1. Triclis argentifacies, sp. n. (Tab. V. fig. 22, s .) 



c? . Black. Antennae black, the third joint dark red ; first joint with black bristles below, abont twice the 

 length of the second ; the third rather longer than the first two together, the style minute. Front 

 yellowish-grey-pollinose, with black hair on the sides. Pace most prominent at the oral margin, covered 

 with close-lying silvery-white hair, which is long and thatch-like on the lower portion, concealing in 

 part the black bristles of the oral margin. Occiput grey, with white hair below. Mesonotum opaque 

 brown, with close-lying short hair, which is brown in the middle and whitish on the sides ; a broad 

 median stripe and two large spots on each side, not distinctly differentiated, darker brown. Pleurae 

 thickly white-pollinose ; in the middle with a shining, vertical black spot. Scutellum with short 

 yellowish-white hair above; no bristles on the margin. Abdomen brownish-black, very finely roughened, 

 due to abundant microscopic hairs ; hair on the sides longer, white ; all the segments with a narrow 

 white hind margin, which becomes broader towards the sides. Legs black ; underside of all the femora 

 and the base of the tibiae red, clothed with close-lying, short, white hair ; on the inner side of the front 

 and hind tibiae and tarsi velvety-yellow. Wings nearly hyaline ; first and fourth posterior cells closed at 

 some distance from the margin of the wing. Length 8-9 millitn.

BLEPHAREPIUM. 



Blepharepium, Rondani, Studi Ent. i. p. 89 (1848). 

 Planetolestes, Lynch, antea, p. 171. 



l. Blepharepium coarctation. 



Laphria coarctata, Perty, Del. Anim. art. Brasil, p. 181, t. 36. fig. 4 1 . 



Blepharepium coarctatum, Lynch, An. Soc. Cient. Arg. viii. p. 145 2 ; v. d. Wulp, Tijdschr. voor 



Ent. xxv. p. 88 3 . 

 Planetolestes secabilis (Walk.), O. Sack, antea, p. 171 *. 



To the localities given, add : — Mexico, Tepetlapa in Guerrero, Medellin in Vera 

 Cruz, Teapa in Tabasco (H. H. Smith), Atoyac in Vera Cruz (H. H. Smith, Schumann), 

 Santiago Iscuintla in Jalisco {Schumann). — Beazil 1 ; Aegentina 2 3 . 



Osten Sacken adopts the generic name Planetolestes, instead of Blepharepium, for 

 this species ; but there can be no reasonable doubt that it is the one to which Rondani 

 gave the name Blepharepium. If every genus has to be correctly and fully diagnosed 

 before it can be accepted, I am afraid there would be no end of confusion.
