PINOPHILUS. 621 
portance, and will also, no doubt, require separation from the Old World forms. 
Fauvel, indeed, intends separating an Asiatic form allied to my second group, under 
the name Leucotrichus. 
The different species are found on the sandy banks of streams (Champion). 
§ 1. Thorax oblong (Pinophilus verus). 
1. Pinophilus parcus. 
Pinophilus parcus, Lec. New Species N. Am. Col. p. 487. 
Hab. Norta America, Southern States !, New Orleans (coll. Sharp).—Mexico (coll. 
Sharp). 
The species of this group of Pinophilus are very difficult to separate, though the 
cedeagus indicates that they are valid. Hence I am not sure whether our insect be 
truly the species I have referred it to. In Chevrolat’s collection specimens were 
labelled P. flavipes, Er., and if this were correct I should have adopted the latter name ; 
P. flavipes is a Porto-Rican insect, and the description does not agree well with our 
species. I have only one Mexican exponent; but though I have retained no note as to 
the source whence I obtained it, I think the label probably correct. 
- In P. parcus the cedeagus is much broader than in any of the allied species of our 
region at present known to me, and the terminal ventral segment is much more 
prolonged. 
2. Pinophilus albipes. (Tab. XVI. fig. 13.) 
Pinophilus albipes, Er. Gen. et Spec. Staph. p. 675 ?. 
Hab. Mexico (Chevrolat 1, Flohr), Cordova (Sallé), Jalapa (Hoge). 
Very close to P. parcus, but with rather shorter and more coarsely punctate elytra, the 
segments of the hind body not margined with red, and with strongly marked differences 
in the cedeagus. Erichson’s type is now in my collection, and I am able to say that it 
was by some error that he described the sixth abdominal segment as being emarginate, 
as this is not the case. P. albipes is apparently not a common insect, and [I anticipate. 
from the short series before me that it will be found to vary a good deal in the sculp- 
ture of the anterior parts. 
8. Pinophilus erythropterus. 
Subopacus, niger; pedibus, palpis antennisque albido-flavis, his articulis extrorsum fuscescentibus ; elytris 
quam prothorax longioribus, rufis ; abdomine apice rufo, segmentis singulis rufo-marginatis, 
Long. 15 millim. 
Hab. Muxico (Flohr), Tuxtla (Sallé); Nicaragua, Chontales (Janson); Costa Rica, 
Cache (Rogers). | 
Head and thorax minutely punctulate, and with an additional coarse punctuation ;
