type of HalidoideSj the condition of the blade is essentially 

 as in H. tinsleyi. In H. paradoxus, Moraw., the outer 

 portion is also well developed, ending obtusely 187 /x before 

 the rather narrow apex of the blade, which bears very long 

 bristles. In Dufourea vulgaris the blade is narrow, with 

 long bristles. The bipartite condition of the maxillary blade 

 is very strongly developed in Halictus, e. g. H. sisymbrii, 

 Ckll., and H. armaticeps, Oresson, and the European H. vi- 

 rescens. In Melitta leporina there is no sign of it. In 

 Pseudopanurgus cetkiops, Cress., the outer or subhyaline area 

 is present and tapers apically as in Amblyapis. In Nomii. 

 nortoniy Cress., the outer area is present, but narrow (about 

 one-ninth total width of blade) and tapering. In Dasypodi 

 plumipes it is reduced to an inconspicuous subhyaline margin, 

 broadening basally, where its width is about one-fifteeuth that 

 of the blade. 



Agapostemon texanus iowensis, subsp. n. 



? . — Similar to A. texanus, Cresson, but rather small 

 (anterior wing 7^ mm.) ; mesothorax, while showing the 

 double puncturation of texanus quite distinctly, much rougher, 

 the smaller punctures more crowded; metathorax with the 

 basal triangle distinctly defined by raised lines, but the sculp- 

 ture coarser than in subsp. subtilior, Ckll. ; abdomen broader 

 than in A. radiatus. 



Hob. Ames, Iowa, 1899 {Wilmon Neioell). 



Possibly a hybrid witli A. radiatus. The abdomen is 

 without evident hair-bands ; in subtdior these are very distinct. 



Antkidium subochraceum, Walker, 1871. 



This species, from Mount Sinai, was very poorly described 

 by Walker, and has never been recognized since. I examined 

 the type at the British Museum, and am able to add the 

 following particulars : — Front down to clypeus black, except 

 for a red band below middle ocellus and the broad (narrowing 

 at summit) yellowish-ferruginous bands next to orbits ; 

 mandibles 4-dentate ; hair of head and thorax above strongly 

 fulvous ; punctures of abdomen rather large. Wing3 reddish, 

 apical region suffusedly darker; stigma ferruginous. Legs 

 ferruginous shaded with orange ; apparently no pul villi. 

 Abdomen above dark reddish, with the bases of the second 

 and following segments broadly and suffusedly blackened, 

 the hind margins of the segments a sort of pale orange ; scopa 

 white ; second r. n. going beyond second s.m. ; scutellum
