Species of the American Genus Astylus. 361 



32. Astylus antillarum. 



Astylus antillarum, Gorli. P. Z. S. 1898, p. 328, t. 27. fig. ~ (d 1 ). 



cJ . Metasterimm with two, curved, outwardly-directed, 

 dentiform processes arising from a tumid space in the middle 

 behind. Ventral segment 5 deeply areualo-emarginate, 

 6 long, compressed (subcylindrical as seen in profile with 

 the terminal dorsal segment). 



/lab. Antilles, St. Vincent. 



Described from a single pair — the <$ now in the British 

 Museum, the $ having passed into Pic's collection, from that 

 of Gorham. The ? has the apices of the elytra deeply 

 excised, as in the same sex of the allied forms. The spots 

 are too red in the published figure. 



33. Astylus gorhami. 

 d . Astytus gorhami, Pic, Melanges exot.-eutom. xii. p. 8 (Jan. 1915). 



Elongate, moderately shining, clothed with long, erect, 

 black bristly hairs intermixed with scattered fine, ad- 

 pressed, cinereous pubescence, the latter somewhat con- 

 spicuous along the elytral suture in ? , the vestiture of the 

 legs and under surface long, cinereous ; black, the' antennal 

 joints more or less rufescent externally or at their base, the 

 elytra each with a pyriform patch on the disc at the base, a 

 mesially-constricted, apically widened, elongate streak on 

 the disc below this, a subquadrate patch near the tip, and 

 the outer margin in great part, orange-yellow ; the head and 

 prothorax densely, finely punctate, the latter with coarser, 

 punctures intermixed, the elytra roughly punctured, smoother 

 in the depressed juxta-sutural area in $ . Head long, narrow, 

 subrosirate ; antennae short, joints 7-10 transverse in $ . 

 Prothorax about as long as broad, narrowed anteriorly. 

 Elytra long, sharply margined, costate laterally from the 

 humeral callus to the common transverse apical depression, 

 and with a faint costa on the disc also, the space between 

 this and the suture and another within the outer ridge longi- 

 tudinally depressed, conspicuously so in ? ; the apices blunt 

 or subtruncate in <$ , and deeply semicirculaily excavate (the 

 sutural and outer angles thus appearing sharply dentate) 

 in ? . 



£. Metasternum with two compressed, curved, outwardly 

 directed dentiform processes arising from a tumid space in 

 the middle behind. Ventral segment 5 as long as 3 and 4
