120 THE ENTOMOLOGIST. 



with Erichson's descriptions. His insects have not, I believe, 

 been ve-foimcl since his time. 



Anisotoma ovnala. — Mr. Rye has restored Stephens's name, 

 but he only described the colour, having no knowledge of its 

 real differences from Anisotoma calcarata in the thorax and 

 posterior femora ; hence M. Fairmaire must be regarded as 

 the founder of the species. The colouring, moreover, is 

 common to A. dubia and A. calcarata at times, and is not 

 constant here. 



Liodes axillaris. — This species was introduced by me on 

 small examples of L. humeralis, in which the tarsi were less 

 developed, and the femora simple beneath, in the male ; but 

 in the true L. axillaris the gemination of the striae is much 

 more apparent, and the elytra are glabrous. 



Clarabus punctulum. — The four species of Clambi seem 

 found nearly all over Europe, two being pubescent and two 

 glabrous. The present one differs from its ally, C. minutus, 

 in being about half the size, and gradually attenuate behind. 

 The coloration is, moreover, different in the normal form, but 

 it varies considerably. 



Sphserius. — This name has been used on several occasions, 

 both in insects and in other groups ; hence I have retained 

 Kolenati's name, given only a few years later. 



Trichopteryx. — I have followed M. Motschulsky and Mr. 

 Wollaston in altering this name, and conceive that it is in 

 accordance with the law of priority, though changes are 

 always to be regretted. The numerous changes in specific 

 nomenclature have been noticed already by Mr. Matthews. 

 He, however, appears to consider it unnecessary to change 

 M. Thomson's name, but the same name should never recur 

 in the same family, if possible, especially when, as here, all 

 had been united in a single genus. For the same reason 

 I have used Aube's name for the Ptilium trisulcatum, as 

 Linneus first gave that of minntissimus to an Acrotrichus, 

 and was folloM'ed by Marsham ; hence Weber's could not be 

 adopted. 



Olibrus liquidus. — Mr. Wollaston has restored Stephens's 

 name to this species, but the description distinctly speaks of 

 one sutural stria, which is a character of O. geminus. Mr. 

 Rye has employed Erichson's name. The species is pro- 

 bably a race of O. bicolor, but the type-form does not occur
