on the base of the mesopleurae in the centre, a triangular mark under the 

 hind wings, and the apices of the basal 2 abdominal segments broadly and 

 of the others more narrowly, pale yellow. Legs red, the 4 anterior coxae 

 and trochanters distinctly, their tibiae and tarsi less distinctly tinged with 

 yellow ; the hind knees, apex of hind tibiae and the tarsi, black. Wings 

 hyaline, the stigma and nervures black, the areolet small, almost square. $?. 



Length 7 ; terebra nearly 2 mm. 



Deesa. October. 



Antennae longer than the body, thickened towards the apex ; joints 9-13 for 

 the greater part white. Middle of front below the ocelli coarsely irregularly 

 reticulated-striated ; the part immediately below the ocelli stoutly, obliquely 

 striated ; there is a smooth line in the middle of the punctured part, which is 

 narrowed roundly below and does not reach to the antennae. Face and clypeus 

 strongly, closely punctured and covered with white pubescence. Pro- and 

 mesothorax strongly closely punctured, more or less reticulated ; the middle of 

 scutellum, except at the base and the apex, broadly impunctate. Base of meta- 

 notum strongly punctured, the punctures clearly separated, the sides between 

 the keels stoutly obliquely striated, more or less reticulated, the central part 

 smooth at the base, the rest with large, separated punctures, the apical slope 

 closely, distinctly reticulated ; areola deep, shining, wider than long. Pleurae 

 and sternum opaque, closely, regularly, distinctly, but not coarsely punctured. 

 Basal 2 segments of abdomen closely, somewhat strongly punctured, the 3rd more 

 finely punctured, the others smooth. The metanotal teeth are not prominent. 



The genus Cratocryptus, Cam. was described in the Journ. St. Branch Roy. 

 As. Soc. 1905, p. 142, on a species from Borneo. It may be separated from 

 that here described thus : — 



Mesoplenrse immaculate, middle of face black, metanotal spines 



distinct, hind tarsi white -..viaculiceps Cam. 



Mesopleurse with a large yellow mark; middle of face yellow, 



metanotal spines indistinct, hind tarsi black. rufipes, n. sp. . 



Melcha nursei, sp. nov. 



Ferruginous, a line on the inner orbits, the base of pronotum, post-petiole, 

 the 4th and following segments of the abdomen above, white ; the antennal 

 scape red, the flagellum black, with joints 9-11 white ; legs coloured like the 

 thorax ; the 4 anterior tibiae white behind ; the posterior knees, tibiae and tarsi 

 black ; the basal fourth of the tibia? white ; wings hyaline, the stigma and 

 nervures black, the former with a white spot at the base. $ . 



Length 8-10 mm. ; terebra 2 mm. 



Deesa. February to December. 



Face and clypeus closely, somewhat strongly punctured ; the front irregular- 

 ly obliquely striated above, the striae running into reticulations ; there is a 

 stout keel down the middle ; ocellar region rugosely punctured ; the orbits are 

 sparsely punctured. Mandibular teeth black. Palpi pale testaceous. Meso- 

 notum closely, strongly punctured ; faintly striated along the furrows ; the
