contracted behind. The colour is variable, some specimens being 

 entirely ferruginous with very slightly darker club to the antennae, 

 others are darker with pitchy head, thorax, and antennal club. In the 

 var. suhglohosa the body is short-oval and more convex than in the type, 

 and the thorax is less contracted behind. The colour is entirely ferru- 

 ginous, sometimes including the clul) of the antennae, or with the head 

 and thorax pitchy (var. bicoJor). The striiie of the elytra are generally 

 rather more finely punctured than in the typical form. It is very hard, 

 however, to give a definite name to many intermediate forms between 

 the typical one and v. suhglohosa. In both the posterior tibia is rather 

 variable in shape in the J* , the cuiwatures — especially the basal one, 

 which may be practically absent — being much less marked in small 

 individuals. A typical specimen of the var. ohesa is easily distinguished 

 from the above. It is more parallel- sided, with the thorax more ample ; 

 the club of the antennae is broader, with the last joint broader in pro- 

 portion, and is light-coloured ; the striae of the elytra are more strongly 

 and less closely punctured ; and the til)iw are more dilated. In the ^ 

 the posterior tibiae are more strongly bent. I have seen a few examples 

 which seem to be quite intermediate between this and the typical form. 

 There is also a fairly constant form which somewhat resembles a very 

 large specimen of v. suhglohosa in shape, and in having the club of the 

 antennae narrower, but with the posterior tibiae of the i^ as strongly 

 bent as in v. ohesa. It is one of the forms which give rise to such great 

 difficulty in this species. Since writing the above, Mr. Champion 

 has called my attention to a short note just published by Grerhardt 

 (Deutsche Ent. Zeitschr., 1911, Heft III, p. 34'0). He gives two or 

 three further characters for L. ohesa, and states that he believes it 

 to be a good species. I do not find these new characters any more 

 constant than the others, and they are no help in the determination of 

 the curious intermediate forms. 



L. algirica. — This is a somewhat unsatisfactory species, and might 

 be regarded as yet another variety of L. duhia. Typically it is con- 

 siderably smaller ; the thorax is more strongly contracted behind, its 

 punctuation and that of the striae of the elytra is finer, and the punc- 

 tures are placed fiirther apart in the latter. The club of the antennae 

 is always of a light colour, but the thorax is sometimes darker than the 

 elytra (v. rdgrlceps, Fleischer). The (^ has the posterior tibiae very 

 slightly bent inwards towards the apex. As stated above, this species 

 has been confounded with L. hrunnea by Dr. Fleischer, biit is easily 

 distinguished by its diiferently shaped thorax, more rounded sides of 

 elytra, and more remotely punctured striae of the same, the shorter
