460 Four new species of the Coleopterus Family 



podice, elytrorumque plaga magna communi, piceis ; abdo- 

 mine elytrorumque marginibus, tibiis, tarsisque, castaneis. 

 Antennarum clava obliquo-triangulari, basi emarginata in 

 spinam longiorem externe producta, postice late impressa, 

 cavamine rugoso. Long 3/20 poll. 



This species is so nearly allied to Paussus rufitarsis of 

 Westwood, the habitat of which is unknown, that, beyond 

 question, that insect is to be referred to the list of Indian 

 species. I shall note the differences observable on a compari- 

 son of the two forms, as I proceed with the description. The 

 antennae in P. Baconis are lengthened, oblique, triangular, 

 instead of being elongate-globose, and fall off more suddenly 

 from the base to the apex, which forms an obtuse angle. 

 On the inner basal side there is a much deeper emargination 

 between the articulation of the joint and the spur, which is 

 more produced than in rufitarsis. The anterior margin is 

 acute, and the hinder face has a larger and deeper impres- 

 sion, sulcated longitudinally in the centre, and crossed by 

 three raised ribs. Four obsolete ribs are apparent on the 

 upper side of the disk near the superior margin ; the inner 

 side is convex. 



The clypeus is deeply emarginate in front, and a strong 

 sulcus runs from it to the back of the head, widening con- 

 siderably, and being more depressed behind the eyes, which 

 are very minute, black, uniform when viewed laterally, and 

 wide apart. The space between the eyes and central chan- 

 nel is much raised, and, somewhat in advance of the eyes, 

 presents on each side a large and deep rounded depression, 

 and immediately at the top of the elevation, between the 

 eyes, is a small rounded depression on each side. In rufi- 

 tarsis the central depression is isolated, instead of communi- 

 cating with the emargination of the clypeus, by a deep sulcus. 



The fore-part of the bipartite thorax which is livid-suc- 

 cineous, is obtusely angled at the lateral extremities, and 

 depressed in the centre, the ridge is rounded, not angular, 

 and it is about the same breadth as the head. The piceous
