pilosity. Abdomen smooth, shining, glabrous. Length 2-2.5 mm. 

 Hab. Bundaberg and Childers, Queensland; bred. 



2. Haplogonatopits iiiocstiis, sp. nov. 



Apparently identical structurally with the preceding, but the 

 apical joint of the antennae is not pale, nor does the mesonotum 

 differ greatly from the rest of the thorax in colour, and conse- 

 quently the two forms are very easily distinguished by colour 

 characters, which appear to be of specific importance. 



Hab. The Mulgrave near Cairns, Queensland; bred. 



3. Haplogonatopiis anicricanus, sp. nov. 



Ferruginous to testaceous in colour ,the abdomen black, or 

 obscurely pallid, changing much during life in some individuals. 

 The antennae black, the apical joint and the two or three basal 

 ones pale. Head generally brown on the vertex, parts of the 

 thorax also sometimes more or less darkened. 



Head with scarcely visible sculpture; pronotum shining, the 

 transverse impression just perceptible at least at the sides in 

 some examples, very minutely, in fact hardly perceptibly, punc- 

 tured; propodeum dull, with microscopic surface rugulosity, 

 and not at all pilose. Abdomen smooth, glabrous. Length 

 about 2.5 mm. 



Hab. Columbus, Ohio, U. S. A. (Koebele and Swezey). Mr. 

 Swezey was of the opinion that this species w^as Gonatopus 

 Incolor Ashmead, but that species has the "metathorax smooth, 

 polished." I have bred about 150 females of H. amcricmuis with- 

 out apparent variation. 



PARAGONATOPUS, gen. nov. 



Head evidently, but only lightly, concave on the vertex; third 

 joint of antennae very long (about twice as long as the fourth 

 in the typical species). Mandibles 4-dentate, maxillary palpi only 

 two-jointed, one elongate joint beyond the geniculation and ap- 

 parently only one before this, the extremely short basal joint, 

 that is present in allied genera, being apparently absent. Tro- 

 chanters of front legs, as well as the tarsi and claw of chelae and 

 the form of the pronotum, etc., as in the preceding genus.
