1910.] F0SS0RTAL WASPS OF AUSTRALIA. 339 



Pedinaspis nudiventris, sp. n. 



2 ■ Nearly velatecl to P. exulans, but differs as follows : — the 

 eyes are rather nearer together at the base than on the vertex, 

 so that the clypeus is not so broad ; the second joint of the 

 flagellum is slightly shorter than the third and less than twice as 

 long as the first ; the third transverse cubital nervure is much less 

 oblique ; the whole insect is less opaque and almost without grey 

 pubescence ; the spines of the tarsi are pale testaceous ; the wings 

 fiavo-hyaline on the basal half, subhyaline at the apex, nervures 

 fulvous at the base, fuscous at the apex. 



Length 9 mm. 



Hab. Mackay, Q. {Turner). October. 



The male has the eyes more nearly parallel, the joints of the 

 flagellum arcuate beneath, pronotum and median segment shorter, 

 and abdomen subcorneal. Antennae fusco -ferruginous ; fore tibiae 

 and tarsi testaceous brown.

5 . Clypeus more than twice as broad as long, broadly sub- 

 truncate at the apex ; the labrum exposed and narrowly truncate 

 at the apex. Eyes broadly and rather deeply emarginate ; 

 posterior ocelli twice as far from the eyes as from each other. 

 Antennae stout, slightly tapering at the apex ; a very delicate 

 longitudinal sulcus on the front not reaching the anterior ocellus. 

 Pronotum short, the posterior margin feebly arched, the anterior 

 angles rounded ; mesonotum with two rather obscure longitudinal 

 furrows ; scutellum convex. Median segment oblique, rather 

 broader than long, with a short furrow from the base not 

 reaching the middle. Abdomen ovate, short, not compressed 

 laterally. Median segment opaque, the remainder of the insect 

 smooth and slightly shining. Legs long and slender, the posterior 

 tibiao with minute spines. 



Black ; labrum, clypeus (except a median black line), inner 

 margins of the eyes broadly as high as the emargination, outer 

 margins of the eyes very narrowly, scape beneath, posterior 

 margin of the pronotum, propleurae anteriorly, tegulse, post- 

 scutellum, apical angles of the median segment, coxae, a line on 

 the anterior and intermediate femora beneath and on the anterior 

 tibiae and tarsi, and a narrow, short, curved band on each side on 

 the apical margin of the four basal abdominal segments yellowish 

 white ; anterior tibiae fusco-ferruginous ; posterior femora 

 ferruginous. Wings hyaline, with a faint and narrow fuscous 

 marginal band at the apex, nervures black. Second abscissa of 

 the radius longer than the third. 



Length 6-7 mm. 



$ . As in female, but the head is entirely black, the clypeus and 

 labrum fuscous, the scape alone marked with white beneath ; the 

 apical dorsal segment of the abdomen is white.
