Having only a single specimen of this insect, for which, and an 
extensive collection of Coleoptera made on the coast of Chinese 
Tartary, I am indebted to Arthur Adams, Esq., R.N., I have not 
attempted to extract its oral organs; but, judging solely from the 
characters that remain, I do not see that it can well be referred to 
any of the numerous groups described by M. Lacordaire. The habit 
in some respects suggests Stenosine ; but the clavate antenne, ciliated 
tarsi, spurred tibize, and retracted head are at variance with that sub- 
family. In its scaly clothing it is similar in character to Lewhenum 
pulchellum, but more delicate ; and this, in conjunction with its tarsi 
and trigonate anterior tibie, induces me to refer it, although doubt- 
fully, to Opatrine.
