New or Wile-known Xylophilidae. 51 



a peculiar character, the slender spine in the $ correspond- 

 ing to the tuft of hairs present in the same sex of X. 

 lacertosus, forlicomis, humeralis, and v-notatus. The male 

 probably has a long apical joint to the antennae. 



61. Xylophilus forticornis, Champ. 



The types of this species were from Chiriqui, Panama, 

 and Pic (Ann. Soc. Ent. Fr. 1912, p. 281) has since recorded 

 it from Trinidad, from a $ found by Mr. Bryant. In the 

 Fry collection there is a $ from Rio de Janeiro with the elytra 

 uniformly fuscous, and the pubescence not condensed into 

 definite markings or fasciae, which must, for the present, 

 be referred to the same species. X. (Elonus) crassicornis, 

 Pic, from Santa Pita, Boa Sorta, and Petropolis, seems to be 

 an allied form with enormously developed posterior femora 

 in $; X. (Elonus) distincticornis, Pic, from Pernambuco, 

 has the head and prothorax partly reddish. 



62. Xylophilus triguttatus, n. sp. (Plate II, fig. 28, $.) 



<J. Oblong, rather convex, shining, sparsely, finely pubescent; 

 head, basal joint of antennae, prothorax, posterior femora, and the 

 intermediate femora at the middle, nigro-piceous or black, the rest 

 of the legs and antennae, and the palpi, testaceous; the elytra 

 testaceous, with a common, transverse, triangular acutellai patch, 

 and a broad space at the middle of the disc (extending from near the 

 suture to the outer margin and there continued forwards to near 

 the humeri), nigro-piceous ; closely, finely, the elytra more coarsely, 

 punctate. Head short, broad, extended on each side behind the 

 eyes, the latter large, deeply emarginate, and separated by about 

 half their own width; antennae rather stout, moderately long, 

 joint 3 slightly longer than 2, 4-10 subequal, as long as broad, 4 a 

 little stouter than 3, 11 nearly as long as 9 and 10 united, ovate. 

 obliquely acuminate. Prothorax subquadrate, convex, much nar- 

 rower than the head, nearly as long as broad, narrowed in front, the 

 disc shallow] y transversely grooved on each side at about the middle. 

 Elytra wider than the head, somewhat rounded at the sides, gradually 



narrowed from a little below the base, with a deep, oblique, intra- 



humeral depression. Legs rather stout, moderately long; anterior 

 tibiae slightly curved, subangularly dilated on the inner side beyond 



the middle, and armed with a long, Bharp mucro at the inner apical 



angle; posterior femora stout, strongly clavate, abruptly excavate
