CARDIASTETHUS. 331 
1. Cardiastethus tropicalis, n. sp. (Tab. XIX. fig. 28.) 
Oblong ovate, shining, the elytra dull, finely pubescent and also with a few long scattered erect hairs ; piceous 
or piceo-ferruginous, the elytra testaceous, with the inner portion of the cuneus blackish, the dark 
coloration sometimes occupying the whole of the cuneus and extending to the apex of the embolium, the 
membrane smoky ; rostrum and legs testaceous ; antenne varying in colour from piceous to almost entirely 
testaceous. Head smooth, bifoveate between the ocelli; the eyes large and coarsely faceted in the male, 
smaller in the female; antenne with joints 1 and 2 moderately stout, 3 and 4 slender, 2 about three 
times as long as 1 and thickened towards the tip; rostrum not reaching beyond the anterior coxe. 
Pronotum rounded at the sides in front, the sides distinctly margined anteriorly, the anterior lobe almost 
smooth, the posterior lobe transversely rugose, strongly depressed on the disc in front, the base very deeply 
emarginate. Scutellum with a broad transverse rugulose depression before the apex. Elytra subparallel 
to the apex of the embolium, distinctly, not very closely punctate; the embolium narrow, at the apex 
about half the width of the corium; the membrane with an inner and an outer nervure distinct. Orifice 
of the metastethium long and curved. 
Length 24-3 millim. (¢ 2.) 
Hab. GuatemaLa, El Tumbador, Cerro Zunil, Las Mercedes (Champion); Panama, 
David (Champion).— ANTILLES, Grenada. 
Var. Above and beneath testaceous, the elytra more sparsely punctured. 
Hab. GvateMata, San Geronimo (Champion). 
Ten specimens. Not unlike the Palearctic C. fasctiventris (Garb.), but more shining, 
the elytra more sparsely and not so finely punctate. From Asthenidea pallescens, which 
is equally variable in colour, it may be separated by the deeply emarginate base of the 
pronotum, &c. | 
There are several examples of C. tropicalis from Grenada in the British Museum, 
mixed with the series of Lastochilus fraternus, Uhler, collected by Mr. H. H. Smith. 
2. Cardiastethus rugicollis, n. sp. 
Oblong ovate, shining, the elytra dull; pilose and with a few long erect hairs, the margins of the pronotum 
and embolium ciliate ; piceous, the elytra and antenne obscure testaceous, the legs testaceous. Head 
almost smooth, a little broader than long, the eyes rather large; antenne with joints 1 and 2 moderately 
stout, 3 and 4 slender and somewhat fusiform, 2 three times as long as 1; rostrum reaching as far as the 
posterior portion of the anterior coxe. Pronotum very short, rugose, with the callose portion of the 
anterior lobe smooth, deeply emarginate at the base and much narrowed in front, the anterior angles 
_ declivous, the sides obsoletely margined anteriorly. Scutellum with a deep, transverse, rugulose depression 
before the apex. Elytra somewhat closely punctate; the embolium narrow, at the apex about half the 
width of the corium; the membrane with an inner and an outer nervure distinct. Orifice of the meta- 
stethium long and curved. 
Length 2 millim. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith).—Antiutes, St. Vincent, Grenada. 
One specimen. Smaller than C. tropicalis, the pronotum shorter, more rugose, and 
more narrowed in front, the upper surface clothed with longer hairs, these projecting 
laterally, so that the pronotum and embolium appear to be ciliate at the sides. The 
present species is also extremely like various Lasiochili; but it may be separated from
