NEW BRACONIDiE FROM BORNEO. 295 



phoehe, Eiivanessa antiopa, Leucophasia sinapis, Pyrameis atalanta, 

 Limenitis cainilla, Euchloe cardamines, and Epinephele ianira. 

 Larvae of Euvanessa antiopa and Eugonia polychloros were ex- 

 ceedingly abundant on the sallows, and I brought away a batch 

 of ova of the former species, from which a fine series of imagos 

 was reared in August ; a large number of these I turned out in 

 the garden here.

DESCRIPTION OF A NEW GENUS AND SPECIES OF 

 BRACONID^ FROM BORNEO. 



By p. Cameron. 



Pachybracon, gen. nov. 



Eyes large, pubescent ; there is a distinct malar space ; temples 

 wide, obliquely narrowed ; the occiput transverse, not margined. 

 Palpi long, stout, the maxillary six-jointed. Four front legs normal, 

 the hinder long, thickened, densely haired, especially the tibise, on 

 which the hair is long, dense, thick, as it is also on the metatarsus. 

 Calcaria moderately long ; the claws small, simple. Otherwise as in 

 Bracon. The antenna are placed on the top of the head ; the meso- 

 notum is trilobate ; the abdomen is broader than the thorax and is 

 ovate ; the basal segment is broad at the base ; the apex is as broad 

 as the length ; there is no keel on the second segment ; there is a long 

 ovipositor ; the basal joint of the hinder tarsi is shorter than the 

 others united ; the third and fourth are smaller than the second or 

 fifth. The antennae are longer than the body, are stout, and of equal 

 width. There is a distinct, crenulated, suturiform articulation. 



This genus may be described as a Bracon with hairy eyes, 

 and with the hind legs greatly thickened and densely covered with 

 long stiff hair. No species of Braconinae with pubescent eyes 

 has hitherto been described, although hairy eyes are known with 

 some of the other groups, e. g. with Chelonus. 



Pachybracon fortipes, sp. nov. 

 Black ; the basal two-thirds of the antennal flagellum rufo- 

 testaceous ; the wings blackish to the base of the stigma (including 

 the first cubital cellule), milky hyahne beyond ; the hind wings 

 blackish to near the apex ; the stigma, except in front, the radius, 

 and the cubitus from the first transverse cubital nervure are pale 

 yellow, almost white ; the recurrent nervure is almost interstitial. 

 Head and thorax smooth and shining, sparsely covered with short 

 black hair, the pubescence on the face paler, on the palpi white. 

 Abdomen opaque, closely, rugosely punctured, the apical two seg- 

 ments smooth and shining. The apical abscissa of the radius is as 

 long as the basal two united. Length, 7 mm. ; terebra, 2 mm. ? .
