cxxxiv Mr. E. Newman's 



tant at the base, seated on small but distinct protuberances, and 11 -jointed : the eyes 

 are large, round, lateral, distant, prominent and black ; the entire epicranial region, 

 including the tubercles on which the antennae are placed, is black, punctured and 

 shining ; the face below the antenna? is ferruginous, the same colour also pervading 

 the mouth and its appendages, the labium excepted, which is black and highly gla- 

 brous ; the antennae require a more minute description, and I cannot avoid expressing 

 the fear which I entertain of being unable to convey in words a correct idea of their 

 anomalous structure : the 1st joint is long, slender at the base, stouter towards the 

 apex, porrected directly in front of the head, and somewhat curved inwardly, so that 

 the extreme point of the curvature approaches and nearly meets the corresponding 

 point of the 1st joint of the other antenna, this joint is entirely black and shining ; the 

 2nd and 3rd are severally half the length of the 1st, simple, straight, and subcylindri- 

 cal or deviating only from a cylindrical form in being slightly incrassated externally ; 

 they are of two colours, black and pitchy red, longitudinally divided ; the 4th has the 

 same general character, and the same distribution of colour, but is shorter and stout- 

 er ; the 5th is of nearly equal length with the 4th, but flattened out on one side into a 

 large rounded lobe ; it is black, with the exception of a small ferruginous portion at 

 the base ; the 6th is not more than half the length of the 5th, but is flattened and di- 

 lated in the same way, as far as its length will permit, it is entirely black ; the 7th is 

 rather longer than the 5th, dilated and hollowed into a kind of basin, the bowl whereof 

 is white and the rim black, this joint has much the appearance of a mounted lens ; the 

 8th is not more than half the length of the 7th, it has a small dilated and flattened 

 portion, which is white, while the shaft is black ; but the dilated portion in this is very 

 inferior to that in either of the three preceding joints ; the 9th and 10th are short, ob- 

 conical and pitchy ; the 11th is longer, pitchy, and somewhat sausage-shaped. 



Mouth : — the labrum is rather large, nearly square, but having the anterior mar- 

 gin rounded at the angles and depressed or notched in the middle : mandibles arcu- 

 ate, hooked and bifid at the apex, the two points being similar, closely approximated 

 and acute ; the inner margin of the mandible is increased, and its concavity filled, by 

 a tumid, slightly ciliated, coriaceous or semimembranaceous lobe : maxillae having the 

 three constituent terminal portions distinct and separate ; the maxipalpi are large and 

 4-jointed, the basal joint very minute, the 2nd three times the length of the 1st, and 

 thickened apically, the 3rd shorter and more robust than the 2nd, the 4th fully equal 

 in length to the 2nd, dilated, somewhat but very indistinctly triangular, the apical 

 margin obliquely truncate and slightly rounded ; galea very much shorter than the 

 palpus, jointed and elbowed near the base, the apical portion somewhat linear, much 

 longer than the basal portion, the apex incurved and thinly beset with incurved hairs : 

 labium with the anterior margin rounded, but depressed in the middle ; ligula divided 

 by a median notch into two large spreading rounded lobes fringed with cilia ; labi- 

 palpi shorter and smaller than the maxipalpi, 4-jointed, the 1st, 2nd, and 3rd joints 

 short and robust, the 4th longer, stouter towards the apex, where it is obliquely rotun- 

 dato-truncate. 



Prothorax rather narrower than the head, rather longer than broad, indistinctly ob- 

 cordate, being evidently swollen towards the anterior and narrowed towards the poste- 

 rior margin ; its dorsal surface is somewhat uneven, its colour bright ferruginous and 

 shining. 



Elytra rather broader than the prothorax, long, narrow, severally rounded at the 

 apex, slightly dehiscent, extremely thin, flexible, nearly black, covered sparingly with
