447 
seen were reared by Koebele in Honolulu in the summer of 1900 
from the eggs of Omiodes blackburni (Butler) (U.S. Nat. Mus.). 
132. Megaphragma mymaripenne Timberlake. 
A few specimens of this remarkably minute species were 
taken by Mr. Pemberton, who found them associated with a 
thrips in the forest at Mountain View, Hawai, late in January, 
1920. 
My MARIDAE. 
133. Alaptus immaturus Perkins. 
Recorded by Dr. Perkins in 1910 from Oahu and reared as 
early as January 6, 1905, by Mr. Terry at Oahu Sugar Com- 
pany. There seems to be no doubt that it was unintentionally 
introduced from Queensland at the time that the leafhopper egg 
parasites were being established. It was taken at Hilo, Hawaii, 
on March 8, 1913, by Mr. Swezey. 
134. Alaptus globosicornis Girault. 
Recorded by Girault from Honolulu on a single specimen 
taken August 3, 1900, and the variety hawatiensis was based by 
him on this specimen. Specimens that I have seen reared from 
the eggs of the common wingless Psocid that infests insect col- 
lections (Atropos divinatoria) are uniformly greyish, with the 
abdomen paler. In life they are decidedly blackish in color, with 
the abdomen much more dilutely pigmented and appearing trans- 
lucent dusky whitish, especially in the male. This coloration 
agrees reasonably well with the original description of globost- 
cornis. The Alaptus recorded by Mr. Swezey from Psocid eggs 
in the nests of Megachile from Koko Head, Oahu, I believe 
must be this species, as I have reared specimens under the same 
conditions. The male has the second funicle joint distinctly 
smaller than the joint on either side. One male was taken by 
Mr. Osborn at Hakalau Plantation, Hawaii, in May, 1914. 
135. Alaptus sp. 
One female taken by Mr. Osborn at Hakalau Plantation with 
the male of globosicornis recorded above and two males taken 
by Mr. Swezey on a window in Honolulu, November 28, 1915, 
belong to a species heretofore unrecorded from the Islands.
