12 Mr. E. T. Higgins ow Ommatomenus. 



''Genera/' vol. viii, p. 71, as necessary for the reception 

 of AcanthopJwrus megalops, described by Mr. Adam White 

 in the first part of the British Museum Catalogue of 

 Longicorns; this is a fine insect^ from Fernando Po, 

 which, I have satisfied myself from examination of the 

 type in the British Museum, with the valuable aid of 

 Mr. Charles 0. Waterhouse, is congeneric with the new 

 species described below. 



Ommatomenus seeicatus, n. sp. (PI. II. fig. 1) . 



(J . Long, (mandib. exclusis) 29-34 lin. 

 Elongato-ellipticus, paulo convexus ; saturate casta- 

 neus, antennis basi nigris. Caput crebre subtiliter 

 punctatum ; fronte concava, punctata, sericeo-fulvo- 

 pubescente. Thorax supra paulo insequalis, subtiliter 

 punctatus, dense sericeo-fulvo-pubescens; disco an- 

 tico spinisque nudis. Scutellum pentagonum, in me- 

 dio subtiliter punctatum, marginibus laavibus. Elytra 

 ante medium paulo rotundato-ampliata, apicem versus 

 angustata, angulis suturalibus breviteracuto-spinosis, 

 supra subtiliter coriacea, opaca et punctulata, hu- 

 meris punctato-rugosis ; plagis confluentibus sericeo- 

 fulvis ornata. Sterna omnia dense sericeo-fulvo- 

 pubescentia; abdomen nudum, nitidum, segmento 

 ultimo transverse, late emarginato. 

 The body is of an elongate elliptical shape, dilated 

 behind the middle of the elytra, and very moderately 

 convex ; the colour is dark chesnut brown, with the basal 

 part of the antennae black. The head is finely and closely 

 punctured, with the front concave and clothed with silky 

 fulvous hairs: the hind part of the crown has not the 

 well-marked ridge which distinguishes Ommatomenus 

 megalops (White) . The thorax is a little uneven above, 

 and very finely punctate, not rugose-punctate, as in 0. 

 megalops. The sutural angles of the elytra are furnished 

 with a short acute spine ; above, the elytra are of a 

 leathery texture, and marked with numerous very fine 

 punctures ; there are a few coarser punctures near the 

 shoulders; the surface is opaque, and adorned with 

 numerous patches of fine silky reddish-fulvous pubes- 

 cence, which has a rich glow in certain lights. The 

 sterna are densely clothed with longish silky fulvous pile, 

 but the abdomen is smooth and shining.
