180 HETEROMERA. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith); Guatemaua, San Joaquin and San 
Gerénimo in Vera Paz, Volcan de Atitlan (Champion); Nicaracua, Chontales (Janson). 
Two male and four female examples. A small shining species, with black head and 
thorax and testaceous elytra, the latter with a transverse curved black median fascia on 
either side; the pubescence is long, semierect, and rather coarse, and does not hide the 
punctuation ; the eyes are very coarsely granulated, large, and hairy; the hind femora 
are clavate in both sexes ; the anterior tibie in the male are slightly sinuate within and 
somewhat hooked at the tip. 
20. Xylophilus chiriquensis. (Tab. VIII. fig. 14, 3.) 
Closely allied to X. cinctipennis and differing as follows :—The antenne rather more elongate, black, the apical 
joint fusco-ferruginous; the median fascia of the elytra larger and broader, nearly reaching the suture 
but not continued upwards along the lateral margin; the anterior tibie ( ¢ ) curved to beyond the middle 
and then abruptly bent inwards, the inner edge sinuate, at the middle almost angulate, and furnished 
with a long sharp tooth at the apex. 
Length 23 millim. (¢.) 
Hab. Panama, Volcan de Chiriqui 3000 feet (Champion). 
One male example. This insect is extremely closely allied to X. cinctipennis, but 
the form of the male anterior tibie is very different. In our two males of X. cincti- 
pennis the anterior tibie are feebly curved without, sinuous within, and the tooth on 
the inner side at the apex is fine and short; in the male of X. chiriquensis the anterior 
tibie are very abruptly bent inwards a little beyond the middle, and the tooth at the 
apex is longer and stouter. 
21. Xylophilus xquinoctialis. (Tab. VIII. fig. 15, ¢.) 
Short and rather broad, subovate, shining, thickly clothed with long, semierect, ashy pubescence ; the head 
black ; the :prothorax reddish- or piceo-testaceous; the elytra testaceous or flavo-testaceous, with a 
black or piceous median fascia, the fascia nearly or quite reaching the suture, widened towards the lateral 
margin, and of variable width (in some specimens divided in the middle, in others narrow and sub- 
angulate), the scutellar region sometimes infuscate. Head large and broad, thickly and rather coarsely 
punctured ; eyes hairy, very large, very coarsely granulated, moderately emarginate, narrowly separated 
in the male, more distant in the female, occupying almost the whole of the side of the head (the head very 
narrowly extended on either side behind them); antenne entirely testaceous—( ¢) moderately long, 
rather stout, joint 2 rather more than half the length of 3, 3 longer than 4, 4-10 very slightly decreasing 
in length and increasing in width, 9 and 10 about as broad as long, 11 very much stouter than, and more 
than twice as long as, 10, ovate, acuminate—(? ) much shorter, joint 2 very little shorter than 3, 7-10 
strongly transverse, 11 about twice as long as 10; prothorax rather convex, a little narrower than the 
head, broader than long, the sides rounded and narrowing in front, straight behind, the surface thickly 
and somewhat coarsely punctured ; elytra short, rather convex, at the base about one half broader than 
the prothorax, a little rounded at the sides, widest at the middle, with a shallow oblique depression 
extending from the shoulders downwards towards the suture, closely and somewhat coarsely punctured ; 
legs rather stout, testaceous, the hind femora a little darker; the hind femora incrassate and the hind 
tibize a little thickened in both sexes; the anterior tibie slightly curved without and sinuous within, and 
with a short tooth on the inner side at the apex, in the male. 
Length 14-13 millim. (¢ 9.)
