of the Paussidte, and notice of a fifth species, 465 



The specimen was taken in February 1845, by Dr. J. F. 

 Bacon, at Moradabad in Rohilkhund, to the north of the 

 river Ganges. It was drowned in a pool of water. 



4. — Platyrhopalus intermedius, nobis. 



P. rufo-castaneus, elytris angustioribus, singulo plaga 

 elongata triangulari irregulari ad latus externum praedito. 

 Antennarum clava mediocri, subrotundato-quadrato, margine 

 postico undulato, versus basin late inciso, lingula acuta armato. 

 Capitis fronte rotundato, clypeo minime emarginato. Tibiis 

 latis oblique truncatis. Long 3/10 poll. 



Hab. — Saharunpore. 



This species unites characters of three different forms, viz. 

 P. angustus, P. nentidens, and P. Westwoodii. With the first 

 it agrees in habit, but differs from it and from the third, and 

 agrees with the second in having no emargination of the 

 clypeus. The form of the antennae is more like P. West- 

 woodiiy but on a smaller scale, and like that species, the hinder 

 margin of the clava is sinuous, a character not to be found 

 in the others. The hinder part of the prothorax has some 

 shallow transverse furrows, not very conspicuous ; the elytra 

 have each a single lateral patch, which is not removed so 

 much towards the base as in the typical specimen of P. an- 

 gustus, but is rather in shape and situation like the lateral 

 patch which shares the elytra in P. Westwoodii with a basal 

 and a terminal spot. 



This insect was captured on the 28th March 1845, at 

 night. It flew to a light in a small bungalow on my grounds 

 at Saharunpore, the capital of a district at the head of the 

 Doab, and was subsequently obtained by me from the 

 captor. 



I might here add the description of a new form partaking 

 of the characters of Ceratoderus and Pentaplatarthrus, two
