Note on Sphex flava, Fabricius, and its allies. 



"Working out the fossorial wasps belonging to the family 

 Pompilidce in my collection, I have been greatly puzzled to make out 

 what the SpJiex flava of Fabricius is. The insect I identify as such 

 is floured on pi. II, fig. 1^ It has the head, the thorax above as far as 

 the postscutellum, the wings except at the apex, the legs in part, and 

 the three apical segments of the abdomen ferruginous, the pectus, 

 sides, metathorax, the coxse trochanters and base of the femora, and 

 the basal segments of the abdomen jet-black ; the apex of the forewing 

 beyond the radical cell is fuscous-brown with a purple effulgence. 



Fabricius in the " Entomologia Systematica," vol. iij p. 217, thus 

 describes SpJiex flava i — 



" 80. S. Atra, dorso anoque ferrugineo, alis apice fuscis. 



* Smith. (Jour. Linn. Soc, vol. ii, p. 97) has described a species, Macromeris argeniifrons, 

 Ivora. Borneo, Malacca, Singapore and Java as having " the tibise slightly spinose," a 

 character not in accordance with Lepelletier St. Fargeau's original diagnosis of the genus. 

 I think it probable Smith's species, when the types are carefully examined, will prove 

 to be not a Macromeris at all.
