Mr. C. J. Gahan — Notes on Cleridre. 63 



the coxae) ; the tarsal claws usually simple, sometimes with 

 a very small, geuerally obtuse, tooth at the base. 



Although giving as the chief character of the group 

 Cleriui " eyes emarginate in front," Lacordaire included 

 in the group one or two genera in which the eyes are almost, 

 if not quite, entire. Other genera in which the condition 

 is the same have since been added. Thaneroclerus, Lefebv., 

 and its near ally Neoclerus, Lewis, are, from a systematic 

 point of view, difficult to deal with, as they present excep- 

 tional characters : the first tarsal joint has almost disappeared, 

 the next three joints are very short, and, except on the 

 front tarsi, scarcely lobed beiu ath, and the claw-joint is 

 long. In T. buqueti, Lefebv., the type of Thaneroclerus, the 

 eyes, almost entire, are rather small and round, and coarsely 

 facetted ; the prothorax has on each side a distinct line or 

 carina ; the acetabula of the front coxae are closed behind. 

 T. sanguineus, Say, differs from it in having the eyes rather 

 finely facetted, the acetabula open behind, and the pro- 

 thorax without a trace of a lateral carina. The presence in 

 T, buqueti of the lateral carina, of which a trace also appears 

 in Neoclerus, suggests that these two genera should go in 

 the subfamily Corynetinae ; but, on the other hand, the 

 fourth tarsal joint is almost as well developed as the third. 

 Until I can work out their affinities with mere certainty, I 

 must leave them as a separate subgroup in the Clerini. 

 Lyctusoma, Lewis, which 1 do not know, will probably go 

 with them. 



Graptoclerus, Blatsiophthalnnis, Allonyx, and Anthicoclerus , 

 though having the eyes entire or very nearly so, seem not 

 out of place in the group Clerini and would form a small 

 subgroup leading towards the next, in which the eyes are 

 more or less distinctly emarginate, the gular sutures straight 

 or divergent behind, the acetabula of the front coxae gene- 

 rally open, the last joint of both labial and maxillary palpi 

 triangular (with a few exceptions), the tarsal claws simple 

 as a rule or having only a feeble tooth at the base. In the 

 latter subgroup 1 should place the following genera : — 

 Platyclerus, Lissaulicus, Balcus, Aulicus, Phlogistus, Trogo- 

 dendron, Olesterus, Scrobiger, Eburiphora, Zenithicola, 

 Dieropsis, Trichodes, and Eleale. In three of these genera, 

 viz. Platyclerus, Lissaulicus, and Eburiphora, the acetabula 

 of the front coxae are closed behind, the presternum being 

 broad between the coxae, and widely curved out on each 

 side behind. These three genera occur in Madagascar, the 

 rest, in which the acetabula are open behind, are, with the
