HYMENOPTERA PARASITICA 301 



Aglaotoma Forster. 



1869. Aglaotoma Forster, Verh. zool.-bot. Gesell. Wien, xix. pp. 344 & 354. 



Two distinct species, belonging to this genus, have been recognized, differing 

 greatly in size and requiring no table for their separation. 



(i) Aglaotoma rufiventris, sp. nov. 



%. Length 25 mm. Polished black, the abdomen, except along the dorsum and 

 at apex, dark rufous : legs reddish-yellow. The antennae are 1 3-jointed, filiform, a 

 little longer than the body, pilose ; the scape is obconical, about as long as the first joint 

 of the flagellum but stouter ; the pedicel is subglobose, a little longer than thick ; the 

 first joint of the flagellum is the shortest joint, being only about two-thirds the length of 

 the second joint ; the following joints are all a little longer than the second, subequal, 

 except the last, which is slightly longer than the penultimate joint. The scutellum at 

 the sides is rugulose, the cup being rather large oval with a large fovea at apex and two 

 or three minute punctures along the lateral margins. The metathorax is finely wrinkled 

 and bicarinate. The abdomen is hardly .so long as the head and thorax united, bldnt at 

 apex, with tufts of pubescence on each side at base. 



Hab. Hawaii: Kilauea, in July. One % specimen. 



(2) Aglaotoma molokaiensis, sp. nov. 



%. Length i -3 mm. Polished black ; antennae brown, the two basal joints 

 yellowish ; legs brownish piceous, the trochanters, apices of the femora, anterior tibiae 

 and tarsi and basis of the hind tibiae and tarsi, honey-yellow ; wings hyaline, the veins 

 pale yellowish, the marginal cell closed. 



The antennae are 1 3-jointed, gradually thickened toward apex, the first two joints 

 of the flagellum subequal, the first slightly the shorter, the joints beyond delicately 

 fluted, stouter, ellipsoidal and a little longer than thick. The scutellum is indistinctly 

 aciculated at the sides, the cup being oblong-oval, with a small fovea at apex, and two 

 microscopic, scarcely perceptible punctures on each side before the fovea. Metathorax 

 subopaque, sparsely pubescent and bicarinate. The abdomen, seen from above, is 

 obovate, slightly compressed and not or scarcely longer than the thorax. 



Described from i $ specimen.
