little more sharply carinate. At most they do not form 

 more than a local race of the Chinese species. 



5. Tachys arcuatus Putz. (Ann. Mus. Civ. Gen. 1875, 

 744). This specimen was taken by Nietner in Ceylon, 

 and is the only one I have seen. Putzeys' description is 

 not a satisfactory one, and he makes no comparison with 

 any other species. 



The colour of the upper surface is dark red, not black, 

 the elytra piceous towards apex; the front red round 

 spot, which he mentions, is non-existent, the hind one is 

 triangular rather than round, and yellow. Joint 2 of 

 the antennae is practically as long as 3. The eyes are 

 very moderately prominent. The frontal foveae are very 

 short and end in a large round puncture a little before 

 mid-eye level. The prothorax is narrow, but nevertheless 

 slightly transverse, the sides very little rounded. The 

 most striking character of the elytra, which Putzeys does 

 not refer to, is the great depth of the first stria, which — ■ 

 except near base and apex — is deeper than in any other 

 species known to me ; the arcuate second stria, which 

 recedes from the first in the middle of the elytron, is also 

 very characteristic. The length is quite 3-5 mm. 



About the size of T. eueides Bates (Ann. Mag. Nat. 

 Hist. (5), xvii, 1886, 153), or a shade larger, colour dark 

 red, not black, joints 5-11 of the antennae fuscous, the 

 apical spot on the elytra smaller and lighter in colour. 

 Head with a wider neck, the frontal foveae punctiform; 

 prothorax less rounded at sides and less contracted behind, 

 the transverse basal sulcus not so deep and formed chiefly 

 by a series of five large punctures ; elytra rather more 

 convex, the two pores placed a little closer together, the 

 first stria much more deeply impressed, the second not 

 p&,rallel with it but noticeably arcuate. 



6. Trechus indicus Putz. (Stett. Ent. Zeit. 1870, 175). 

 Putzeys says at the end of his description, " Mr. de Chaudoir 

 m'en a communique un individu unique ((^) comme venant 

 des Indes Orientales, sans autre designation." The speci- 

 men in question is a (^ and bears a " type " label : on the 

 other hand, Chaudoir was not in the habit of giving away 

 unique examples, there is a locality label " Darj." (Darjihng), 

 and a comparison of the description with the specimen 

 makes it quite certain that this is not really the type, which 

 was no doubt returned to Chaudoir. Mr. Rene Oberthiir, 

 however, tells me that he does not think he has it.
