Westwood (I. c.) proposed his name P, acutidens for an 

 imperfect specimen without elytra, legs, or abdomen. This 1 

 specimen is at present in the British Museum, as the type 

 of the species, with the body and the elytra of a species of 

 the phytophagous genus Lema (of the same colour as the front 

 parts, but strongly punctured) appended to the pronotum to 

 make up a perfect insect ! The single type of P. angustus is 

 badly set and not in good condition. It is very probable that 

 var. acutidens and var. major are the same insect, but I have 

 not seen a specimen of the latter ; the characters of the club, as 

 compared with P. denticornis, are very distinct. 



In the Indian Museum there is a dark variety from Bengal, 

 Purneah District, and a varying series from the following 

 localities : — 



Madras : Dumagndiem, Godavari ; Bengal : Purneah Dis- 

 trict ; United Provinces : Chandan Chowki, Dehra Dun ; 

 Kashmir: Jhelum Valley ; Assam: Dunsiri Valley.

Platyrhopalus intermedins, Benson, Calcutta Journ. Nat. Hist, vi, 

 1846, p. 468; Westwood, Trans. Ent. Soc. Lond. v, 1847, p. 25. 



Rufo-castaneous, with the elytra rather narrow, each with an 

 elongate irregular triangular patch at the sides ; antenna? with 

 a moderate-sized, somewhat roundly-quadrate club, with the 

 posterior margin undulated, broadly incised at the base, with 

 the projecting tooth sharp ; the elypeus is not, or very slightly 

 emarginate, and the tibiae are broad and obliquely truncate. 



This species appears to have the incision and tooth of the 

 club of P. angustus, and the uneven margin of the club of 

 the antenna? of P. ivestivoodi ; the coloration of the elytra is 

 different from that of the latter. 



Length 7}j-9 millim. 



United Provinces : Saharunpur (Benson). 



It is very probable that this is a form of P. angustus. 



22V>. Platyrhopalus westwoodi, Saund. 



Platyrhopalus icestwoodi, Saunders, Trans. Ent. Soc. Lond. ii, 1835 ( 

 p. 84, pi. 10, fig. 5 ; Westwood, Trans. Linn. Soc. Lond. xix ? 1842, 

 p. 51 ; id., Arcan. Ent. ii, 1845, p. 78, pi. 68, %. 2. 



Slightly smaller, on an average, than P. denticornis, and 

 distinguished from it by the wider incision and much sharper 

 tooth at the base of the club of the antenna?, by the longer 

 pronotum, and by the colour of the elytra, which seems fairly 

 constant, being rufo-castaneous with a common dark patch, 

 usually more or less triangular, at the base, a large patch at 

 the side of each, diminishing in length towards the suture
