6. Neochelogynus destructor, sp. nov. 



Black, the mandibles except the teeth, the two basal joints of 

 tlie antennae and sometimes the third more or less, all the legs, 

 excepting usually the front femora, ferruginous. 



Female. Head with reticulate, rugose sculpture, due probably 

 to the confluence of coarse and very shallow punctures. An- 

 tennae with the second joint fully as long as the third, fifth at 

 its widest, much wider than the fourth, and like the sixth not 

 much longer than its greatest width. Pronotum somewhat longi- 

 tudinally rugose; the mesonotum very finely and indefinitely, 

 sparsely punctate; propodeum with the dorsal surface short, 

 rugose, well marked off posteriorly by a distinct raised line ; pos- 

 teriorly its surface dull, rugulose or granulate, the median area 

 very distinctly marked by clear raised lines. Wings clear, neura- 

 tion and stigma pale, yellow. Length 2.5-3.5 mm. 



Male. Black, legs, mandibles and one or more of the basal 

 joints of the antennae, ferruginous; usually several joints of the 

 flagellum are more or less pale, becoming from the first more 01 

 less darkened to the apical joints, which are quite black. 



Head in front with the sculpture as in the female, but much 

 feebler and more obsolete; antennae with short, moniliform 

 joints of subsequal length, except the scape, which equals the two 

 following together. Pronotum very short, entirely concealed, if 

 the head be laid back; mesonotum smooth, hardly perceptibly 

 punctured, or impunctate; propodeum finely rugose, the posterior 

 median area, which is quite definite, coriaceous, dull. Postmar- 

 ginal nervure dark and the stigma with dark margin. 



Hab. Bundaberg, Queensland; bred. 



7. Neochelogynus cognatus, sp. nov. 



Differs from the preceding as follows: 



The basal two joints of the antennae are clear ferruginous, the 

 following two or three more or less sordidly so and the rest fus- 

 cous. All the legs entirely pale. The pronotum is to a large 

 extent smooth and shining, the mesonotum very smooth with a 

 few scattered punctures; the propodeum posteriorly within the 

 median- area is much smoother, and hardly opaque. Length 

 about 3 mm. 



Hab. Bundaberg. Queensland; bred.
