NOTES ON THE HYMENOPTERA CHALCIDOIDEA, 



WITH DESCRIPTIONS OF SEVERAL NEW 



GENERA AND SPECIES. 



By a. a. Girault, 



Brisbane. Australia. 



Family PTEROMALID^. 



Subfamily Sphegigastrin^e. 



Tribe Sphcgigastrini. 



URIOS, new genus. 



Female. — Eyes dark red. margined with ocher. ovate, moderate in size; 

 whole head reticulated, an ochreous area caudad of and bordering each eye ; 

 sparse, rather long white hairs on head ; antennae inserted about in the middle 

 of the face, distinctly above an imaginary line drawn between the ventral ends 

 of the eyes; occipital margin of vertex obtuse; lateral ocelli very far from the 

 eye margins ; antennal bulbs separated for half their own width, distant from 

 the eyes ; antennal scobe barely indicated just above the insertion, the face 

 shallowly concave above bulbs ; beneath them crossed by a broad, somewhat 

 irregular ochraceous band which also extends somewhat above them. Cephalic 

 ocellus nearly in cephalic aspect, the scape reaching above it. Head subtri- 

 angular, not much wider than the thorax. Clypeus not conspicuous. Maxil- 

 lary palpi 4-jointed, the apical joint long, equal to the two preceding joints ; 

 labial palpi 3-jointed. 



Both mandibles tri-dentate, the third tooth shortest, broadly truncate (but 

 its apical margin slightly emarginate, giving the appearance of two weak 

 teeth on each side), the two outer teeth subobtuse. distinct but not strong, the 

 outer the longest (of itself short). 



•Antennae 12-jointed, subclavate or cylindrical and enlarging gradually to 

 end of club-scape; pedicel, one large ring-joint, 5 funicle joints, and a 4-jointed 

 club : ring-joint long but still wider, distinct ; scape obclavate, with its bulb 

 about thrice the length of the usual obconic pedicel, the latter subequal in 

 length to the rather long first funicle joint ; remaining funicle joints shorten- 

 ing distad and slightly widening, the distal one somewhat wider than long, 

 somewhat less than half the length of the first : club conic-ovate, not as long 

 as the scape, the joints subtjuadrate excepting the last, which is very small, 

 resembling a large tubercle or Ijutton. Pubescence of antenna consists of 

 stiff, rather sparse, rather long bristles. Funicle joints narrowed somewhat 

 proximad, their disto-lateral angles acute. 



Legs normal, the tarsi s-jointed, the proximal joint long, the tibial spurs 

 single, not more than a fourth the length of the first tarsal joint yet moder-
