CARPOPHILUS. 301 
longed and thickened at the extremity or just above it. The male of the small form 
found in California has a minute vague depression close to the hind margin of the last 
ventral plate: in the var. pollens this depression is large and preceded by a bare space, 
which is conspicuous amidst the granular sculpture of the segment. The male of the 
latter also has the hind legs larger than the female, and is usually much larger in size 
and of darker colours. Iam not sure there may not be two species, but the sexual 
differences of the two appear to be only degrees of development ; and the size and colour 
are so very variable that it is probable we have to do with only a single excessively variable 
species, exhibiting some local distinctions. 
This species and the following two would be sharply distinguished from the other 
Carpophili by the fimbriation of the lateral margins of the elytra, were it not that 
C. floralis forms in this respect a transition from the rest of the genus. 
According to Dr. Horn 3, C. pallipennis is sometimes abundant in the flowers of 
Cactus. 
34. Carpophilus canescens, sp. n. 
Fuscus, abdomine rufo, opacus, subtilius punctatus, pube longiore pallida conspicue vestitus, antennis pedibusque 
testaceis ; prothorace valde transverso, lateribus fortiter rotundatis, elytris prothorace multo longioribus. 
Long. 33 millim. 
Hab. Mexico, Etla (Sal/é). 
We have received only two female examples of this insect, and though they are in 
bad condition I describe the species, as it will be recognized with ease. It is allied to 
C. mexicanus, but is at once to be distinguished by the fine almost obsolete punctua- 
tion and by the fimbrie of the elytra; while from C. floralis and the allies of that species 
it is distinguished with certainty by the longer elytra. ‘The thorax is much narrowed 
in front, the base and hind angles completely rounded, so that the position of the latter 
cannot be detected; the punctuation is quite fine, moderately close, and much con- 
cealed by the long pubescence. The punctuation of the elytra is fine and obsolete. 
In the female the pygidium is broad and simple at the extremity, with an extremely 
fine margin. 
The colour will probably prove to be variable as in the allied species; the elytra are 
fuscous in one specimen, fuscous-yellow in the other. The fimbriation of the edges of 
the elytra is very conspicuous. 
85. Carpophilus longiventris, sp.n. (Tab. IX. fig. 19.) 
Convexus, opacus, minus dense pubescens et punctatus, rufus, pectore prosternoque in medio nigris, supra late 
sed vage fusco-tinctus ; prothoracis lateribus et angulis posterioribus rotundatis. 
Long. 4 millim. 
Hab. Mexico, Ventanas in Durango (Hége). 
Though we have received only one example of this species, it is clearly distinct from
