Species of the American Genus Astylus. 353 



than long, truncate at the tip. Tegmen with very long, 

 rather narrow, lateral lobes, which are slightly incurved and 

 rounded at the apex, their lower and apical margins flavo- 

 ciliatc. Penis-sheath drawn out into a rather long slender 

 point, which is thickened at the tip. 



Hal. Brazil 13 , Eio Janeiro 5 (oV Orbigny 4 , C. Darwin, 

 Fry, &c). 



A common insect in Brazil. The long series examined 

 shows scarcely any variation in the peculiar elytral markings. 

 The type in the Banksian collection is a male. 



21. Astylus vittatus. 



Astylus vittatus, Gorh. Biol. Centr.-Am., Coleopt. iii. 1, pp. 127, 330, 



t. 7. fig. 9 (excl. example from Venezuela). 

 Astylus vittatus, Gorh., var. cJiiriquensis, Pie, Melanges exot.-entom, 



xii. p. 7 (Jan. 1915). 



c? . Elytra rounded at the apex. Ventral segment 5 

 deeply arcuato-emarginate, 6 moderately long, subcorneal, 

 smooth, grooved down the middle posteriorly, and feebly 

 notched at the tip. Tegmen bifurcate at apex, excavate at 

 the tip above, the apical portion clothed with long, curled, 

 blackish hairs. Penis-sheath acuminate at tip. 



? . Elytra obliquely subtruncate at the apex. 



Hah. Panama, Chiriqui. 



Found in abundance in Chiriqui. The variety has the 

 flavous or reddish stripes (juxta-sutural and discal) on the 

 elytra coalescent anteriorly, and the inner costa well defined. 

 The metasternum is without tubercles in $. The sexes 

 were not identified by Gorham. The unarmed apices of 

 the elytra in $ separate A. vittatus from various similarly 

 coloured forms. 



22. Astylus pallipes. 



Astylus pallipes, Kirsch, Abhandl. Zool. Mus. Dresden, 1888-89, no. 4, 

 p. 11, t. 7. fig. 22. 



Hab. Ecuador, Quito (ex coll. Murray), Loma de Canam- 

 ballo [type]. 



A female example from Quito, in the Museum, from the 

 Fry collection, is evidently referable to this species. It is 

 black, with the antennae in great part, the tibise (except at 

 the base), and tarsi testaceous; the elytra flavescent, with 

 the suture, outer margin, two lines on the disc, and the tip 

 black, the surface very coarsely punctured.
