Wings rudimentary, the front pair about as long as the thorax, 

 the marginal vein very long, reaching nearly from base to 

 apex and clothed with many long bristles. 



A single specimen taken at Kilauea in July, 1906, ia 

 probably a distinct species ; it appears to be larger and wider, 

 and is darker in color ; the scape of the antennae is altogether 

 dark, or at most a little rulescent. The thorax is not aeneous. 



Hab : Oahu and Hawaii (var. peles) . 



Dr. Perkins said that in his description of M. Jmwaiiensis, 

 he did not indicate the location of the type and did not con- 

 sider it necessary, among other reasons, because the specimens 

 could not be preserved in satisfactory condition for subsequent 

 comparison. 



An Omiodes Eg^g:-Parasite. 



Trichogramma prestiosa Riley [Hymen.] 



BY OTTO H. SWEZEY. 



On the leaves of wild bananas growing in a gulch near the 

 upper part of the sugar plantatiouj at Honomu, Hawaii, I ob- 

 served some caterpillars of a species of Omiodes not as yet to 

 be determined till the caterpillars have matured.* I also found 

 several batches of eggs which proved to be the same species. 

 Very few caterpillars hatched from these eggs, however, as they 

 were nearly all parasitized, the parasites emerging March 25- 

 30. There were 1 to 3 per egg. They gnawed out before their 

 wings had expanded. 



I referred specimens to Dr. Perkins, who, on comparing 

 them with the original description of Trichogramma pretiosa 

 finds it is apparently this species. I have since observed them 

 at the Capitol grounds, Honolulu, in the act of ovipositing in 

 eggs of the palm leaf-roller (Omiodes blackburni). I take it 

 to be the first record of their presence here. I do not know 

 whether Mr. Koebele introduced them, or whether they have 



* On maturity, these proved to be a new species, which has been 

 described by Mr. Swezey under the name Omiodes nieyricki. Bull. V,
