angulata, subconstricta, ab angulo ad medium sensim rotundato- 

 ampliata, lateribus ad marginem inferam latam compressiuscula, 

 prsesertim postice ; subperpendiculariter declivia. 



Pedes mediocres ; coxis sat magnis, subglobosis ; femoribus modice 

 clavatis, inermibus ; tibiis apice ampliatis, intus unco mediocri 

 armatis, anticis paulo incurvis, reliquis rectis ; articulo tarsorum 

 penultimo lato, profunde bilobo, ultimo biunguiculato, ungui- 

 culis basi liberis, divergentibus, simplicibus. 



Corpus suboblongum, exscutellatum, exhumeratum, squamosum, 

 mediae magnitudinis. 



This genus bears a striking resemblance to the Mediterranean 

 species of Geonemus (G. murinus, Sch., from Algiers) ; the forma- 

 tion of its rostrum and scrobs, of its exhumerate elytra, and the 

 absence of scutellum, place it in the second subdivision of the 

 Cleonidse of Schonherr, near Megalometis, &c. — H. Jekel. 



Synosomus geonemoides, Jekel. 



S, oblongo-ovatus, niger, squamulis laete virescentibus submetallicis 

 tectus ; rostro leviter tricarinato, basi subimpresso compressoque ; 

 thorace amplo, latitudine breviore, prope apicem transversim, me- 

 dio et basi utrinque, obsolete impresso ; elytris punctato-striatis, 

 interstitiis alternis postice convexis, mox pone medium ad suturam 

 elevato-carinatis, dein perpendiculariter declivibus.

General appearance of Geonemus murinus, but larger, thorax 

 more ample, &c. — (H. Jekel.) 



If this comes, as I believe it does, from the Pacific shore of 

 Central America, its alliance to a group from the other side of 

 the Pacific is particularly interesting in a geographical point of 

 view. Most of the species of Geonemus are from Australia or 

 New Guinea. — A. W. 



Sphenophorus dimidiatipennis, Jekel. 



£. ellipticus, niger, nitidus ; thorace supra elytrisque antice rufis, 



opacis, subholosericeis, subdeplanatis, illo maculis tribus, his sig- 



natura infra-humerali nigro-holosericeis ornatis.

Size, general outline, and deplanation that of Sphen. dispar, 

 Sch., but bearing a striking resemblance to Sphen. sericeus in the 

 coloration of the upper side ; the latter is nevertheless smaller, 

 narrower in proportion, and more convex, &c.
