CARPOPHILUS. 295 
quite dull, but only distantly and quite obsoletely punctate. Pygidium of the female 
simple. Two examples. 
Allied to C. ligneus by the form of the thorax, which, however, is not so strongly 
transverse, but differing in the ferruginous colour, the dull surface, and the obsoletely 
punctured elytra. 
§6. Mesosternum and metasternum simple; male with the supplementary segment 
covered by the pygidium ; form depressed ; pubescence not variegate. (Subgen. 
Microxanthus, Murray.) (Species 20-22.) 
20. Carpophilus confertus, sp. n. 
Depressus, dense punctatus, opacus, ferrugineus, capite elytrorumque marginibus infuscatis, antennis nigri- 
cantibus basi rufa; prothoracis angulis posterioribus subobtusis, fere rectis. 
Long. 3 millim. 
Hab. Mexico, Jalapa (Hége); Guaremata, Cerro Zunil, Zapote, Purula (Champion) ; 
Panama, Volcan de Chiriqui (Champion). 
Thorax very densely punctured, a little rounded at the sides, the base at the hind 
angles directed outwards without obliquity either forwards or backwards. Llytra 
densely and distinctly punctured, the suture and the outer and hinder margins blackish. 
Female with the pygidium simple, but rather more narrowed than usual at the 
extremity. 
By means of this species and C. dulcis there seems to be a complete transition froin 
the form of the thorax of C. senilis to that of C. ligneus. C. confertus may be distin- 
guished from C. dulcis by the more dense punctuation, and a slight difference in the 
form of the base of the thorax. The last ventral plate has in C. confertus similar 
punctuation to that preceding it, but in C. ducts the surface of the last ventral plate 
is dull and almost without sculpture. 
21. Carpophilus erichsoni, sp. n. (Tab. IX. fig. 18.) 
Parvus, latus, niger, pedibus sordide rufis, antennarum basi picea ; prothorace posterius latiore, lateribus haud 
curyatis, angulis posterioribus subacutis. 
Long. 24 millim. 
Hab. Guatemata, San Gerénimo, Balheu (Champion). 
Thorax with the front angles rather prominent, the sides not at all rounded, the basal 
and lateral margins very distinct, the hind angles projecting very slightly backwards, the 
surface rather closely and finely punctate, dull, not rugose. Punctuation of the elytra 
almost like that of the thorax. Seven specimens, all of the male sex. 
This little insect in form much resembles C. marginatus, Er., but has no ‘coxal line 
on the metasternum.
