NEW MICROLEPIDOPTERA FROM HAWAII 103 



group of metallic Xylocopa with dark face in the male, represented by 

 lihrocedri, arizonensis, and californica, belongs to the Pacific coast and 

 the arid southwest, and is not related to the species of tropical Mexico 

 and Central America. A related but distinct group, with light face in 

 the male, is that of X. virginica and texana, with the little-known am- 

 blardi, said to occur in CcJifornia. A marked feature common to both 

 of these groups is the triangular area with strongly pectinate border on 

 sixth abdominal segment of female, h is also to be noted that there exists 

 a variety of arizonensis in which the clypeus of the male has a cream- 

 colored spot (Entom. News, Nov., 1907, p. 395). The mandibles of 

 X. arizonensis, lihrocedri, and virginica are bidentate in the female, not 

 tridentate as in the European X. violacea. The association with Lihro- 

 cedrus (Heyderia) decurrens may be accidental ; but it is interesting to 

 find a member of what appears to be a rather old type of North Ameri- 

 can bees connected with a plant-genus which we know to be an ancient 

 cind now waning member of the flora.

NEW MICROLEPIDOPTERA FROM HAWAII 



By AUGUST BUSCK 



Mr. Otto H. Swezey, of the Hawaiian Sugar Planters* Association 

 Experiment Station, has recently sent to the U. S. National Museum a 

 third large contribution to the knowledge of Hawaiian Microlepidoptera, 

 consisting of 50 bred species, each in liberal and well-mounted series. 

 Most of these are known species or cotypes of new forms described by 

 Mr. Swezey, but the biological facts are all new, and Mr. Swezey will 

 himself igive a complete account of these. He has asked me to determine 

 and describe the following new species. 



Platyptilia lantana, new species. 



Labial peJpi short, dark fuscous, irrorated with yellowish white and 

 with apex of second and of third joint yellowish white. Face and head 

 fuscous. Face without projecting cone. Antennae dark brown dotted 

 with light yellow. Thorax fuscous with posterior edge broadly white. 

 Forewings cleft to apical two-thirds ; segments broad, termen of the first 

 with one of the second with two sinuations ; ground color whitish ochre-
