Sub-fam. RHOGADINAE. 

 Colastes javanus, n. sp. 



$ 5 mms. long. Head and thorax smooth and shining, 

 only the metanotum rugose, abdomen dorsally rugoso-striate. 

 Ochraeeous, eyes, ocellar space, parapsides, metanotum and 

 abdomiDal tergites basally infuscated. 



. Head transverse, rather wide and thick in the middle, 

 eyes bulged and slightly emarginate within, ocelli arranged 

 in an equilateral triangle on the vertex, the members large, less 

 than one diameter from border of eye, a median furrow behind 

 reaches occipital margin, front flat and inclined to the face, 

 which is vertical but slightly receding, antennae broken, joints 

 1 and 2 stout, separated at base and fairly close to margin of 

 3* eye, the sockets large, almost tubereulate, mandibles stout, 

 cheeks less than half short diameter of eye and separated from 

 face by a distinct furrow. Pronotum fairly wide, the pleurae 

 much wider and concave, with a costate furrow in the con- 

 cavity, mesonotum convex, parapsidal grooves complete, con- 

 verging apically in a short longitudinal furrow, middle lobe 

 bulging, apical margin of scutellum and postscutellum angu- 

 late and carinate, disc of the former triangular, a large shallow 

 fovea at base and wide shallow costate grooves laterally, meta- 

 notum with two large semicircular areolae basally. Abdomen 

 elongate oval, depressed, 1st segment longer than wide, 2nd 

 and 3rd solidly joined, together longer than wide, a shallow de- 

 pression beyond the middle marking their separation, 4th, 5th 

 and 6th transverse, 7th and 8th small and inconspicuous, hind 

 margin of all the segments swollen and carinate. 



Wings hyaline, stigma broad lanceolate, radius emerging 

 before middle, 1st abscissa less than half 2nd, recurrent nervure 

 interstitial, subdiscoidal joining the discoidal below the middle 

 and the latter broken, nervellus postfurcal.

Heterogamoides, gen. nov. (type muirii). 



Eyes and ocelli large, the latter hardly farther from 

 occiput than margin of eye, cheeks small, palpi flat but not 

 expanded, parapsidal grooves indistinct, transverse groove at 

 base of scutellum sex-foveate, metanotum convex and medially 

 longitudinally carinate, abdomen elongate oval, depressed, 1st 

 segment longer than wide, 2nd quadrate, 3rd and following 

 transverse, tergites medially longitudinally carinate and longi- 

 tudinally striate to middle of 3rd segment, transverse impres- 

 sion between 2nd and 3rd quite distinct, ovipositor short, 

 stigma of front wings broad lanceolate, radius emerging from 

 middle, 1st and 2nd abscissae subequal, 2nd cubital cell more 

 than twice as long as wide and parallel-sided, recurrent ner-
