Nomia longitarsis Cockerell. 



Nomia longitarsis Cockerell, Entomologist 49 (1916) 158. 



The type is a male. The female (Mount Maquiling) is sim- 

 ilar, with the usual sexual differences, the mesothorax more 

 finely punctured, and the abdomen with much shallower and 

 more feeble punctures. The stigma in both sexes is ferruginous. 



Luzon, Laguna Province, Mount Maquiling {Baker). 



Nomia longitarsis eboris var. nov. 



Male and female. — Stigma black or reddish black; abdominal 

 bands (except the first in female) clear opaque ivory color. 



Luzon, Nueva Vizcaya Province, Imugan, male (type) : Ben- 

 guet Subprovince, Baguio, female. Both from Baker. Probably 

 a subspecies, but without strong characters. 



Nomia strigata (Fabricius). 



Andrena strigata Fabricius, Ent. Syst. 2 (1793) 311. 

 Nomia strigata Lepeletier, Hist. Nat. Ins. Hymen. 2 (1841) 291. 

 Nomia iridescens "Smith," Cockerell, Entomologist 48 (1915) 177 

 (not iridescens Smith). 



I had formerly supposed 2 that the male of Nomia iridescens 

 differed from the female in having the first five abdominal seg- 

 ments with colored bands, but I now find that there are males 

 and females with (strigata) and without (iridescens) the band 

 on first segment. Some specimens of N. strigata, as is usual in 

 this group of Nomia, have bands which fail to assume the proper 

 color, but then these bands are pallid or reddish, very different 

 from the opaque black hind margin of the first segment in iri- 

 descens. It must be stated, however, that strigata and iridescens 

 are extremely closely allied, and it is by no means certain that 

 they are not forms of a single species. Nomia quadridentata 

 Smith is based on a female that is evidently strigata and on a 

 male of the N. ellioti group. The first and fullest description is 

 that of the female, which is herewith designated as the type. 



Palawan, Puerto Princesa. Mindanao, Davao. Negros, 

 Cuernos Mountains. All from Baker. The Philippine insect 

 agrees with that from Java (Depok, Pelaboeam, Ratoe, Buiten- 

 zorg), collected by Bryant and Palmer (United States National 

 Museum).
