IS 



rax behind the constriction with evident pale hairs beneath and 

 at the sides, but above ahnost glabrous, posteriorly finely trans- 

 versely rugose, on the disc highly polished. Femora with short, 

 inconspicuous, pale hairs. Basal joint of front tarsi about equal- 

 to the fourth joint, thin basal portion of front trochanters short, 

 chelae normal for Jassid parasites. Abdomen very smooth and 

 shining, with a few short and inconspicuous hairs. Length 3 mm. 

 Hab. Java, Pekalongan (Muir). 



Dicondylus plcbcius sp. nov. 



Brown or ferruginous, the head above generally darker brown, 

 the abdomen black, but with a ferruginous spot behind the pedi- 

 cel ; mandibles (more or less) and front of scape yellow, second 

 and usually more or less of the third joint of antennae testa- 

 ceous, the following joints black. Pronotum and other parts of 

 the thorax sometimes with darker markings. Front femora and 

 sometimes the tibiae more or less darkened, the apices of the 

 former pallid. Mesonotal constriction evidently paler than the 

 adjoining parts of the thorax. 



Head above concave, usually not highly polished, though more 

 or less shining, clothed with erect hairs posteriorly. Third joint 

 of antennae about one and a half times as long as the fourth, 

 the latter considerably stouter. Pronotum and disc of the pro- 

 podeum highly polished, the mesonotal constriction dull, the tho- 

 rax bearing scanty erect hairs ; the propodeum posteriorly very 

 finely transversely rugulose. 



First and fourth joints of anterior tarsi subequal, chelae of the 

 usual type in Jassid parasites. All the femora with distinct 

 clothing of sparse erect hairs. Abdomen shining, sparsely clothed 

 with distinct erect hairs. Length 3 mm. 



Closely allied to Gonatopus austral iae, but distinguished by the 

 ferruginous propodeum with shorter hairs, and the distinct ab- 

 dominal pubescence, which is not confined to the base. 



Hab. Java, Pekalongan (Muir) ; bred from nymph of Jassid; 

 larval sac dull black, placed ventrally on the abdomen of the leaf- 

 hopper. 



Dicondylus jaz'aiius sp. nov. 



Black, the face below the antennae, and the scape in front yel- 

 low, the following antennal joints testaceous, the three or four 

 apical ones dark fuscous or black ; trochanters, tibiae and tarsi
