ity of the tegulae of the male ; the metathorax is rather similar 

 in the two species and the constriction of the abdomen so pro- 

 nounced in Cresson's species is present in the male and indi- 

 cated in the female of the present species. H. jamaicae differs 

 from the older species in the finer and more scattered punctures 

 of the mesonotum and in the dark brown, not honey colored, 

 stigma and nervures. 



In the present connection the relationship of H. coactus to 

 the species of the tegularis group might be discussed. This re- 

 lationship was suggested by the form and sculpture of the 

 tegulae of H. coactus and H. tegularis Robertson ; in both spe- 

 cies the tegulae are longer than the average for the genus and 

 distinctly pointed behind, the point turning mesially. In H. 

 tegularis the entire surface of the tegulae is coarsely and close- 

 ly punctured, while in H. coactus a large central space is bare 

 and shiny ; behind the punctures are like those of H. tegularis, 

 but in front they are a little finer. The second and sometimes 

 the third abdominal segment in H. tegularis, H. pseiidotegu- 

 laris Cockerell, and H. tegularifonnis Crawford, show the in- 

 flation on either side just above the apical margins as in H. 

 jamaicae, but to a less degree. The mesonotum in all five spe- 

 cies mentioned is sharply lineolate ; and the knees and tarsi in 

 all five are somewhat paler than the rest of the legs. In the 

 light of the relation of H. coactus to H. jamaicae the tegularis 

 group is brought nearer to the rest of the genus. 



Halictus deceptor sp. nov. 



9 Length 5 mm. Head and thorax blue-green, not brassy, abdomen 

 black. 



Face closely punctured, a little longer than broad, clypeus produced 

 two-thirds of its length beyond the eyes. 



Mesonotum shiny, with very fine punctures, well scattered in the 

 middle, but quite crowded on either side of the parapsidal groove. 

 Truncation of the metathorax rather broad, unsculptured and with 

 shiny rounded edges; the basal area with no indication of a rim, and 

 with but few, very short, weak and simple plicae reaching one-third of 

 the distance to the margin; its surface shiny, although somewhat 

 lineolate. Tegulae dark brown, shiny. 



Wings dusky brown, the stigma and nervures very dark brown. 



Legs blackish, shading into dark brown on the tarsi.
