190 HETEROMERA.

One example, probably a female. This small species has the eyes quite unemarginate 
and distant from the base of the head, and in this respect it resembles an Anthicus (the 
eyes, however, are transverse, and not oval asin Anthicus); the thorax is broader than 
long and a little dilated at the sides in front; the antenne are long and slender, with 
the second joint very little shorter than the third and the apical three joints stouter 
than the preceding ones; the elytra are comparatively broad and short, widened from 
the base to beyond the middle, and have a spot on either side of the suture at the base 
and broad zigzag fascia just beyond the middle. 
36. Xylophilus tantillus. (Tab. VIII. fig. 28, ¢.) 
Short and rather broad, opaque, densely clothed with fine, silky, appressed, ashy pubescence ; the head black ; the 
prothorax and scutellum ferruginous; the elytra brownish-testaceous, with a rather broad angulated 
black fascia below the middle, the fascia not quite reaching the suture, and connected laterally with a 
marginal brownish stripe (not visible from above) which extends from the fascia upwards to the base. 
Head very large and broad, densely and finely punctured; eyes (¢) very finely pubescent, very large, 
occupying the whole of the side of the head (the head not at all extended behind them), rather narrowly 
separated, coarsely granulated, somewhat feebly emarginate; antenne (g) long and pubescent, piceous- 
brown, the two basal joints lighter, joints 1-3 slender and shining, 4—11 stout, equal in width, and opaque, 
2 and 3 very short and equal in length, 4 more than twice as long as, and very much stouter than, 3, 4-10 
subequal, 11 considerably longer than 10, ovate, acuminate; prothorax transverse, much narrower than 
the head, the sides rounded and converging in front, straight behind, the surface very densely and some- 
what roughly punctured ; elytra rather broad, much wider than the prothorax, widest at the middle, the 
sides straight in front, the surface very closely and finely punctured ; beneath, the prothorax excepted, 
piceous ; the legs (including the femora) very slender, rather short, testaceous, the apical half of the tibise 
infuscate. 
Length 14 millim. (¢.) 
Hab. Guatemata, San Gerdnimo (Champion). 
One male example. This minute species belongs to the section Aderus, Westw., it 
having the second and third joints of the antenne very short and equal in length. 
Aderus contains one European species, A. boleti (Marsh.)=populneus, Panz., this being 
a very much larger insect than X. tantillus; and the Japanese X. gibbulus, Mars., also 
belongs to it *. 
Fam. ANTHICIDA. 
Leconte and Horn [Class. Col. N. Am. p. 409 (1883)] include the “ Pédilides ” (less 
Scraptia and its allies) and the “ Anthicides” of Lacordaire in one family, Anthicide: 
this arrangement is here adopted, with the exception that their “ Xylophilini” are 
excluded. This is a family more numerously represented in temperate than in tropical 
regions; we have, however, to enumerate a large number of species from Central 
America, whence two only have hitherto been recorded. We have as yet received 
very little material from the sea-coast, or from the interior of Northern Mexico. 
* Since ay remarks on the genus were written (anted, p. 166), I have found a single specimen of a 
Xylophilus in Herr Hége’s Mexican collection ; it is a male of an undescribed species allied to X. bicolor.
