324 On new Scolytidae/rom Africa. 



face, the third near the tip, obliquely curved on both faces 

 and concentric with the apical margin. Prothorax trans- 

 verse, nearly semiglobose, with no side-margin. Elytra 

 raised and crenate at the base, overlapping the prothorax, 

 strongly spinous in the single species. Anterior coxae sub- 

 contiguous, separated by a narrow prosternal process ; middle 

 coxse widely separated ; abdomen short, the first four segments 

 successively decreasing in length. Anterior tibiae slender, 

 narrowed at the apex, feebly asperate above, and terminating 

 in a recurved uncus ; middle and posterior tibiae flattened, 

 not wide, the upper border rounded and finely dentate towards 

 the apex, of which the lower angle is spinous ; tarsi short, 

 the first two joints very small and difficult to observe, the 

 third longer, the apical joint as long as all the preceding. 



The genus appears to be related to Liparthrum and Hypo- 

 torus, differing in antennal structure. I have not been able 

 to dissect the mouth-parts, owing to the small number of 

 available specimens and their already mutilated condition. 



Styracopterus murex, sp. n. 



Breviter ovatus, opacus, squamis brevibus cinereis quasi crusta 

 opertus, obscure ferrugineus, capite, prothoracis apice, elytris 

 ad basin nigricantibus, antennis pedibusque testaceis ; pro- 

 thorace rugoso, medio rarius elevato-granulato ; elytris punctato- 

 striatis, ad basin interstitii 2 l cannula trispinata, cum crista 

 fortissime 4-spinata post medium interstitii 3 1 connexa, inter- 

 stitiis 5° a basin ad medium, 7° mox pone basin ad apicem spinis 

 erectis cristatis, margine apicali serrato. 

 Long. 1-4-2 mm. 



Short-oval, convex, dull, covered thinly with very small 

 cinereous scales, which give it a dirty appearance. Head 

 black, front with a transverse impression, crossed by a fine 

 elevated longitudinal line, pilose above ; mouth densely 

 fringed with fulvous hairs ; antennae yellow-testaceous, the 

 scape fringed with a pencil of very long hairs. Prothorax 

 much broader than long, narrowed in front, the sides rounded 

 throughout, the apex somewhat obtuse, the base bisinuate ; 

 strongly convex above, somewhat gibbous in the middle, and 

 declivous in front, obscure ferruginous, with the apex blackish, 

 rugosely punctured, the punctures containing appressed 

 scales, the sides with a few longer scales ; median portion of 

 disk with small scattered elevated granules. Scutellum 

 absent. Elytra about as wide as the thorax and more than a 

 half longer, their basal margins elevated and serrate, over- 

 lapping the prothorax, the sides straight to the middle, thence 

 broadly rounded to the apex ; surface obscure ferruginous,
