HYMEN OPT ERA OF SARAWAK. 147 



verse median nervure in hind wings broken almost in the 

 middle. Median segment large, without transverse keels ; its 

 apex with 2 tubercles and with an oblique, straight slope ; the 

 spiracles elongate. Petiole longer than the 2nd segment, its 

 base distinctly narrowed, the rest of equal width, roundly 

 curved in the middle. Legs stout, longish ; the basal joint of 

 all the tarsi longer than the other joints united ; fore tibiae 

 shorter than the tarsi, stouter than the others and distinctly 

 narrowed at the base. Temples moderately wide, rounded ; the 

 occiput margined, slightly, roundly incised. Parapsidal furrows 

 distinct to shortly beyond the middle. Apex of clypus project- 

 ing in the middle, the centre of the projection roundly incised, 

 with the sides rounded ; the apex below this is depressed, clearly 

 separated and transverse. Meta pleura? keel broad and dilated 

 at the base, narrowed at the apex. 



Comes near to Cryptoidens, Ashmead. The toothed clypeus, 

 the absence of transverse keels on the metanotum, the dark- 

 violaceous wings and the long metatarsus are 4 points which 

 make the genus easily recognised. 



Dinocryptus niger, sp. nov. 



Black; the inner eye orbits white in the middle ; the wings 

 uniformly dark fuscous-violaceous, with violet and purple tints 

 and highly iridescent, the stigma and nervi.res black. $ .

Hab. Kuching. April. 



Head closely and distinctly punctured ; the face roundly, 

 broadly dilated in the middle ; inner orbits distinctly margined. 

 Thorax closely and distinctly punctured, except on the pro- 

 pleurae which has the base smooth, the apex finely punctured. 

 The apical segment of the abdomen is smooth and shining ; 

 depressed in the middle at the base ; the others are closely 

 punctured, the punctuation becoming finer towards the apical seg- 

 ments. The 2nd segment is raised at the base, this part being 

 bounded by shallow, oblique furrows ; there are shallow trans- 

 verse furrows on the middle segments ; the penultimate is as 

 long as the preceding 3 united. Tarsi closely and shortly spined.
