 posterioribus) subito ampliatis, parte ampliata dense spinulosa ; tarsis

(Genus inter Cossonidas valde anomalum, tibiarum structure, necnon 

 abdominis segm tis i mo et 2 do inter se profunde divisis cum Hylesinidis 

 melius congruens, tamen, nisi fallor, ad hanc familiam vere pertinens. 

 Prsecipue exstat unco tibiali obsolete, tamen tibiis versus apicem exter-

 crasso parallel latiusculo sub-depresso piceo-ferrugineo ac dense argu- 

 teque sculpturato, elytrorum interstitiis costiformibus, sed costis quasi 

 e duabus efformantibus, rostro breviusculo parallel necnon a fronte 

 conspicue diviso, prothorace magno sub-quadrangulari, abdominisque

FAMILY SCOLYTIDES. 



Head of variable form ; terminating in a short muzzle, often almost 

 obsolete. Mentum prominent, its base generally received into a hollow 

 of the under-chin ; the ligula placed behind it and projecting, or not, 

 beyond its front margin. The maxillce with one lobe. Palpi very 

 short ; the labial with one to three, the maxillary with three or four, 

 joints. Mandibles seldom projecting, arched at the extremity, often 

 wide, and more or less denticulated inwardly. Antenna, inserted on the 

 sides of the muzzle or between the eyes and mandibles ; short, genicu- 

 lated, with from three to twelve apparent joints, the last forming a club 

 of variable form, sometimes pectinate. Eyes variable, ordinarily large 

 and transversal. The pronotum frequently confounded with the flanks 

 of the prothorax. Anterior coxa contiguous or not, their cotyloid cavi-
