NEW AND LITTLE KNOWN INDIAN HYMENOPTERA. r»ir. 



femora scarcely emarginate at base, but with a slight depressioa ; median 

 segment about the length of moaonotura, roundly truncate posteriorly, the upper 

 portion boimded at the sides and apex by a furrow ; apical margins of abdominal 

 segments depressed ; pygidium roundly incised. Black ; the mandibles reddish 

 before apex ; all the tarsi rufo- testaceous ; apical margins of abdominal sogmonis 

 under the pile testaceous. Pubescence on clypeus silvery, on front rather long and 

 dark fuscous ; on thorax silvery and rather thick at the sides; abdominal segments 

 1-3 with somewhat wide bands of silvery pile : wings hyaline, nervures. stigma, 

 and tegula) rufo- testaceous ; the 1st and 2nd cubital cells are subequal on the 

 radial nervure, the 3rd shorter ; the 1st recurrect nervure is received into the 

 2nd cubital cell before the middle, the 2nd after the middle. 

 riab. — Deesa ', November. 

 Length — 12 mm. 



This species is nearest to T. testaceijm (Bing.), but may be distinguished from 

 it by the finely rugose median segment. From T. selechis described above it 

 may be distinguished by the pubescence on front being dark fuscous. 

 Tachysphex heliophilus, n. sp. 



9. Clypeus sparsely, front and vertex closely and finely punctured : 

 mesonotum rugosely punctured, granular ; scutellum shining, sparsely punc- 

 tured ; median segment minutely reticulate, its apex transversely striate ; 

 abdomen smooth. Front with the usual furrow ; the distance ot the eyes 

 apart at vertex slightly greater than the length of 2nd joint of flagellum : 

 median segment about the length of mesonotum, roundly truncate posteriorly : 

 abdomen shorter than head and thorax united, pygidium with a few punctures. 

 Black ; the 1st and 2nd abdominal segments red ; pubescence and pile short, 

 sparse, silvery ; calcaria and tibial and tarsal spines black. Forewing flavo- 

 hyaline. with a light fuscous cloud across the radial. 2nd cubital, and dis- 

 coidal cells ; nervures and tegulae rufo-testaceous ; radial cell rather long, 

 rounded at apex ; the 2nd and 3rd abscissas of radial nervure subequal, 

 the 1st slightly longer ; the 1st recurrent nervure is received into the 2nd 

 ubital cell before the middle, the 2nd at the middle ; hindwing hyaline, 

 ^. Similar, smaller, the pubescence on the front golden ; the posterior 

 tibiai and all the tarsi more or less rufous ; anterior femora emarginate at base. 

 Hab. — Deesa ; February. 

 Length — 9 7^ mm. ^ 6 mm. 



The only Indian species with a red base to the abdomen and a fuscous cloud 

 across the forewing. 



Tachysphex inimitus, n. sp. 



9. Head, mesonotum, scutellum ; and postscutellum closely and finely punc- 

 tured ; median segment longitudinally striate at base, transversely apex ; abdo- 

 men aciculate, almost punctured. Clypeus transverse anteriorly, front with a 

 shallow impressed line ; the distance apart of the eyes at vertex is less than 

 the length of the 2nd and 3rd joints of the flagellum united : median segment 

 very short, about half the length of mesonotum, truncate posteriorly : abdomen
