206 THE ENTOMOLOGIST. 



.Cyprus. — One Acidalia (October, 1890), which I have not yet suc- 

 ceeded in determining. 



Marmarice, Coast of Syria. — Zonosoma pupillaria, Hb., two, one 

 closely approximating to ab. nolaria, Hb. 



There are in all about thirty-nine species represented, about 

 one-half of them being good local southern species ; one belongs 

 to the Geometridse {sens, str.) ; about twenty to the Acidaliidse 

 (eighteen to Staudinger's great genus Acidalia) ; ten to the 

 Larentiidse ; and only eight to the large family Boarmiidse. 



NOTES ON THE BEE-GENUS HALICTUS. 

 By T. D. a. Cockerell. 



In the 'Canadian Entomologist,' September, 1902, Mr. Charles 

 Eobertson gives a synopsis of the Halictinse found in the vicinity 

 of Carlinville, Illinois. In this work the old genus HalicUis is 

 divided into Halictus, Latr., Lasioglossum, Curtis, Evylmis, Eob., 

 Dialictus, Rob., Chloralictus, Bob., and Paralictus, Rob. One's 

 natural wish is to accept these genera, as Halictus, in the broad 

 sense, contains so many species ; but, if they are valid, they 

 should remain distinguishable when all the known forms are 

 considered. In order to test the validity of some of the charac- 

 ters used by Eobertson, I have examined a number of American 

 and European species, the latter received through the kindness 

 of Mr. H. Friese. 



A character given ior Lasioglossum hj Mr. Robertson is "hind 

 spur [of hind tibia] finely serrate " in the females. Unfortunately 

 H. xanthopus, Kirby, the type of Lasioglossum, has this spur 

 pectinate with four large blunt teeth, and several little ones. 

 However, Lasioglossum is ordinarily easily distinguished from 

 Halictus proper (as represented by H. scabiosce in Europe, or 

 H. lerouxii in America) by the short third submarginal cell, the 

 outer margin of which is gently curved. In typical Halictus this 

 cell is considerably produced, the outer margin showing a distinct 

 double curve. Using this character of the venation, the following 

 clearly belong to Halictus proper : — 



American. European. 



lerouxii, ligatus, scabiosce, cariniventris, 



parallelus, and fasciatus, virescens, maculatus, 



cited by Robertson. patellatus, tetrazonius. 



H. patellatus, Mar. (a large black species with banded abdo- 

 men) has the hind spur of hind tibia of female with few large 

 teeth. li. virescens, Lep., collected by Friese at Bozen, Tirol, 

 April 30th, 1898, is a beautiful insect, bright olive-green, with 

 continuous ochreous hair-bands on abdomen ; it has the third
