Genera and Species of Coleoptera. 53 



I have not placed this genus among the Melandryidae without 

 hesitation, on account of its antennary orbits, and its acetabula 

 closed behind ; on the other hand, its parapleural, distinct from the 

 pronotum, make its location in any other family still more difficult. 

 Except the comparative shortness of the maxillary palpi, it agrees 

 •with the Melandryidae in most of the characters given by M. Lacor- 

 daire, according also in form with some of its genera, without, how- 

 ever, being related to any of them. Like Tetratoma, it has the 

 antennae terminating in a club, but only composed of three joints. 

 In the drawing the maxillary lobes are much too large, compared to 

 their palpus. 



Elacatis delusa. (PI. II. fig. 5.) 



E. griseo-testacea, punctulata ; elytris fasciis tribus dentatis, maculaque 

 basali nigris. 



Hah. Borneo (Sarawak) ; New Guinea (Dorey). 



Greyish-testaceous, finely punctured, a short setulose hair arising 

 from each puncture ; prothorax with three or four very minute teeth at 

 the side, and a shallow transverse impression near the base ; scutellum 

 long and narrow ; elytra with three black, toothed bands, the first often 

 interrupted or replaced by a few spots ; a patch of the same colour, also 

 sometimes broken up into spots, at the base near the scutellum ; 

 antennae and legs testaceous-yellow, more or less clouded with brown ; 

 body beneath ferruginous, slightly tomentose. Length l£-2 lines. 



My New Guinea specimen agrees perfectly well with those from 

 Borneo ; but they all vary a little in colour, some being darker than 

 others, and the black band and scutellar patch being more or less 

 interrupted. A second species, and a much finer one, from the 

 Moluccas, is in the collection of W. W. Saunders, Esq. 



Biophida [Melandryidae?]. 

 Head moderately long, tumid in front, suddenly contracted behind into a 

 narrow neck. Eyes distant, lateral, renifomi. Antennas arising close 

 to the eye, filiform, half as long as the body, 11-jointed; the second 

 very short, the rest subequal. Labruni transverse, inserted below the 

 line of the front. Labial palpi filiform ; the maxillary elongate, with 

 the last joint narrowly securiform. Prothorax depressed, semicircular, 

 as wide as the elytra behind, its parapleurae distinct. Elytra depressed, 

 rather broader behind. Legs moderate ; anterior and middle coxae con- 

 tiguous, the former conical and elongate ; tibiae spurred ; tarsi slender, 

 the first joint of the four posterior as long or longer than the rest 

 together, the penultimate bilobed ; claws undivided, strongly toothed 

 beneath. 



This is another of those puzzling genera, of which there are so
