t'. Upper surface wholly or in part opaque; 



tarsi short. [Subgen. Intybia, Pasc] . . Species 26-29 {(i-i). 

 bb. Anterior tarsi of c5' with joint 2 prolonged or 

 raised over the base of 3. [Subgeu. Di-

/■'. Upper surface shining; tarsi longer Species 29 {j). 



k'K Upper surface opaque ; tarsi short Species 29 (k-m). 



2 (a). Laius submarinus, sp. n. 



$ . Smaller, less elongate, and more shining than the ? of 

 the Malayan insect identified by me as L. (Paussus) flavi- 

 cornis, F., autea p. 325, the antennal joints 1 and 2 dif- 

 ferently shaped : bluish -green^ the elytra cyaneous, the 

 anterior margin of the head^ the labrum, palpi, and the 

 antennal joints 1-3, rufo-testaceous, the rest of the antennae 

 and the legs black ; cinereo-pubescent, the head and pro- 

 thorax densely, very finely, the elytra excessively minutely, 

 punctate ; head small, canaliculate ; antennal joint 1 

 shorter, more curved, and more dilated outwards, and 2 

 relatively shorter, broader, and more rounded on its inner 

 aspect, than in L. flavicornis ( $ ) ; prothorax transverse, 

 less rounded at the sides ; elytra comparatively short, parallel. 



Length 3^ mm. 



^. Anteunse (figs. 9, 9 «) with joint 1 long, curved, com- 

 pressed, broadly truncato-dilatate in its outer half externally ; 

 2 enormously dilated, transverse, subquadrate as seen from 

 its upper aspect, emarginate and deeply concave on its basal 

 aspect, the strongly reflexed inner and outer margins pro- 

 duced into two converging blunt processes at the base above. 

 Anterior femora hollowed at the apex beneath ; anterior 

 tibiae curved, greatly swollen at about the middle, convex 

 externally, sinuato-excavate at the base within ; anterior 

 tarsi simple. 



Hah. Philippines, Mindanao (Setnjjer : cT ? )^ Dapitan, 

 Mindanao {Baker: No. 16160: ? ). 



One (^ and two ? ? seen; others are presumably con- 

 tained in Mr. Baker's collection. Certainly distinct from 

 L, fiavicornis, several ^ and ? specimens of which are 

 before me. 



" Lives in cracks and holes of sandstone that reach pretty 

 far out into the sea, quite covered during the fiood-tide 

 but dry during the ebb." {Semper.)
