New or liMe-Tcnown Xylopkilidae. 57 



more coarsely, punctate. Head short, broad, narrowly subangu- 

 larly extended on each side behind the eyes, the latter large, emar- 

 ginate, and separated by about half their own width; antennae 

 rather stout, comparatively short, joint 3 slightly longer than 2, 

 3-10 gradually decreasing in length, 8-10 transverse, 11 stout, as 

 long as 9 and 10 united, obliquely acuminate. Prothorax strongly 

 transverse, nearly as wide as the head, parallel-sided, almost un- 

 impressed. Elytra short, broad, slightly rounded at the sides, 

 unimpressed. Legs moderately long, tho posterior pair stout, with 

 the femora strongly clavate and the basal joint of the tarsi curved. 

 Length I i, breadth 1 mm. 



Hab. Amazons, between Para and Santarem (//. //. 

 Smith). 



One specimen, assumed to be a female. A short, broad, 

 convex form, with broadly nigro-fasciate elytra, a dark- 

 head and prothorax, and the rest of the upper surface (a 

 faint scutellar patch excepted), the antennae, and legs (the 

 posterior femora excepted) testaceous. A fragmentary <£, 

 from Tole, Panama, provisionally placed by me under 

 X. aequinoctialis, Ch. (B. C.-Am., Coleopt. iv, 2, p. 181), 

 with the eyes much larger and subcontiguous, the tri- 

 angular scutellar patch darker and well denned, and the 

 anterior tibiae feebly curved and subsinuate within, seems 

 to belong to the same species. 



70. Xylophilus amazonicus, n. sp. 



<£. Oblong, somewhat depressed, subopaque, clothed with very 

 fine sericeous pubescence; nigro-piceous, with the anterior margin 

 of the prothorax and the under surface obscure ferruginous, the 

 mouth-parts, antennae, and legs, and the base of the elytra broadly, 

 testaceous; the entire upper surface densely, minutely punctate. 

 Head large, broad; eyes very large, occupying the whole of the 

 sides of the head, feebly emarginate, somewhat narrowly separated 

 above; antennae slender, moderately long, joint 3 much longer 

 than 2, 3-10 very gradually decreasing in length, longer than broad, 

 11 acuminate-ovate. Prothorax much narrower than the head, 

 broader than long, subquadrate, narrowed in front, with a broad 

 transverse depression before the base. Elytra oblong, much wider 

 than the head, gradually widened to the middle, transversely de- 

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

 moderately incrassate and with a narrow pallid pad along their 

 lower face.
