XENETUS, gen. nov. 
Body elongate, pilose, somewhat shining. Head broad, deflected before the eyes, the central longitudinal 
sulcation not extending beyond the basal half; eyes large, prominent, slightly directed backwardly, and 
contiguous to the anterior margin of the pronotum ; antenne not quite so long as the body; basal joint 
about as long as the head or longer, second joint three times the length of the first, with its apical half 
more or less incrassated ; third and fourth joints slender, the third about half the length, or nearly as long 
as the second, and more than twice the length of the fourth. Pronotum elongate, subglobose, constricted 
about the centre; before this constriction the lateral margins are convex, and behind the same they 
obliquely widen to lateral angles which are non-prominent; posterior margin concavely sinuate at area of 
scutellum; anterior margin truncate. Scutellum with the basal third depressed, remainder somewhat 
tumid, the apex distinctly carinate. Corium with the margin concavely sinuate, widening towards cuneus, 
which is longer than broad. Legs finely, but longly setiform, the tibie prominently so. Rostrum just 
passing the intermediate, or reaching the posterior coxe. 
a. Basal joint of antenne about the length of the head ; third joint about half 
the length of the second. | 
1. Xenetus lanuginosus, n. sp. (Tab. XXIV. fig. 3.) 
Body above fuscous and finely pilose. Antenne with the first joint ochraceous, its base pale luteous and its 
apex slightly infuscated ; second joint ochraceous, its apical half fuscous; third joint very pale fuscous, 
with the apical half darker and its base very pale; fourth joint fuscous, with the base pale luteous. 
Pronotum very finely rugulose, the basal margin ochraceous. Scutellum with the apical half more or less 
obscurely castaneous. Corium with the claval area, a large central patch, and a large irregular apical 
spot very dark fuscous, the central patch containing a transverse subtriangular ochraceous spot. Cuneus 
ochraceous, inner base fuscous, inner apical area castaneous. Legs ochracéous, apices of the posterior 
femora dull castaneous. Body beneath fuscous, with the acetabula apparently ochraceous (carded 
specimen). Rostrum ochraceous, the apical portion pitchy. 
Variety (sexual or otherwise?). Pronotum with the disk longitudinally more or less ochraceous, scutellum 
sometimes wholly ochraceous, corium with the ground-colour either pale fuscous or brownish ochraceous ; 
legs variable in hue, sometimes altogether fuscous. 
Note. In this apparently variable species the size and the transverse subtriangular pale central spot to the 
corium seem to be indicative of its identity in all its protean forms. 
Long. 7-8 millim.
