Pascoe^s description of JB. fulvipes ( J ) is incomplete and mis- 

 leading : the very peculiar form of the anterior tibiae, the opaque lateral 

 patch on the elytra, and the row of setigerous impressions along each 

 dorsal interstice, were not mentioned ; the insect, in fact, is incorrectly 

 stated to be subglabrous, and its sex was not suspected. Numerous 

 males, including the type, have been examined, two from Santarem 

 having the prothorax rufo-testaceous and the elytra in great part 

 testaceous. The pallid coloration of the femora and tibiae seems to be 

 constant. A female from Ega, ferruginous in colour, with simple 

 antennae and legs, much smaller eyes, the opaque lateral patch on the 

 elytra wanting, and the setigerous impressions on the alternate interstices 

 mostly obsolete, almost certainly belongs to the same species. The 

 llabellate S -antenna is simply an exaggeration of the strongly obliquely 

 serrate corresponding organ of D. serraiicornis Miikl. 



22. — Diseiiia cisteloiJes, n. sp. 



O . Elongate, broad, unicli widened posteriorly, somewhat depressed, 

 dull above, sliiuing beneath; piceoiis or reddish-brown, the legs and antennae 

 usually ferruginous ; clothed with long, scattered bristly hairs. Eyes ex- 

 tivniely large, separated by a narrow line only. Antennae very long, strongly 

 serrate, joint 11 about equalling 8-10 united, curved, shallowly grooved and 

 asperate on its inner face. Prothorax transverse, slightly w'ider than the head,, 

 feebly rounded at the sides tanteriorly, the basal margin moderately prominent ;, 

 impressed with scattered intermixed coarse and fine punctures, canaliculate 

 anteriorly, and depressed in the centre at the base. Elytra long, broad, rapidly 

 widened to the middle, and there about three times the breadth of the pro- 

 tliorax, arcuately narrowed thence to the apex ; finely crenato-striate, the inter- 

 stices broad, rather convex, 1, 3, 5, 7, and 9 each with a series of scattered 

 mhuite tubercles followed by a small setigerous impression. Ventral segment 5 

 unnnpressed. Legs very long ; femora compressed, almost smooth, more or less 

 sulcate beneath, the intermediate pair with an opaque, elongate pad at about 

 the middle. 



Length 1]§- 13, breadth 4-4^ mm.

Twelve specimens, ajqiarently all males. A large Cistelifoi-m Lagriid, 

 differing from all the species of Disema described by Maklin * and Pic in
