GONICCELUS.—DIPLOCGLUS., 621 
Elytra with regular and distinct series of punctures, which are a good deal masked by 
the short abundant pubescence, and are very indistinct behind. 
38. Gonicelus mollis, sp. n. 
Ovalis, convexus, piceus ; antennis pedibusque rufis, thorace sepe nigricante ; pube erecta vestitus, nitidus; 
elytris seriatim punctatis. 
Long. 24 millim. 
Hab. Guatemata, Capetillo, Cerro Zunil (Champion). 
This is a very aberrant species, with more slender antenne than usual, finely facetted 
eyes, and small prosternal process; on the upperside it is readily distinguishable by 
the soft erect pubescence. The thorax is greatly narrowed in front, and bears two 
raised lines on each side parallel with the lateral margin, the hind angles acute; disc 
convex, in front of the scutellum rather deeply impressed, so that the hind margin 
forms a sort of lobe in front of the scutellum. The elytra bear regular series of 
punctures, those near the suture being very obscure indeed, the others are made some- 
what indistinct by the abundant pubescence ; there is usually a more or less distinct 
band of white colour across the middle, due to the hair being more pallid there. 
Seven specimens. 
DIPLOCCELUS. 
Diplecelus, Guérin, Icon. Régne Anim., Ins. p. 196 (1888). 
This genus occurs in both Europe and North America, being represented by two 
or three species in each case. Of the two species here added, D. bicolor seems to be 
nearly allied to those already described; D. parvus is aberrant. 
1. Diplocelus bicolor, sp. n. 
Convexus, dense subtilissime pubescens, opacus, rufo-obscurus ; elytris pectoreque nigricantibus, elytris minus 
discrete seriatim punctatis. 
Long. 3 millim. 
Hab, GuaTeMa.a, Capetillo (Champion). 
Rather shorter in form and more convex and compact than the European D. fagi, 
Chevr., and with thinner antenne. Head moderately broad, without elevations, finely 
punctured. ‘Thorax very strongly transverse, transversely convex, the lateral margin 
fine and very densely set with quite short sete; the sculpture much obscured by the 
minute pubescence ; near the side with a fine raised line, which is a little curved 
inwards in front, without being continued along the front margin; a second much 
more obscure line nearly parallel with this exists; the disc is convex, very obscurely 
punctured, the hind margin thickened in front of the scutellum. Scutellum clothed 
with grey hair. Elytra with the sutural series of punctures almost obliterated, the
