversim quadratum, anterius late depressum. Prosternum in 

 medio longitudinaliter carinatum. Coxae intermediae distantes, 

 metasterno inter eas longius productum, cum processu triangulari 

 mesosterni sutura recta conjunctum, processu hoc ad latera mar- 

 ginato. Femora posteriora subtus glabra; abdomen densissime 

 subtilissime punctato-pubescens, segmento basali in medio carinato. 

 Tarsi posteriores parum elongati et parum crassi, articulo basali 

 brevi, secundo parum elongato sed quam praecedente evidenter 

 longiore. 



No. 150 should become Saphydnis oblongus. The genus was 

 published at p. 467 of the Trans. Ent. Soc. 1884, Part iv. 



Exydrus. 



Nov. gen. 



Agrees in most respects with Dr. Sharp's genus Hydrostygnus 

 (Trans. Ent. Soc, Part iv., p. 475), but differentiated by the 

 following characters : Lahrum small, obliquely excised on the left 

 side of the apex. Ej) is tome truncate in front. Eyes more pro- 

 minent and distinctly facetted. Middle of metasternum not pro- 

 minent and not more coarsely sculptured than elsewhere. Posterior 

 femora finely punctate and covered with obvious yellow hairs. 



The genus is instituted for Nos. 153 and 154, which become 

 Exydrus flavicornis and E. gibbosus. 



Cercyodes. 



Nov. gen. 



Antenna elongate, g-jointed ; basal joint long, cylindric ; second 

 nearly as stout as first, about half its length ; third as long as 

 second but much more slender ; joints 4-6 decrease in length ; club 

 compact, very large, tri-articulate. Maxillary palpi not elongate, 

 basal joint small, second moderately stout, the terminal longer than 

 third, narrowed towards and truncate at the extremity. Legs short 

 and stout, posterior femora nude ; anterior tibiae rounded and fringed 

 with short spines at the apex and there furnished with short straight 

 spurs, their lower and inner face excavated for the tarsi ; tarsi short, 

 posterior somewhat compressed, very sparsely pilose, basal joint very 

 short, 2-4 equal, fifth longest. 



Allied to Cercyon, anterior coxce less prominent ; prosternum 

 without a distinct process, merely gradually raised to the level of 

 the carinate middle portion ; cpiplenra narrow, and on the same 

 plane as the breast ; middle of metasternum a little elevated, nearly
