Vertex of head only slightly shining; third joint of antennae 

 very long and slender, more than twice as long as the second, 

 the apical joint 'black or almost so. Pronotum not very shining, 

 and like other parts of the thorax more or less suffused or mark- 

 ed with black; mesonotum in the middle paler than the rest of 

 the thorax; propodeum very strongly raised or convex, the sur- 

 face dull, but with hardly visible sculpture on the middle behind 

 the spiracle, posteriorly transversely strigose. Abdomen 

 smooth impunctate, apparently glabrous. Length 3-3.5 mm. 



Hab. Columbus, Ohio, U. S. A. (Koebele). 



Pscndogonatopiis opaciis, sp. nov. 



Black or pitchy, the face below the antennae, the two basal 

 joints of these more or less, the anterior tibiae and tarsi, testa- 

 ceous. The posterior tarsi and part of the apical joint of the 

 antennae more or less, pale-coloured. 



Dull, the head densely and minutely sculptured, appearing 

 punctured, as also the whole of the thorax, even the posterior 

 face of the propodeum with this sculpture instead of the usual 

 transverse rugosity, and without evident pilosity. Abdomen 

 smooth and shining and bearing short pale hairs. Length 2-3 

 mm. 



Van a. (?immature) Paler, more pitchy than black with the 

 hind and middle tarsi quite pale and the apical joint of the anten- 

 nae much more distinctly so than in the type. 



Hab. Bundaberg and Brisbane, Queensland; bred. 



8. Psendogonatopus sfowcnini, sp. nov. 



Vertex of head dark, face and occiput pale, varying from fer- 

 ruginous to yellowish white. Antennae with the two basal, 

 sometimes the third, the apical, and one or two of the preceding 

 joints more obscurely, pale. Pronotum ferruginous or brown, 

 often more or less suffused or marked with black; propodeum 

 black; legs testaceous, the front femora and tibiae especially, 

 more or less dark brown. 



Head and pronotum with extremely fine hardly visible punc- 

 tures, or surface sculpture; the propodeum with extremely dense 

 microscopic sculpture, appearing like fine and dense punctura- 

 tion, but due really to reticulation of the surface as in the pre- 

 ceding species. In profile the propodeum is not at all abruptly
