middle, and thence rounded in an elliptic curve to the apex of the suture; surface convex, obliquely 
declivous behind the middle, dull, and finely pubescent with dark hairs, fuscous-black, with an obscure 
brownish tinge towards the base, striate, the strize fine and obsoletely punctured ; interstices almost: flat, 
the first and succeeding alternate interstices with fine uniseriate sete, the second not impressed, and 
scarcely narrowed towards apex. Underside entirely fuscous-black, with short cinereous pubescence. 
Legs piceous. 
Hab. Guatemata, Cerro Zunil (Champion). 
One example. Extremely like the following species, with which, however, it is 
impossible to associate it even as a variety: it is rather larger, with the elytra 
distinctly more elongate and less obtuse behind; darker in colour, with the elytra 
not lighter towards the apex, the legs entirely piceous, and the abdomen fuscous- 
black. (In P. reitteri the elytra are usually, though not invariably, rufescent behind, 
the femora at least are testaceous, and the abdomen is testaceous-red.) The head is 
more distinctly rostrate in P. consocius, the elytral strie are much shallower towards 
the apex, the interstices are flatter, duller, and the second is not impressed behind ; 
the setee on them are more numerous, longer and finer, whereas in P. reitteri they are 
short, thickened, blunt, and conspicuously pale. The sculpture of the rostrum will 
probably be found to differ in the two sexes. 
2. Problechilus reitteri. (Tab. VI. figg. 21; 21 a, antenna.) 
Problechilus reitteri, Eichh. Rat. Tom. p. 169”. 
Hab. Muxico!, Jalapa (Hoge), Orizaba (Bélimek); GuaTEMALA, Zapote, Guatemala 
city (Champion); Panama, Bugaba (Champion). | 
The four specimens taken at Orizaba, now in the Vienna Museum, and the one from 
Jalapa, agree with the type which has been communicated by Herr Schaufuss, its 
present possessor. ‘Their length is about 2°3 millim. The fifteen examples of 
Mr. Champion’s collecting are all rather smaller (2 millim.), and slightly darker, the 
apex of the elytra, the knees, or tibie being sometimes infuscate. But the abdomen 
is always rufo-testaceous, and the femora pale, and it is sufficient to regard the more 
southern series as merely varietal. 
The basal testaceous patch on the prothorax is usually continuous from side to side, 
but is occasionally divided by a prolongation backwards of the dark area. The rostrum 
may be sculptured as in the preceding species, with a narrow side-margin, which does 
not extend to the upper angle of the eye, or it may be simply subconvex. ‘The difference 
is apparently sexual. 
3. Problechilus minor, sp. n. 
Ovalis, suboblongus, sat dense breviter pubescens ; fusco-niger, prothoracis apice et limbo basali testaceis, 
elytris testaceis, sutura et lateribus nigricantibus, vel omnino fusco-nigris, pedibus et abdomine testaceis ; 
prothorace granulis minus confertis asperato ; elytris minus opacis, tenuiter striatis, striis distincte punctatis, 
in declivitate profundioribus, interstitiis alternis uniseriatim setosis. 
Long. 1:6-1°8 millim.
