NOMIA FROGGATTI, n.Sp. 



^ Length 11 mm. or slightly over; robust, black, the hind 

 margins of the first four abdominal segments with pale orange 

 tegumentary bands, flushed with emerald-green laterally (one 

 specimen has the bands bright terracotta red, but they have 

 probably been altered by cyanide) ; head and thorax above 

 with bristly black hair, at sides and beneath with pale yel- 

 lowish hair, but some black on upper part of pleura, middle 

 of tubercles, and face (especially at sides) down to about the 

 middle : abdomen with pale hair at base, otherwise with black, 

 the black hairs overlapping the bands ; venter with light red- 

 dish hair ; legs with hair partly light reddish, partly black ; 

 black on outer side of hind tibiae, reddish on inner side, con- 

 trasting ; middle femora at base beneath with a stiff brush of 

 orange-red hair (exactly the same in the Indian X. elliofii) : 

 clypeus rough, with a delicate median keel ; mesothorax dull 

 and very densely punctured ; scutellum slightly bigibbous : 

 postscutellum armed as in X . eUiotii, but very much less light 

 tomentum ; base of metathorax with evident cross-keels (in 

 X . eUintii they are nearly obsolete) ;abdomen rough, closely 

 punctured (in X . eUiotii very sparsely) ; tegulae piceous : wings 

 strongly dusky; first r.n. joining the small second s.m. beyond 

 middle. 



^r/^>.— Solomon Islands, July- August, 1909, 2 9 's(W. W 

 Froggatt, No. C 12). An Indo-Malayan type, of the group 

 of N. eUiotii Smith. It is really known from X . puJrhri- 

 halteata Cameron, by the different postscutellar armature, 

 that, in Cameron's species, consisting of more widely sepa- 

 rated, spine-like structures. In X . pulchrihalteata, the trun- 

 cation of the metathorax is shiny, with distinct punctures, 

 largely in rows ; in X . frofjgatti it is dullish, minutely 

 granular and finely tomentose, with small, scattered punc- 

 tures. Friese records X . eUiotii from Key Island, biit, as he 

 says the female is without a green band on the first abdominal 

 segment, it is evident that he has a distinct species.
