near the suture. The body beneath is of the same brown colour, 

 densely pilose, with a long white lateral fascia reaching from the base 

 of the head, where it is broadest to the base of the mesosternum, 

 where it is pointed ; in some specimens this mark is only on the meso- 

 sternum, in others it is absent. Long. 12 lines, max. lat. 3f lines.

Plectrogaster jordani, sp. n. (fig. 2). 

 Elytra brownish black, piceous, coarsely and thickly punctured, and 

 having on each elytron four longitudinal carinate lines, which terminate 

 2 lines from the apex. The scutellum is rounded, tongue-shaped. Pro- 

 notum densely pilose ; in the centre is a brownish black longitudinal 

 fascia reaching from the head to the scutellum ; on each side of this is a 

 rich reddish fascia, also reaching from the head to the elytra, and on 

 each side of this red mark is another brownish black one reaching from 

 the head to just below the pronotal tooth, which is reflexed backward. 

 The head is red, pilose. The antennae are blackish brown, beautifully 

 pectinate ; the basal joint is red, small at its insertion and thickened 

 at its apex, which is blackish ; the lamellae, nine in number, arise 

 from the joints of the antennae and are nearly equal in length (3 lines), 

 except the first, which is a little shorter ; the joints of the lamellae 

 form a serrature on the under side of antennae. The body beneath and 

 the legs are light shining reddish brown ; the joints of legs are blackish. 

 The middle and hind femora are pubescent, and the hind femur has 

 a longitudinal groove underneath ; the tarsi are blackish brown. Long. 

 20 lines, max. lat. 6 lines.

This insect comes very near to P. pectinicornis, Waterhouse, 

 a female of which is figured in his ' Aid ' ; but it differs in some 

 important respects. P. pectinicornis has blacker elytra, and the 

 pronotum and head are wholly black ; the femora are yellow, 

 and black at their insertion, with black tibiae and tarsi. The 

 elytra and pygidium are pilose. 



I am indebted to Mr. Horace Knight for the wonderfully fine 

 drawings for the figures of the three beetles above described.
