SOSYLUS. 481 
appears to me, however, impossible to reconcile Fabricius’s brief description with our 
insect, the most salient point he alludes to being the “ thorax levis,” a term totally 
inapplicable to S. terminalis. 
2. Sosylus strigicollis, sp. n. 
Parum elongatus, niger, opacus, capite, antennis pedibusque rufis; prothorace parum elongato, densissime 
striguloso ; elytris costatis, costa prima apice libero, intervallis subtiliter striguloso-sculpturatis. 
Long. vix 4 millim. 
Hab. Panama, Bugaba (Champion). 
Kpistome narrow in front, the margin in the male slightly retuse, so as to appear 
bituberculate ; surface finely punctate. Thorax narrow, moderately elongate, a little 
narrowed behind, the whole of its upper surface evenly covered with a dense strigose 
sculpture. LElytra costate, the first costa strongly elevated and quite free at its ex- 
tremity, the intervals bearing a dense fine sculpture consisting of many minute lines. 
This species resembles a small S. terminalis, but is very different in the thoracic 
sculpture and the sexual distinctions. We have received only three examples, two of 
which have been injured, in all probability by the process of extracting them from 
their burrows in the wood. 
8. Sosylus simplex, sp.n. (Tab. XV. figg. 13; 13.4, front of the head; 13 8, 
base of the antenna.) 
Sat angustus, niger, pedibus piceis, antennis rufis ; capite prothoraceque fortiter punctatis; elytris costatie, 
costis prima et tertia mox ante apicem conjunctis, intervallis punctatis. 
Long. 43 millim. 
Hab. Mexico, Las Vigas (Hoge); Brittso Honpuras (Blancaneaur); GuatEMALa, 
Panzos, Chacoj, and San Juan in Vera Paz, El Reposo, Zapote (Champion). 
Epistome simple. Head and thorax coarsely and closely punctate, the latter only 
moderately long, a good deal narrowed behind, the punctuation in front very dense. 
Elytra distinctly costate, the second and third coste uniting a little before the tip, and 
the first and third almost at the tip; the broad intervals bear a distinct, though 
shallow punctuation. 
This seems to be the least rare of our ‘species, and I am not able to distinguish the 
sexes; the gene are simple. 
4. Sosylus affinis, sp. n. 
Angustus, niger, subnitidus, pedibus piceis, antennis rufis; capite prothoraceque fortiter punctatis; elytris 
~ costatis, costis prima et tertia ad apicem vix conjunctis, ‘intervallis tristriatis, striis integris. 
‘Long. 44 millim. 
Hab. British. Honpvuras, Belize (Blancaneaux); GUATEMALA, Chacoj in Vera: Paz
