and on some Types of Oriental Carabidae. 169 
examined the typeand informed me that the fourth tarsal 
was bilobed. There are two examples in the British 
Museum, which I had already identified as Wiedemann’s 
species : I took one of these to Copenhagen for comparison 
and found that it agreed exactly. Wiedemann’s descrip- 
tion is rather short, and, as no one else has redescribed the 
species, I do so at the end of this paper. 
17. Oodes virens, p. 50. Bengal. 
Chaudoir omits all reference to this species in his Mon. 
des Oodides (Ann. Soc. Ent. Fr. 1882), but this work was 
published after his death. It is identical with his Oodes 
varians (1. c. 352), so that Wiedemann’s name must replace 
his. Chaudoir’s specimen also came from Bengal. I have 
only seen four other examples, viz. two from Assam (Indian 
Museum and Pusa Coll.), one from Burma (my own collec- 
tion), and one from the Philippine Is. (Brussels Museum). 
I compared my own example with both types. 
18. Chiaenius chaleothorax, p. 51. Bengal. 
This species presents some difficulties. Wiedemann 
described a 3 specimen, but in the Copenhagen Museum 
there are two specimens (¢ 9) side by side, the type label 
being attached to the 9. There is a considerable difference 
in the size of the insects, the ¢ being 16 mm. long and the 
2 20 mm.; I do not think that they belong to the same 
species, and I consider the ¢ example to be the type of 
Wiedemann’s species. 
Chaudoir supposed that his C. pubipennis (Bull. Mose. 
1856, ii, 233) was the same species as Wiedemann’s (see 
Mon. des Chléniens, 138), and I took to Copenhagen an 
example, previously compared with Chaudoir’s type, for 
comparison. The specimens do not agree, C. chalcothorax 
($) being a little larger, the sides of the prothorax hardly 
sinuate before the hind angles, its surface more sparsely 
but much more coarsely punctate, the base more evidently 
bordered, the elytra darker and with the puncturation 
more aciculate. The 2 Copenhagen example, in addition to 
the much larger size, has the sides of the prothorax dis- 
tinctly sinuate before the hind angles, with the basal 
foveae larger and shallower than in the 3; the elytra are 
browner in colour, more dilated behind, and more coarsely 
punctate, in addition to which they have a yellow border, 
thus excluding C. macropus Chaud., and its allies. I found 
that I had in my collection a specimen, labelled India, 
apparently agreeing with Wiedemann’s 3; I sent this to
