COLEOPTERA 



459 



This genus has the same relation to Cyrtostolits that Etipetinus has to Orthostolns. 

 It is distinguished from Ettpctimts by the condition of the wings, the metasternum at 

 the same time being shorter. On comparing several specimens of A. cxplanatus with 

 specimens of several species of Eupciimis, we find the posterior coxae slightly further 

 apart. 



The wings are of the same form as those of Cyiiostolus. The apical portion is 

 absent, the shape somewhat triangular, the outer margin slightly concave. 



The genus can be divided into two sections corresponding to those of Eitpetimis. 

 The first consists of the closely-allied A. niacrothorax and A. niedms. These have 

 narrow explanate margins to the elytra, which are as long in proportion to the whole 

 length as those of Eiipedints. Their wings are as long as, or slightly longer than, half 

 the length of the elytra. 



The second section consists of A. explanatiis, of which we have a large series, and 

 the closely-allied A. bi'cvis and A. pumilio. These have broad elytral margins and 

 shortened elytra. In eight specimens of A. cxplanatus which we have examined, the 

 wings are decidedly less than half as long as the elytra. H. S. 



(i) Apctinus inacroi/iorax, sp. nov. 



Sat latus, fusco-testaceus; marginibus, pedibus, antennarumque basi ferrugineis; 

 pedibus longis ; prothorace magno, elongato et lato, lateribus rotundatis, angulis poste- 

 rioribus argutis, disco quadri-impresso, crebre punctate ; elytris impressis, ad latera 

 explanatis, sulcis argutis punctatis, interstitiis transverse striatis ; abdomine sat crebre 

 punctato. Long. corp. 4^ mm., lat. corp. 2 mm., long, prothoracis circa i^ mm.

This remarkable species is characterised by the size of the prothorax (which is 

 considerably elongated, not strongly transverse, and is conspicuously broad, its greatest 

 breadth forming almost the greatest breadth of the body), and by the length of the legs, 

 the femora projecting distinctly beyond the edges of the body. The male supple- 

 mentary segment is rounded, slightly tapering towards the apex ; male pygidium 

 truncate with rounded angles ; female pygidium broader, subtruncate. 



The wings are reduced to the same form as those of A. explanatiis, with concave 

 outer margins ; but they are somewhat more than half as long as the elytra. Three 

 specimens.
