VALDASUS.—VANNIUS. : 245 
marginal spot to corium completely absent. Clavus with a short linear ochraceous spot on each side 
near apex; cuneus testaceous or castaneous, the base transversely luteous; membrane smoky hyaline or 
very pale fuscous; clavus with two oblong spots (one on each side of central suture), and corium with 
a large irregular apical spot dark velvety brown. Body beneath much as in preceding species, but paler. 
V. cerbereus also differs from V. erebeus in having the pronotal angles distinctly subnodulose, the corium and 
pronotum less coarsely punctate, the scutellum not globose, but with a distinct and broad central longi- 
tudinal carination, &c.

7. Valdasus stygius, n. sp. (Tab. XXIV. fig. 9.) 
Body above dark castaneous; head dull ochraceous with two small central fuscous spots; antenne with the 
first and second joints pale castaneous, the base of the first and the apex of the second pale luteous, third 
and fourth very pale fuscous; apex of scutellum, a very small spot at marginal base, and a large sub- 
quadrate spot about centre of lateral margin of corium, a smaJl spot on each side of apex of clavus, and 
apical margin of corium greyish white; cuneus greyish white with the apex fuscous; membrane pale 
fuscous with some obscure greyish markings ; femora luteous, irregularly annulated with castaneous ; tibie 
and tarsi castaneous. Body beneath (carded specimen) with the head, coxe, posterior margin of meta- 
sternum, and disk of abdomen (imperfectly seen) luteous or ochraceous. 
This species is more or less distinctly pilose; the pronotum is thickly and coarsely punctate, very broad 
posteriorly, the lateral angles obtusely rounded and subnodulose; the scutellum is transversely wrinkled 
and punctate, with its base depressed; the corium is sparingly and finely punctate. 
Long. 5 millim. 
Hab. Panama, Bugaba (Champion). 
The great width of the pronotum at base, irrespective of general colour and markings, 
at once separates this from the two preceding species. 
8. Valdasus rugosus, n. sp. (Tab. XXIV. fig. 10.) 
Above shining black and extremely rugose;.antenn# fuscous, the apex of the second joint luteous; a small 
spot at basal margin of corium, a linear spot on each side of clavus near apex, and basal margin of 
cuneus obsure greyish; membrane fuscous, basal cellular areas blackish; basal angles of scutellum and 
an elongated spot on each side of apical claval suture deep velvety black ; legs castaneous, femora with the 
base and a subapical annulation luteous, apices of tarsi luteous. Body beneath concolorous, posterior 
cox (anterior and intermediate coxee unexamined owing to specimen being carded) luteous. 
Pronotum with the anterior area globosely nodulate and profoundly sulcate, the base with two central contiguous 
smaller nodulations, the lateral angles obtusely rounded; scutellum with a central basal foveate impres- 
sion, the apical portion gibbous, posteriorly deflexed and centrally carinate, corium obliquely and 
irregularly rugosely striate. .

VANNIUS, gen. nov. 
Allied to Valdasus. Head slightly and conically produced in front of the eyes, and then vertically deflexed, and 
with a slender central longitudinal sulcation ; eyes contiguous to the anterior margin of the pronotum, 
but less prominent than in Valdasus. Antenne with the basal joint stout and incrassated, not quite the 
length of the head; second, third, and fourth joints slender; the second twice the length of the first, and 
subequal in length to the third. Pronotum subtriangular, with an anterior transverse constriction, the
