HYMENOPTERA COLLECTED AT BUXA, BHOTAN. 5 



ICHNEUMONID^l. 

 Hadrocryptus tuberculatus, sp. nov. 



Black ; the face, clypeus, except for a small irregular mark in the 

 centre of the top above, exteuding on to the face, and a narrow line on 

 its apex, dilated in the middle, and extending on to the margined sides, 

 labrum, mandibles except the teeth, palpi, the inner orbits to the 

 occiput, the outer more broadly from near the top, where it is nar- 

 rowed, below extending on to the malar space ; pronotum at the base, 

 a line, narrowed behind, on the sides of the middle lobe of mesonotum 

 at the base, a transverse mark near the apex of the middle lobe, scutel- 

 lum, except for a mark on the base, post-scutellum, scutellar keels, a 

 large mark on the apical slope of the metanotum, its apex obliquely 

 dilated laterally, the sides of the dilated part oblique, straight ; the top 

 rounded ; a large mark on the lower part of mesopleurae, its basal half 

 narrowed and turned upwards, a narrow line on the apex reaching to 

 near the bottom from the top, a broad line on the upper three-fourths 

 of the apex of the metapleurae, bands on the apices of the abdominal 

 segments, broad on the basal segments, becoming narrower on the 

 apical, especially in the centre ; that on the penultimate wider and 

 more irregular, and the basal and apical ventral segments broadly, 

 pale yellow. Four front legs yellow, the femora fulvous, the apical 

 joints of the tarsi black ; the hind coxae black, a large yellow mark on the 

 top above, obliquely widened on the inner side, the basal joint of the 

 trochanters yellow, streaked with black above, the apical black ; the 

 femora fulvous, the base very slightly, the apical sixth black ; the tibiae 

 and tarsi yellow, the base of the former narrowly, its apex more 

 broadly black, as is also the extreme apex of the last joint of the hind 

 tarsi. The sixth to the eleventh joints of the antennae are white, 

 except above. Wings hyaline, the nervures and stigma black. 2 . 

 Length, 15 mm. ; terebra, 5 mm. 



Face and clypeus distinctly punctured, the latter more closely and 

 strongly than the former ; its apex transverse, tuberculate in the 

 middle, the sides distinctly curled up ; the tubercle on the face large, 

 longer than wide, narrowed below. Front and vertex smooth, the 

 latter slightly punctured in the middle, the former much more dis- 

 tinctly and closely punctured in the middle, where there is an indis- 

 tinct crenulated furrow. Mesonotum closely but not strongly punc- 

 tured ; the scutellum much more coarsely punctured, the post-scutellum 

 smooth. Base of metanotum smooth, the part between the base and 

 keel closely but not strongly punctured ; the apical part closely reticu- 

 lated ; the basal keel complete ; the apex with a broader keel on the 

 sides. Propleurse smooth, the middle and lower apical part closely 

 striated ; the mesopleurae, except at the apex above, closely finely 

 punctured ; the depression at the base with some stout keels, as has 

 also the bordering apical furrow. The metapleurae at the spiracles 

 finely punctured ; the lower basal part coarsely punctured, the apical 

 stoutly, obliquely striated, the striae more or less intermixing. First 

 abdominal segment smooth at the base, the dilated part closely but 

 not strongly punctured ; in its centre is a large ovate fovea ; the second 

 is closely, distinctly punctured, the third weakly punctured, the others 

 smooth.
