PHYTOPHAGOUS AND PAEASITIO HYMENOPTBRA. 139 



Lissotheronia, gen. no v. 



Abdominal segments broader than long, perfectly smooth, shin- 

 ing, impunctate ; the first segment bituberculate at the base. 

 Median segment strongly, closely, transversely striated, the spiracles 

 about three times longer than wide, broader below than above. 

 Eyes large, incised on the inner side ; malar space smaU. Clypeus 

 clearly separated, its apex obHquely depressed. Transverse median 

 nervure in hind wings broken distinctly above the middle. Trans- 

 verse median nervure received beyond the transverse basal. Disco- 

 cubital nervure broadly rounded, unbroken. Claws simple ; tarsi 

 thickly spinose. Antennae slender, longer than the body, the last 

 joint nearly as long as the preceding two united. 



This genus might be mistaken for a Pimpla, from which, however, 

 it can be readily known by the perfectly smooth, shining abdomen. 

 In Dr. Ashmead's system it would come in near AUotheronia, which 

 may be known from it by the metathorax having a strong transverse 

 apical area, with the upper angles dentate or tuberculate, the whole 

 thorax, too, being " closely, finely, rugosely punctate " except for a 

 spot on the middle of the mesopleurse. It has the metanotum closely 

 transversely striated as in Lissopimpla, having also the smooth 

 abdomen of that genus ; but otherwise is readily separated from it 

 by the absence of parapsidal furrows and of a tooth on the hind 

 femora. 



54. — Lissotheronia flavipes, sp. nov. 



Black, shining, except the median segment which is closely striated, 

 the pleurae more closely and obfiquely than the dorsal surface ; the 

 legs yeUow, except the fore coxae in the middle below, and the 

 four hind coxae and trochanters, which are black ; wings hyaline, 

 shghtly suffused with yellow. A spot on the scutellum in the centre, 

 a curved one on the post-scutellum, and one on the base of the 

 tegulae are yellow. The depressed apex of the clypeus is smooth and 

 shining ; the raised upper part sparsely punctured. Face closely 

 punctured ; the sides of the lower part roundly convex. Tarsi 

 spinose, much longer than the tibiae. Sternum and under side of 

 coxae thickly covered with fulvous pubescence, ?. 



Length 15 mm. ; terebra 4 mm. 



Pundalu-oya, February. 



55. — Charitopimpla annulipes, sp. nov. 

 Plate B, fig. 9. 



Black ; antennal scape except above, tegulae, hind edge of prono- 

 tum, and palpi, yellow; the apex of the abdominal segments narrowly 

 yellow ; the yellow hnes dilated at the sides and tinged with rufous
