New or little-known Xylophilidae. 59 



subquadrate, abruptly narrowed in front, bifoveate at the base. 

 Elytra oblong, much wider than the head, feebly transversely de- 

 pressed below the base, the humeri rounded. Legs slender, rathei 

 short; posterior femora moderately thickened and furnished with 

 a very narrow projecting pad along their lower face. 

 Length 2, breadth 1 mm. 



Hub. Brazil, San Paulo (Fry). 



One male. An oblong nigro-piceous insect, with slender 

 testaceous limbs. The apical joint of the antennae abruptly 

 stouter, the posterior femora with a narrow projecting pad 

 along their lower face, much as in the same sex of X. 

 fragilis, bicolor (renamed championi by Pic), unifasciatus 

 and inflatus, Ch. X. jlavipes is so like X. dryophiloides, 

 from the same locality, that it was at first treated by me 

 as the § of the same species; the difference in the form of 

 the antennae, however, is too great to be simply sexual,* 

 and the structure of the posterior femora is certainly that 

 of a male. 



73. Xylophilus fuscofasciatus, n. sp. 



$. Short, broad, subopaque, thickly clothed with line silky 

 pubescence; obscure ferruginous, the elytra brown, with a common ; 

 narrow, transverse, fuscous fascia just behind the middle, the 

 antennae and legs testaceous; the entire upper surface densely, 

 finely punctate. Head short, very little wider than (he prothorax; 

 eyes moderately large, distant, feebly emarginale, occupying almost 

 the whole of the sides of the head; antennae short, joints 1 and 2 

 stout, 3-6 slender, subequal in length, .'} slightly longer than 2, 7-10 

 rapidly widening, 10 transverse, 11 stout, ovate, obliquely acuminate-. 

 Prothorax strongly transverse, the angles obtuse, the disc shal- 

 lowly bifoveate at the base. Elytra broad, much wider than the 

 head, somewhat rounded at the sides, shallow! v. transversely de- 

 pressed below the base. Legs short, slender, the posterior femora 

 a little stouter than the others. 



Length (with head retracted) li, breadth 1 mm. 



Hub. Brazil, Rio de Janeiro {Fry). 



One specimen. A short, broad, densely punctate, sericeo- 

 pubescent, reddish-brown insect, with broad, faintly uni- 

 fasciate elytra, short, slender limbs, and very feebly emar- 

 ginate eyes, which occupy almost the whole of the sides of 



* (ireater than between the sexes of the European X (Euglenes) 

 pygmaeus, de Geer.
