46 Mr. G. R. Waterhouse : Contributions to the Entomology 



gular tubercles are observable on the surface, and on the apical 

 third are four (two on each and one above the other) which are 

 larger than the rest ; beyond these there are some small irregular 

 rugae, somewhat oblique but nearly transverse, which run in as it 

 were from the lateral keel. 



Entomoderes cellulosus, Lacord. Appears to me to be a small 

 specimen of Ent. Erebi. Beyond the size, it differs only in having 

 the network-like raised ridges on the elytra rather more strongly 

 marked. Length 9 lin. ; width 4^ lin. 



Entomoderes satanicus, Lacord. 

 Ent. niger, infra fulvescenti-albopulverulentus, partibus superioribus, 

 at parce cinereo-pulveralentis, nisi apud elytrorum apicem, ibi pul- 

 vere notas duas per sulcum carinse lateralis et marginem externum 

 ductas, effeciente : thorace cum angulis lateralibus valde prominen- 

 tibus, apice acute, retrorsum extrorsum spectante, costis duabus 

 superne et post has costa brevi centrali ; elytris supra fere planis, 

 cum tuberculis parvulis et lineis elevatis in mode irregulariter re- 

 tiformi dispositis. — Long. corp. 7J lin. ; lat. 3f lin. 

 Considerably smaller than either of the preceding species : 

 covered throughout as it were with an ash-coloured dust ; on the 

 under parts and on the antennae this powder-like substance hides 

 the black ground-colour of the insect, but the upper parts are 

 only partially hidden by it ; it is more dense in parts ; along the 

 lateral keel it forms a grayish line, and on the apical portion of the 

 elytra two irregular markings, one on each elytron commencing 

 broad and dentated about the apical third of the elytron, and be- 

 coming gradually narrower to the apex. The thorax is very short, 

 and the lateral projecting points are very prominent and acute, 

 but, as in Ent. Draco, the posterior angles are not produced, — they 

 are in fact right angles ; the anterior angles are produced in the 

 form of a narrow process rounded at the point ; on each side of 

 the central dorsal line, which is slightly raised on the hinder part 

 of the thorax, are two raised lines as in Ent. Erebi, but they are 

 rather more prominent than in that species. The elytra are 

 sculptured as in Ent. Erebi, excepting that there is scarcely any 

 trace of the fii'st inner costa, which is observable in the basal por- 

 tion of the elytra of that insect : the lateral keel is divided into 

 two ridges by a longitudinal groove, and is very rough ; towards 

 the apical portion of the elytra, the keel is provided with acute 

 tubercles. 



Perhaps I should be rendering these notes more useful by add- 

 ing a brief description of the Ent. Erebi (the type of the genus), 

 and thus completing the characters of the species, so far as they 

 are at present known.
