Coleopterous Suh-Family Byrsopince {CitrculionidcB). 59 



Type in the Berlin Museum. 



This description is made from specimens from German E. Africa, 

 which agree entirely with Kolbe's description. The Ehodesian 

 specimens differ in having the rostral fovese much less evident, the 

 basal one usually containing a small central tubercle or carina ; the 

 elytra, too, are generally much less rugosely foveate, the foveas 

 being smaller and more distinctly reticulate, and the alternate rows 

 of smaller tubercles are usually more or less obsolete. In all 

 the specimens which I have seen the mesosternal tubercle is 

 entirely wanting. 



5. HOPLITOTRACHELUS OMISSUS, PaSC. 



Brachycerus omissus, Pasc, Trans. Ent. Soc. L. 1887, p. 11 

 pi. i., fig. 6. 



H. foveiceps, Quedf., Berl. Ent. Zeit., 1888, p. 288. 



Long. 101-111; lat. 6I-61 mm. 



Head convex on the vertex, and with scattered shallow punc- 

 tures, the superciliary ridges moderately elevated, the forehead 

 with two shallow depressions separated by a faint carina. 

 Bostrum acuminate, but not elevated, at the base, the dorsal 

 margins obtusely angulated about middle, and the disk with four 

 large shallow foveas. Prothorax convex, rugosely foveolate, with a 

 broad transverse impression near apex, divided by a central carina ; 

 the apical callus comparatively narrow, not lobate posteriorly, and 

 with its anterior edge only shallowly emarginate and scarcely 

 produced downwards over the head ; sides with a short conical 

 tubercle. Elytra broadly ovate, reticulately foveate, and with the 

 usual three rows of tubercles, but rather less prominent than in the 

 other species, the outer row containing eight tubercles.

 Museum (?). 



H. proles, Kolbe, is evidently the Eastern representative of this 

 species, and perhaps doubtfully distinct from it, as the Ehodesian 

 examples of the former rather serve to link the two forms. The 

 chief distinctive characters in omissus are the comparatively shallow 

 emargination of the dorsal anterior lobe of the thorax and the quadri- 

 foveate rostrum. The description of foveiceps, Quedf., agrees very 

 exactly with Pascoe's type. The mesosternal tubercle is slightly 

 developed.
