P. CAMERON. HYMENOPTERA I. 



Eyes above converging; separated at the top by the length of the y^ antennal joint, 

 which, with the pedicle, is nearly as long as the following 2 joints united. Apex of clypeus 

 almost transverse, with the sides rounded. The vertex, occiput, prothorax and pleurae thickly 

 covered with longish black haïr. Apex of pro- and base of mesonotum rounded, not angled 

 in the middle. There is a deep longitudinal furrow on the apical half of the mesonotum; the 

 centre of the scutellum broadly depressed ; the post-scutellum with a shallow furrow in the 

 centre. Outer calaria black, the inner for the greater part rufous. The basai half of the raan- 

 dibles and the palpi ferruginous, the apical half of the former black. Mandibles broadly rounded 

 at the apex, without teeth; the middle with a distinct, deep, curved furrow. 



The cf 1 is smaller (15 mm.) and similarly coloured except that the wings hâve a narrow 

 fuscous border; the y A and 4 th joints of the antennae are equal in length, the legs are less 

 strongly spinose and serrate and the mandibles hâve an indistinct subapical tooth. 



Pompilus Fab. 



1. Pompilus manokwariensis sp. nov. 



Manokwari, 15 May. 



Black, spotted with silvery patches, wings fuscous, iridescent, the stigma and nervures 

 black; the 3 ld cubital cellule almost appendiculate, the nervures rounded, touching in front. Q. 



Length 8 mm. 



The silvery pubescence appears to be arranged in regular patches — on the clypeus, 

 lower inner orbits, the outer entirely, base of mandibles, the sides of the pronotum at the 

 base and apex, on apex of mesonotum, post-scutellum, base of propleurae, the lower half of 

 the apex of mesopleurae, the apical half of the metapleurae and spots, obliquely narrowed 

 on the innerside, on the sides of the abdominal segments. Apex of clypeus transverse, the 

 sides rounded. The 2nd récurrent nervure is received very shortly behind the middle of the 

 cellule; the transverse médian nervure received shortly beyond the transverse basai, the 

 cubitus in hind wings received very shortly behind the transverse médian, almost interstitial. 

 Eyes slightly converging above ; the hind ocelli separated from each other by a slightly less 

 distance than they are from the eyes. Médian segment posteriorly rounded, without an im- 

 pressed line above. Fore tarsi with stiff long spines; the claws with a médian tooth. Marginal 

 cellule acutely pointed at apex. Pronotum as long as mesonotum, roundly arcuate. First joint 

 of flagellum clearly longer than the second. 



Mygnimia Sm. 



1. Mygnimia aspasia Sm. 



A spécimen of what I take to be this species (described : Proc. Linn. Soc. 1859, p. 157 

 from Aru, and recorded /. c. 1860, p. 121, from Amboina and Doré, New Guinea), is in the 

 Collection from Wa Udu, August. The claws are stout, almost bifid, the inner claw being 

 stouter than the outer, and reaching shortly beyond its middle; the eyes converge very little 

 above and are separated there by about the length of the 3 ld antennal joint. The hind ocelli 

 are separated from the eyes by about double the distance they are from each other. Apex
