Mr. H. E. Andrewes on Oriental Carabidae. 475 
Tachycellus lamprus, Bates, Ann. & Mag. Nat. Hist. (5) xvii. 
1886, p. 80= Trichotichnus lamprus, Bates. 
This species, labelled in Bates’s handwriting, differs in so 
many respects from the description, that I think the author 
must have had some other insect before him. I cannot, 
however, find anything agreeing with the description among 
the Carabide taken by Mr. Lewis in Ceylon, and I can only 
mention the discrepancies I have noted. The upper surface 
is glossy and relucent, as mentioned, but blue-black rather 
than enescent. The penultimate joint of the labial palpi is 
plurisetose, not bisetose ; I am unable to detect the punctured 
fovea on the first segment of the abdomen in the @ (charac- 
teristic of Tachycellus and its allies) ; interval 3 of the elytra 
with a well-marked puncture just behind middle. I cannot 
at present see any reason why this species should not be 
included in Morawitz’s genus T'richotichnus, though all those 
hitherto described are confined to N.K. Asia.

Ophionea, Klug. Ent. Braz. Spec. 1821, p. 298. 
This genus was formed for the three species, 1, O. penn- 
sylvanica, L., 2. O. cyanocephala, F., 3. O. surinamensis, L. 
In No. 1 the fourth tarsal joint is simple, and in No. 2 it is 
bilobed. Of No. 3 I have no personal knowledge, but it is 
evidently quite a different insect from the others, and de Geer, 
in Mém. iv. 1774, p. 79, formed for it the genus Colliuris. 
Klug mentions the fourth tarsal joint twice over, but his 
remarks are contradictory: under ‘“ Characteres” we read 
“tarsi articulo quarto elongato,” but under “generis de- 
scriptio” this becomes “ tarsi articulo... quarto brevissimo.” 
A year later Latreille and Dejean, Hist. Nat. & Icon. d’Eur. 
1822, p. 77, published the genus Casnonia, which was not,
