SCAPHENGIS.— COCCIMOBPHUS. 83 



Elytra gibbosa, epipleuris latis, ad apicem attenuatis, leviter plicatis. Presternum obsolete rugoso- 

 punctatum ; processu longo, subparallelo, apice rotundato. Linese metasternales et abdominales obsoletae. 

 Pedes modiee longi, tarsis haud multo elongatis. 



This new genus is necessary for a small but very interesting Mexican insect. It is 

 allied to the Colombian Euphanistes, one of the most anomalous genera of the Erotylidse ; 

 Scaphengis differs from it, however, in form, being broader in front. The antennae are 

 differently constructed — in Euphanistes the joints succeeding the third are long, and the 

 third itself is particularly long ; in Scaphengis the corresponding joints are subequal 

 and fusiform. Other differences of hardly less importance are noticed in the diagnosis. 

 This singular genus is one of M. Salle's discoveries, I have not seen anything else like 

 it in any collection. 



l. Scaphengis picipes. (Tab V. fig. 6.) 



Oblongus, convexus, gibbosus, postice ovato-attenuatus, niger, nitidus, fere glaber ; antennis, palpis pedibusque 

 rufo-piceis ; protboracis lateribus anguste marginatis, basi punctato-plicata ; elytris sutura ad basin 

 depressa. Long. 5-6 millim. 



Hal. Mexico, Toxpam (Salle). 



Eyes small, but very coarsely granulate ; epistome thickly punctured ; antennae long, 

 but not much longer than the head and thorax ; the latter is subquadrate, the breadth 

 being rather greater than the length, the sides are parallel for about the basal half, and 

 the hind angles are nearly rectangular ; the base of the elytra is a little excised on each 

 side near the humeri to receive the thorax, which is closely applied to them, but the 

 humeri themselves are acute. The thorax and the elytra are quite smooth and glabrous, 

 with the exception of the few punctures or plicae on the extreme basal edge on each 

 side of the middle. The underside is rather strongly scaphiform ; on the prosternum 

 and in some other parts there are a few obsolete but largish punctures ; and bordering 

 the hind coxae a row of punctures are to be seen which probably represents the edge of 

 the coxal " plaque abdominal " and abdominal lines, which are otherwise quite absent. 

 The whole of the hind-body is rather uneven, from a very obsolete coarse punctuation, 

 and is very faintly pubescent. 



This insect has very much the appearance of some small forms of Tenebrionidae. 



Three specimens.

Coccimorphus is a genus of about fourteen species which are almost confined to 

 Tropical South America, but with a few representatives in Central America. It is only
