The Group Hydnocerini. — With the exclusion of Ellipotoma, 



Spiu., which belongs to the next subfamily, and Cleropiestus, 

 Fairm., which I have suggested should go in the group 

 Clerini, the present group would now be composed of the 

 following genera: Eurycranus, Blanch. , Hydnocera,Newm., 

 Isolemidia, Gorharn, Lemulia, Spin., Parmius, Sharp, Neo- 

 hydnus, Gorhain, Cephatoclerus, Kuw., and Allelidea, 

 Waterh., with perhaps Ecenus, Cast, Abrosius, Fairm., 

 Emmepus, Motsch., and Theano, Cast., genera which are at 

 present unknown to me. Paupris, Sharp, which is included 

 in the group by Schenkling, is somewhat doubtfully to be 

 placed there, owing to the coarse facetting of the eyes, 

 iiut I do not at present know of a better place for this 

 genus. 



The genus Thanasimodes , Murray, which I have placed 

 next Noto.vus, Fab. (in the group Clerini), differs from the 

 latter only in having the acetabula of the front coxae com- 

 pletely closed in behind. The type, T. metallicus, Murray, 

 a species from Old Calabar, is, I feel sure, identical with one 

 from the same locality described later by Chevrolat, viz. 

 Opilo chloropterus. Opilo cyaneo purpureas, Fairm., is closely 

 allied to it, and there are other African species, including 

 dorsalis, Lucas, yiyas, Cast., and nigerrimus, Kraatz, now 

 placed in Opilo, which agree with T. metallicus in having 

 the front coxal cavities closed in behind, and would therefore 

 be better placed in Thanasimodes. 



It will be seen that L have substituted the name Notoxus, 

 Fab., for Opilo, Latr. ; and some explanation for this is 

 necessary, and the reason also why I have proposed the new 

 name Enoclerus for the genus characterized by Schenkling 

 under the name of Clerus ■(' Genera Insectorum/ Cleridae, 

 p. 48, 1903). 



On the Application of certain Generic Names. 



The name Clerus was first proposed as a generic name by 

 Geoffroy, but since Geoffroy did not in his first work make 

 use of the binomial nomenclature he is no longer recognized 

 as the author of this and of several other names that he was 

 the first to employ. It appears that Fabricius was the first 

 author who at the same time characterized the genus Clerus 

 and made use of the binomial system, and he is therefore 

 admitted to be the author of the genus Clerus. The species 

 included by him in the genus at its first publication, Syst. 

 Ent. p. 157 (1775), were in order as follows : mutillurius, 

 Fab., formicarius, Linn., sipylus, Linn., and apiarus, Linn.
