specimens sent him by Mr. Swezey, and read Dr. Marshall’s 
letter in regard to them. The species were as follows: 
Stenommatus musae, recently described by Dr. Marshall 
from the specimens sent by Mr. Swezey, collected by him in 
banana corms at Kaimuki and thought to be an immigrant, but 
according to Dr. Marshall, not necessarily to be considered as 
an introduced species. 
Stenotrupis sp., a small Cossonid which has been found a 
few times in sugar cane on Oahu. It is not represented in 
the British Museum, and is probably undescribed. 
Lithurgus albofimbriatus Sich. (Megachilidae) and Xylo- 
copa varipuncta.—Mr. Giffard exhibited portions of a tree- 
trunk fence post, collected at Waimea, Oahu, December 27, 
1920, showing channels and cocoons constructed by Lithurgus, 
and Xylocopa; also a cut section of the same post about 2% 
feet long and 8 inches in diameter from which, in 7 days, 19 
males and 25 females of Lithurgus and 22 males and 27 females 
of Xylocopa issued. Also were exhibited slide mounts of mouth 
parts and genital organs of both sexes of Lithurgus. 
Alphitobius piceus—Mr. Giffard exhibited a number of 
these Tenebrionid beetles taken from the above sections of fence 
post. 
New Miscogasterid—Mr. ‘Timberlake exhibited a_ single 
specimen of a parasite reared by Mr. Swezey from flower 
heads of Dubautia collected on Mt. Kaala, Oahu, September 26, 
1920. A large number of Tephritis dubautiae Bryan were 
reared from these flower heads, but there was only one speci- 
men of the parasite, which is a new species of the Miscogas- 
teridae, and is also a representative of an undescribed genus. 
As no other insects were reared from the material, the host 
of the parasite is probably the Tephritis that issued so abun- 
dantly. So far as known, no other Miscogasterid has been 
reared in these islands (except the common introduced To- 
mocera), although the family is one of the few groups of the 
Chalcidoidea represented in the endemic fauna. The species 
are rather numerous and fall into several genera, but speci- 
mens are infrequently met with, and the accumulation of mate-
