176 [August, 



types of Forster's monograph of this genus in his hands, and he has 

 made the above identification. The ? only was described by Forster, 

 but it seems clear that it is identical with our British species. 



Prosopis hrieclilaumeri, Forst. (Ent. Mo. Mag., xxxvi, p. 49) 

 = palusfris, Perk. 



This distinct species, introduced by Mr. K. C. L. Perkins, was 

 taken by bim in Wicken Fen and in similar localities in Suffolk, 

 frequentintr flowers of brambles, thistles, &c. and burrowing in the 

 dry stems of reeds. 



Its nearest ally is P. communix, but TcriecTihaumeri is larger and stouter. The 

 face in the g is entirely yellow below the antennae, the colour continued backwards 

 broadly along the borders of the eyes for some distance above the insertion of the 

 antennse, and of a paler tint than that of communis. The 7th and 8th rentral 

 segments are unlike those of any of our species, and are well figured in 

 Mr. Perkins' paper {loc. cit.). The ? may be known by the impunctate basal 

 segment of the abdomen and the structure of the propodeura, which in Tcriech- 

 haumeri is less abrupt posteriorly, and the central area is reduced posteriorly to 

 a narrow median line. 



Halictus freygessneri, Alfk. = suhfasciatus, Smith, E. Saund. (partim) 

 (Ent. Mo. Mag., xl, p. 250). 



(? flagellum of antennse paler beneath (very pale testaceous after the Ist joint), 

 the contrast between the 1st and 2nd very strong, face decidedly narrower than in 

 fulvicornis, only slight indications of the basal spots on the 2nd and 3rd abdominal 

 segments, posterior tarsi wide, 2nd joint as wide as long, genital armature dark 

 brown. 



? face narrower, propodeal area smoother, i.e., with the rugosities less defined, 

 abdominal segments impunctate or nearly so at the base, basal pubescent spots of 

 the 2nd scarcely indicated, apical margins of the segments only very narrowly dark 

 testaceous. 



Scotland, Ilfracombe, Tunbridge Wells. 



Ralictus fulvicornis, Kirh. = suhfasciatus, Smith, E. Saund. (partim) 

 (Ent. Mo. Mag., xl, p. 250). 



J antennae darker beneath (dark testaceous), face distinctly wider, conspicuous 

 spots of white pubescence at the base of the 2nd and 3rd abdominal segments, 

 posterior tarsi narrower, the 2nd joint decidedly longer than wide, genital armature 

 testaceous red. 



? face shorter, propodeum with the rugosities more pronounced and more 

 clearly defined (crisper), abdominal segments finely but distinctly punctured at the 

 base, lateral pubescent spots of the 2nd and 3rd well defined, posterior margins 

 widely testaceous. 



A fairly common species in the South, but it is difficult to get at
