This Hegeter, which seems to be peculiar to TenerifFe, is quite as 

 variable as the last one ; nevertheless its two extremes of form are 

 very easily connected. In the higher regions it is large, broad, de- 

 pressed, and evidently punctulated, and its elytra are wide and par- 

 allel in front and more or less coarsely (though irregularly) trans- 

 versely -sc7'atcJied (or -rimose) ; but as we descend in elevation all 



* Dr. Heer, in the list which he prepared for M. Hartung's vohmie, has cited 

 the H. transversus as found in Fuertevcntura ; but I am satisfied that it does not 

 exist in either of the two eastern islands of the Group (probably indeed not be- 

 yond Teneriffe), and that the error has arisen (as in other instances already 

 commented upon) from M. Hartung's having unintentionally transposed certain 

 of his specimens from the dilFerent islands. Nevertheless tlie species was rightly 

 identified by Dr. Heer ; for he has himself sent me an example referred correctly 

 to the H. transversus. It is, however, comtmmicated as coming from "Lanza- 

 rote," even whilst he publishes the insect as a Fuerteventuran (and not as a 

 Lanzarotan) one ! — another instance of the excessive inaccuracy, displayed alike 

 by himself and M. Hartung, as regards their meagre Catalogue. The different 

 forms of Hegeter (whether species or not) are so unmistakeable, when accurately 

 inspected, and so topographically restricted, that I am convinced that the spe- 

 cimen which he forwarded to me is strictly a Teneriffan one, and that it was 

 probably taken in some part of the Vale of Orotava. In like manner he registers 

 the H. brevicollis as found in both Lanzarote and Fuerteventura, whilst I will 

 undertake to say that it never occurred in either of them. As in the other case, 

 it is a Teneriffan species, with a slightly aberrant state peculiar to Gomera. 

 But as he has not communicated a type identified with the brevicollis, it is cer- 

 tainly possible (in tliis instance) tliat he may have fallen into a mere mistake of 

 names, and that he in reality alludes to a totally different Hegeter— or, more likely, 

 to the Thalpophila plicifrons (wliich at any rate is found in Fuerteventura).
