t'. Upper surface wholly or in part opaque; 



tarsi short. [Subgen. Intybia, Pasc] .. Species 26-29 (rt-t). 

 bh. Anterior tarsi of S with joint 2 prolonged or 

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

.7^. Upper surface shining; tarsi longer Species 29 [j). 



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

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

 anterior margin of the head, the labrnm, palpi, and the 

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

 and the legs black ; ciuereo-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. flavicoruis ( ? ) ; prothorax transverse, 

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



Length 3^^ mm. 



^ . Antennae (figs. 9, 9 a) with joint 1 long, curved, com- 

 })ressed, 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 

 asj)ect, 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. 



Hab. Philippines, Mindanao (Semper : c? ? ), Dapitan, 

 Mindanao {Baker: No. 16160: ? ). 



One c? and two ? ? seen; others are presumably con- 

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

 L. flavicornis, 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.)
