There are numerous ? ? of this insect in the Cape Town 

 INInseum, and a pair of the type-form, and tliree c? S of the 

 dark variety, in the British Museum. These latter agree 

 perfectly in the structure of the head w ith a typical (^ , and 

 they are therefore referred to the same species. Erichson's 

 tlescription was based upon a specimen of that sex. The type 

 has two rather broad white fascise on the elytra — one median, 

 not reaching the suture, the other extending along the apical 

 margin, — which are much narrower, and the apical one some- 

 times wanting, in the var. nigricollis. 



2. Chalicorus flavofasciatus, sp. n. (PI. IV. fig. 16, 

 head and prothorax in profile, (J .) 



J . Elongiite, rather narrow, shining, finely, very sparsely 

 pubescent ; brilliant cyaneous, the antennae (the testaceous 

 joints 2-4 excepted) and legs black, the elytra witii a coin- 

 l)lete, outwardly widened, testaceous submedian fascia ; the 

 surface-puncturing sparse and very tine. Head broad, ti'ans- 

 versely triangular, sulcate around the very proinineut eyes 

 in front, and w ith a deep, arcuate, frontal excavation, in the 

 centreof which is a rounded, transverse, horn-like prominence 

 projecting backward from the epistoma : antennae long, 

 filiform, rather stout, joints 2 and 3 short, broad, transversely 

 subquadrate, subequal in length. Prothorax elongate, 

 abruptly constricted and narrowed posteriorly, the anterior 

 ])ortion strongly, longitudinally gibbous on the disc and 

 deeply sulcate laterally, the transverse basal groove also deep, 

 the base itself raised and obsoletely bituberculate. Elytra 

 w idened posteriorly, at the base as broad as the head, deeply, 

 transversely depressed before the middle, and also hollowed 

 along the suture anteriorly, the apices conjointly rounded. 

 Anterior tarsi 5-jointed, joint 4 small.
