mul distinctly cmarginatc in the middle apically, with a pair 

 of lateral wings on each side, the one wing overlying the 

 other — one pair siihoblong, with blunt, subtruncate, lateral 

 margin, rather inconspicuously ciliate ; the other much 

 narrower, dilated at the apex, with the basal lateral angle 

 acutely produced and the margin cons[)icuously ciliated 

 with long hairs. 



Other sexual characters are a curved strong carina on the 

 third ventral segment, defining a large flattened shining 

 plate, and a shining transverse ridge on the fourth. 



Another point ot" resemblance between this Ili/Iaoides and 

 some of the Australian Eumenidte is the deep black second 

 segment, the dull colour being due in both cases to a very 

 dense appressed black tomentum, quite similar in the bee 

 and wasps. 



EuRYGLossA, Smith. 



This large and dominant Australian genus has been much 

 studied by Prof. Coekerell, and he has formed new genera 

 or subgenera for allied forms. Generally speaking, the 

 Euryglossine section of the Prosopidae are easily distinguished 

 from Prosopis and its allies by the form of the tongue and 

 by the mandibles, which have a more acute appearance in 

 the females, owing to the apical tooth being well produced 

 beyond the inner one. In Euryglossa itself, in some species 

 the anteapical tooth is hardly, if at all, developed. A great 

 many at least of the species of the Euryglossine section have 

 the posterior tibiae spinose or subspinose. Euryglossa itself 

 in normal forms has much more of an Andrenoid facies than 

 most Prosojjida?, and the females, in such species as I have 

 been able to examine (as also those of the genera Pachy- 

 prosopis, Turnerella, Euryglossina, and probably others), have 

 a small but distinct bare pygidial area. The calcaria 

 of the hind tibiae are notably s})inose or serrate in such 

 Euryglossa, PacJiy prosopis, Stilpnosoma, and Turnerella as I 

 have been able to examine; but they are also notably so in 

 one group of species of Meroglossa and Palceorhiza in the 

 Prosopine section and in some Prosopis, e. g. P. elegans, &e. 



I have only examined the genitalia in one undetermined 

 species of Euryglossa. The genital armature is long, very 

 strongly rounded on the basal half, i. e. to the base of 

 the sagittse, which extend in dorsal view to the apices 

 of the stipites. The latter are long and slender on their 

 free portion, somewhat twisted, and with a roundish, 

 more membranous, dilated apex turned outwards, a little like 

 some species of Audrena. There are no long hairs or bristles^
