Species o/Curculionidse /rom Africa, 385 



The female genitalia (text-fig. 3, «) are remarkable for the 

 great development and flattening of the apical palp-like 

 organs (cf. text-figs. 5 and 7), which is no doubt correlated 

 with the absence of any elongate extensile ovipositor, the 

 vagina not being differentiated from the bursa copulatrix. 



Subfamily Esttibbbininj!:. 



Rhytirrhinus lohaticollis, sp. n. (PL XIII. figs, 7, 8.) 



^ ? . Black, uniformly clothed with earth-brown scaling. 

 Head completely concealed from above by the anterior 

 thoracnc lobe; the forehead excavated, with a high squamose 

 fringe above the eyes, the vertex with two short longitudinal 

 ridges foi-med of densely packed stout seta3, and a row of 

 numerous similar setjx? between tliem and the lateral mar- 

 gin ', eyes rather coarsely facetted, serai-ovate, the posterior 

 margin almost straight ; the gular area very finely aciculate, 

 and not transversely carinulate. Rostrum with a very broad 

 and deep median furrow^ occupying almost the whole dorsal 

 width and bounded laterally by a ridge bearing a dense 

 mass of erect scales ; an almost equally broad and deep 

 lateral furrow above the scrobe, the latter densely squamose 

 throughout ; the epistome convex and without any defined 

 boundary. Antenme comj)aratively long and slender; the 

 scape just reaching the eye, slender in the basal two-thirds, 

 gradually elavate at the apex, and bearing the usnal erect 

 setie ; the two basal joints of the funicle longer than the 

 rest together, joint 1 as long as the club, 2 a^i long as 3-5 

 together, 3 elongate, 4-6 bead-like and a little longer '♦iiau 

 broad, 7 transverse. Prothorax a little longer than broad 

 (9:8) ; the dorsum concave, with all the margins except 

 the base stronglv raised ; the anterior portion produced into 

 a long bioad lobe considcnabiy exceeding the head, its apex 

 deeply sinuate, and its edges bearing clumps of matted 

 erected scales ; the lateral margins similarly produced, but 

 the lobes shorter and broadly truncate, or with the posterior 

 clump of scales higher than the anterior one ; in the middle 

 of the base two short high longitudinal ridges of matted 

 scales, and on each side of the disk a similar transverse, 

 slightl}' oblique ridge ; the centre of the anterior lobe, 

 which is the deepest part, set with numerous erect broadly 

 spatulate scales ; the shallow reticulate punctation hidden 

 by earthy indumentum, and more readily visible on the 

 [)leurre, on which there are two small prominent tubercles 

 bearing tufts of nuitted scales. Elytra with four tubercular
