of tegmen, anterior apical margin tinged with red; wings hyaline 

 opaquely white with waxy secretion. Antenna reaching slightly 

 beyond eye. cylindrical, slightly constricted in middle, without 

 any projection or fork at base. 



Length 3.8 mm. ; tegmen 6 mm. 



Habitat : Alowong. 



(3) .1/. ijiniiacitlata sp. nov. ( 9 ). 



Structurally agreeing with type. Pale yellow, eyes brown, 

 gena tinged with red before eye, tegmina and wings hyaline, 

 opaquely white with waxy secretion, tegmina tinged with yellow, 

 yellow-veined. Hind margin of last ventral abdominal plate 

 roundly and bluntly jjroduced. 



Length 3.3 mm. ; tegmen 5.4 mm.

(3) M. pallida sp. nov. ( S 2 ). 



Antennae a little longer than head, a very short prong, or big 

 tubercle, projecting from the base. Hind margin of last ventral 

 plate of female angularly produced, centrally depressed or lipped 

 (like on a jug). General facies as in imuiaculata. 



Length 3 mm. ; tegmen 5 mm. 



Habitat : Teloc Ayer. 



(4) M. Hcxicornis sp. nov. ($). 



This has the general facies of the last two, but the prong of 

 the antennae is nearly as long as the main branch, the two form- 

 ing a horse-shoe-shaped organ. The genitalia separates it from 

 the male pallida, the genital styles being narrower and the anal 

 tube produced into a blunt, ventral, median process. 



Length 3 mm. ; tegmen 5 mm. 



Habitat : Pontianak. 



(5) M. rubella sp. nov. ( $ ). 



Head nuich more produced in front than in the type, prong of 

 antennae two-thirds the size of main branch, lying alongside of 

 it. Vertex, upper portion of gena, middle of pronotum and scu- 

 tellum, tinged with scarlet. Hind margin of last ventral plate 

 roundly produced. 



Length 4 mm. ; tegmen broken. 



Habitat : Amboina. 



Only one specimen with tegmina in bad condition.
