108 Memoirs on ite Coleoptera 



the female, extremely flattened distally; prosternum broadly convex, with 

 two small deep foveae near the apex, separating the coxae by much more 

 than their own width, the large broad flat plate behind the coxae sinuous at 

 tip, with rounded angles; scutellum small, moderately free; fourth tarsal 

 joint and claws long and unusually developed. [Type 5. platyrhinus nov.] 



Sunilius 



Antennae medial in insertion 5 2 



52 — Scutellum flat, in close contact with the elytra; beak rather thick, separated 

 by a deep transverse sulcus; prosternum with a sharply defined and elongate- 

 oval, closed and punctured concavity, the coxae well separated; antennal 

 club small. [Type R. seriatirostris nov.] Reveniopsis 



Scutellum transverse, somewhat convex, free; beak and antennae somewhat as 

 in the preceding, the body very much larger in size; tibiae more or less 

 inflated in the male, the male, as a rule, with two short prosternal spines; 

 elytra strongly grooved. [Type M. convexa nov.] Macrorevena 



53 — Antennae subbasal in insertion, especially in the female, notably long and 

 slender, the two basal joints of the funicle much elongated; beak rather 

 slender; prosternum almost flat, the coxae rather widely separated; upper 

 surface sparsely punctulate throughout. [Type R. sexualis nov.]. . .Revena 



Antennae far behind the middle, moderately elongate, the second funicular joint 

 much shorter than the first, the beak subsimilar in the sexes and separated 

 by a rather deep sulcus; prosternum broad and flat, having two rapidly 

 pointed short erect plates in the male, the coxae separated by fully one-half 

 more than their width; body much smaller than in the preceding, about 

 as in Claudius, but not herissate, though having a few decumbent squamules. 

 [Type S. cuneipennis nov.] Selasella 



Antennae inserted barely behind the middle, much less elongate; beak less slender 

 and less elongate than in Revena, nearly straight, curving at base; prosternum 

 narrowly canaliculate, the coxae moderately separated; upper surface sparsely 

 herissate, the elytra strongly grooved; scutellum very small; body very 

 much smaller in size, more abbreviated and oval, and with relatively larger 

 prothorax. [Type C. cephalotes nov.] Clandius 



54 — Beak short and rather thick, compressed, separated by a coarse and deep, 

 transverse sulcus; antennae medial; prosternum flat, the coxae widely sepa- 

 rated; upper surface with strong but not dense punctures, the elytra deeply 

 grooved; scutellum moderate, subquadrate, not in very close contact with 

 the elytra. [Type P. planipectus nov.] Peclaviopsis 



Beak longer, very slender, thickened basally 55 



55 — Antennae submedial, rather short but slender and with small club; beak not 

 separated from the head by any kind of impression; prosternum canaliculate; 

 body oval; scutellum oblong, more or less free. [Type P. hispidicollis nov.] 



Peclavia 



Antennae very near the base of the beak and on a pronounced basal thickening, 

 rather long and well developed; prosternum impressed along the middle, 

 the coxae well separated; body more oblong-ovoidal and very smooth, the 

 prothorax relatively larger; scutellum flat, in closer, though not very close, 

 contact with the elytra. [Type M. basalts nov.] Microzalestes 



56 — Anterior coxae very widely separated; prosternum flat, not spinose in the 

 male. Beak not separated from the head by an impression, straight ( 9), 

 feebly arcuate and less slender (cf); antennae just behind the middle in 

 both sexes, the club very short, almost globular; body oval, with large and 

 smooth, laterally squamose prothorax, the elytra closely sculptured and with 

 partially lineate, dense vestiture. [Type R. marginatus nov.]. . . .Remertus 



Anterior coxae moderately to rather narrowly separated; prothorax relatively not 

 so large 57
