One female, Kongaiis in August. Professor Cockerel! also brought 

 home a male from Japan. This latter specimen, together with six 

 others from Japan now in the National Museum collection, exhibits 

 decided variation in size and in pronotal coloration, the median stripe 

 of the pronotal disk being continuous to the posterior margin in some 

 specimens while in others it falls noticeably short of that margin, and 

 in some specimens, especially noticeable in one female examined, this 

 stripe is narrower than common, being about as in Indian specimens 

 determined by Mr. Hebard as Blattella cognata Brunner. 



Family ACRIDIDAE 



Subfamily Tetriginae 



ACRYDIUM SIBERICUM Bolivar 



Tettix sibericiis Bolivak, Ann. Soc. Eat. Belg., vol. 31, 1887, pp. 187, 258, 265.

One female nymph from Amagu on the Kudia River perhaps be- 

 longs here. The fastigum of the vertex extends decidedly further 

 anterior of the eyes than in tho specimens determined above as 

 siberimm.

Two males in July, one at Preobrugeniya Bay and one at Barhat- 

 naye near Kongaus, and one female at Kongaus in August. 



GOMPHOCERUS SIBERICUS. var. KUDIA. new variety 



Male. — Structurally very much like typical sibericus, with the ante- 

 rior tibiae greatly swollen, as characteristic of that form. The size 

 is, however, so much greater that a varietal name seems almost a 

 necessity. The thorax in the two specimens examined is almost 

 black, much darker than usual in typical sibericus, but this is per- 

 haps subject to variation.
