(3) il/. callghtea sp. nov. 



Dark brown; the coxae of hind legs yellowish, tegmina and wings 

 brown with dark veins. Male pygophor very large; ventral edge 

 sinuate and slightly emarginate, lateral edges curved and turned 

 slightly inward, medio-ventrally there projects a plate which in ventral 

 view is thin with two small projecting points at apex, in lateral view 

 wide at base and curving off to thin apex; styles a little longer than 

 median process, slightly swollen in middle, bifurcate at apex, the ends 

 of the bifurcations rounded; anal segment very large, projecting well 

 beyond styles, in dorsal view flat, subovate, the anus at apex, the edges 

 turned down and apically meet beneath anus, thus forming a large 

 concavity on the ventral side of segment, in which lies the large 

 and complex penis.

'; (4) M. neocaUginea sp. nov. ( $ ^ ) 



This differs from califnnea by the lateral keels of vertex and face 

 being yellowish. Male pygophor with a medio-ventral spine, lateral 

 edges evenly and roundly produced; anal segment not reaching to end 

 of styles, little longer than broad, in dorsal view subtruncate at apex, 

 where anus is situated, edges turned down thus forming a concavity 

 on ventral side; styles boomerang shape, narrowest at base, outer 

 edge concave inner convex. 



Length 2.8mm. ; tegmen 4.2nnn. 



LTab. Malay Peninsnla ; Mowong ( ?)• I have specimens of

 is possible that they are only light forms of caliginea.

Brown; apex of face, clypeus, legs and ventral surface of thorax

 with yellow over the clavus and across middle of cubitus, a crescent- 

 shaped dirty white mark over apex from radial to last median apical 

 veins. 



This species differs from the former four in having a median 

 longitudinal keel on vertex, and the transverse keel is v-shaped in
