NEW AND LITTLE KNOWN INDIAN HYMENOPTERa. 513 



without pubescenco or pile, showing the striation clearly. Although the 

 anterior femora are emarginate in the ^ , it is a Tachytes, and not a Tachy- 

 sphex. It is very distinct from any other Indian species of the genus. 



Tachytes opulenta, n. sp. 



$. Clypeus and front with the sculpturing hidden by the pubescence, ex- 

 cept at the apex of the clypeus, which is rugosely punctured ; vertex, mesono- 

 tum, scutelluni, postscutellum, and median segment very finely and closely 

 punctured ; abdomen minutely aciculato, 1st ventral segment minutely and 

 closely punctured, remainder shining, with scattered punctures, closely punc- 

 tured at apex. Front with a distinct furrow not reaching the vertex, and with 

 the usual smooth curved carina from each of the posterior ocelli towards the 

 anterior ocellus ; distance of eyes apart at vertex equal to the 2nd joint of 

 flagellum ; mesonotum with three longitudinal carina; at base, not reaching the 

 middle ; median segment short, roundly truncate at apex, with a median lon- 

 gitudinal furrow ending in a fovea where the truncation begins ; there is no trace 

 of a furrow on the scutellum. Black ; clypeus and front, apices of 1 — 4 

 abdominal segments, apex of femora, the whole of the tibi«, and the metatarsi 

 covered with thick golden pile ; thorax with sparse greyish pubescence ; sides of 

 abdomen and penultimate segment at apex with stifE black and testaceous hairs ; 

 pygidium with black and golden pubescence intermixed ; wings flavo-hyaline, 

 nervures and tegulse testaceous. 



^. Similar, eyes separated only by half the length of the 2nd joint of fla- 

 gellum, pubescence on pygidium silvery. 



Tachytes asttda, n, sp. 



^. Head and thorax very closely and finely punctured, granular, abdomen 

 minutely aciculate, ventral segments shallowly but somewhat closely punctur- 

 ed. Anterior margin of clypeus rounded, strongly depressed, with two blunt 

 teeth on each side ; an impressed line from vertex to base of antenna ; the 

 ocelli of the form usual in the genus ; the distance apart of the eyes at vertex 

 is less than the length of the 2nd joint of tlagellum ; scutellum with an indis- 

 tinct median impression ; median segment roundly truncate posteriorly, with 

 a deep longitudinal impressed line along the posterior half of the segment : 

 pygidium broadly rounded at apex. Black ; the palpi and mouth parts, cal- 

 caria, tibial and tarsal spines, and claws at base red ; scape of antennae, clypeus 

 and front with pale golden pubescence ; thorax, median segment, and basal 

 abdominal segment with long pale pubescence, which has a golden tint in fresh 

 specimens ; Ist abdominal segment at apex narrowly, and 2nd, 3rd and 4th 

 broadly covered with silvery pile ; the pubescence on pygidium silvery ; legs 

 with short golden pile. Wings flavo-hyaline, nervures and tegula; rufo-testa- 

 ceous ; the Ist recurrent nervure is received into the 2nd cubital cell near its 

 basal angle, so that the space on the cubitus bounded by the 1st cubital and 1st 

 recurrent nervures is less than half the space bounded by the two recurrent 

 nervures.
