carina; the fine sculpture of the propodeum is extremely dense. 

 I'he abdomen is extremely densely and minutely punctured. 

 Length about 3 mm. 



Hab. Bundaberg, Queensland; bred. 



4. Chalcogonatopus (Eugonatopus) pscudochromus, sp. nov. 



Ferruginous or more or less testaceous, the propodeum, and 

 head above, black or dark; basal two joints of antennae quite 

 pale, the following less clearly so, the rest black or fuscous. 



Antennae less slender than in any of the preceding, scape as 

 long as the fourth joint, seventh, eighth and ninth not twice as 

 long as wide. Head dull, appearing densely and minutely punc- 

 tate, the pronotum with very similar sculpture; the propodeum in 

 front and posteriorly finely transversely rugose, in the middle 

 sculptured like the head, not pilose nor pubescent; at the sides 

 without any suture or impression dividing off the mesopleural 

 region. Abdomen smooth, without pubescence or pilosity, the 

 base black, and elsewhere more or less stained with fuscous. 

 Legs neither pilose nor pubescent. Length about 4 mm. 



Hab. Columbus, Ohio. (Koebele). 



ECHTHRODELPHAX P. 

 (Bull. L, Div. Ent., Board Agr. & For.. Territory of Hawaii). 



Head above concave or impressed, and the face in front view 

 sirongly transverse, of triangular shape, and very similar to that 

 of Neodryinus. Ocelli in a triangle of very elongate isosceles 

 form, the front one very distant from the two basal ones, which 

 are near together. Maxillary palpi short, four-jointed, labia! 

 palpi two-jointed. Mandibles quadridentate. The mouth parts 

 in fact are practically as in Pseiido-gonafopus' as also is the 

 pronotum, which has a distinct transverse impression. Mesono- 

 tum wider than the pronotum, shaped like that of Neodryinus, 

 and with no resemblance to that of Gonatopus' etc., the parap- 

 sidal furrows quite distinct, enclosing a very narrow, median, 

 elongate, triangular area. Wings fully developed, and with the 

 usual neuration of the group. Front legs and chelae practically 

 ^.3 in Psendogonatopus. 



Male with the short palpi of Psendogonatopus, etc.- but the 

 extremelv long, thin, filiform antennae and the subincrassate 

 head will easily distinguish it generically, as also from any of 

 the other allied genera with apterous females.
