JORDAN—COLEOPTERA: ANTHRIBIDA 259 
12. Cleranthribus anthicopsis, spec. nov. (Plate 15, figs. 7, 7 a, 7 b). 
g. Rufus, prothoracis medio elytrorumque macula transversa antemediana suturam 
non attingente et plaga apicali nigro-brunneis, rostro carina mediana instructo, prothorace 
magis convexo quam in C. colydiopsi, omnino sparsis pilis vestitus, absque fasciis et maculis 
albis, lateribus meso- et metasterni exceptis. 
Long. (cap. excl.) 2°6 mm. 
Only 1 ¢, which has the facies of an Anthicus on account of the prothorax being more 
swollen than in C. colydiopsis. 
The antenna, which is entirely pale rufous, is rather longer than in the f¢ of the 
previous species, particularly segments 9 and 10, 9 being about one-third longer than it is 
broad. The pronotum is strongly convex about the centre, rounded at the sides, gradually 
narrowing from the middle to the apex. The lateral carima is somewhat longer than in 
colydiopsis. The elytra also are rather more rounded and somewhat broader than in the 
other species. There are no white markings on the upper side, and the dispersed hairs are 
rather longer than in colydiopsis, particularly in the neighbourhood of the scutellum. The 
postbasal depression, which in colydiopsis is rufous and bears a white band, is partly 
occupied in anthicopsis by a large brown spot, which is widest laterally, but reaches neither 
the suture nor the lateral margin; the brown apical area occupies about two-fifths of the 
elytra, but is not sharply defined and presumably varies individually. The legs are longer 
than in colydiopsis, the first tarsal segment being longer than the claw-segment.

ScIRTETINUS, gen. nov. 
a2. Generibus Choragus Kirby (1818), Acarodes Woll. (1879) atque Holostilpna 
Jord. (1907) dictis affinis. Nitens, absque pubescentia. Antennze setis longis vestite, 
clavee articulis valde remotis. Pronoti carina antebasalis basi parallela, lateribus ad 
medium usque continuata. Tibiz quatuor posticze supra ad apicem excise vel oblique 
truncate ac ibi setis brevibus vestitee.—Genotypus: S. ewmelas, spec. nov. 
The body is as strongly convex as in the allied genera, particularly Acarodes and 
Holostilpna, the dorsal outline from the apex of the pronotum to the tip of the pygidium 
being almost evenly curved except for a small interval between the antebasal carina of the 
pronotum and the basal edge of the elytra. The species are glossy black or brown without 
any pubescence. The head can be retracted into the prothorax, in fact, it is only exserted 
in a few specimens of the collection, as a rule only the antennze and the tip of the 
mandibles projecting from the cavity of the thorax. The skeleton is very firm, especially 
the under surface. 
The mandible bears a tooth near the apex. The fourth segment of the maxillary 
palpus is as long as the preceding segments taken together, but much slenderer, being 
elongate-conical with the tip truncate. The labial palpi have a very slender end-segment, 
while the other two segments are rather stout. The labium is entire, its apex only being 
feebly sinuate.
