Coleopterous Familij Dermestidae. 449 



This is very closely related to ..4. ocellifer, Blackb., with 

 which alone it shares the peculiar oblong- form, anteriorly 

 elevated pronotuni, and abruptly clubbed 11-jointed antennae. 

 ]t differs, however, in its more elongate outline and much 

 smaller and more setiform scales. Tlie pattern formed by 

 these is very variable but lilce that of A. ocellijer. The 

 front and hind margins of the pronotum are clothed with 

 light scales, and these also form uj)on the elytra an anterior 

 ring-, an irregular median band and a posterior ring. Tiiese 

 markings may become split up into small scattered patches, 

 and brown scales may appear in addition to the black and 

 white ones. 



Genus Apsectus. 



Trinodes niexicamis, Reitter, is probably Apsectus hijsfrix^ 

 Sharp, described twenty-two years later, and in that case will 

 become Apsectus mexicaniis, Reitt, 



This genus, wliich differs from Trinodes in not having the 

 niesosternum channelled for the recej)li()n of a narrow pro- 

 steiiial process (which process is therefore also absent), is not 

 confined to the Western Hemisphere, as might be supposed 

 from the Catalogue. It; is probable, that numerous Oriental 

 species exist. One at least of those at present referred to 

 Trinodes must be transferred to it. This is T. hirtel/us, 

 Walker, in which the prosternum is very short and excised 

 behind and the mesosternum entire and rounded in front to 

 fit the pioiternum. 



Closely allied Oriental forms are the following, while 

 another from Australia is yet undescribed : — 



Apsectus iota, sp. n. 



Parvus, late ovatus, pronoto baud augusto ; prosterno rectangular], 

 postice recte truncate, mesosterno lato, autice fere recte trun- 

 cato ; antennis gracilibus (? maris), clava fusiformi, bi-articulata, 

 articulo peuultimo transverse, ultimo ovali, quam prtecedenti 

 quadruplice longiori.

Three specimens were taken by Mr. F. Muir amongst an 

 important collection of Coleoptera from this small Malayan 

 island. 



It is a species exceedingly like T. MrteJlus, Walker, in 

 size and general appearance, but rather more broadly oval, 

 the pronotum especially being less narrowed. In the relation 

 of the parts of the sternum it is also similar. As in A. hir- 

 tellus, the antenna (of the presumed male) ends with a large
