CANARIAN COLKOPTERA.

Madeiran confertus — of which indeed the species might ahnost be re- 

 garded as a geographical modification. Apart, however, from obscurer 

 characters, the rather narrower prothorax of the H. congener, which 

 is also a little less rounded, and less coarsely margined, at the sides, 

 combined with its just perceptibly broader eyes (longitudinally) and 

 its almost entire freedom from tubercles on the hinder portion of its 

 elytral interstices (which even in the state "2," from Grand Canary, 

 are coniparativeh/ but ill expressed), wiU serve to separate it from the 

 (equally variable) H. confertus. 



755. Helops carbunculus. 



H. preecedenti similis, sed paulo minor et minus ater (interdum etiam 

 subpicescens) ; prothorace vix longiore, antice convexiore, ad latera 

 minus rotundato, ante angulos posticos paulo minus evidenter si- 

 nuate sed ibidem plus minus lateraliter compresso, angulis anticis 

 acutioribus et sensim magis porrectis, in disco plerumque paulo 

 levins punctato ; elytris vix opacioribus, levins ac magis tenuiter 

 crenato-striatis, interstitiis soepius subdepressis, paulo minus ru- 

 gulosis ac subtilius (sc. subtilissime) punctulatis. 



Var. j3. congesta. Prothorace ad latera ante angulos posticos etiam 

 minus evidenter sinuato, elytris plerumque parum profundius sculp- 

 turatis. [/hs. Palma ct Hicrro.] — Long. corp. lin. 3-4|.

Habitat in TenerilFa, Palma et Hierro, prsecipue in subinferioribus 

 degens. 



This Heh]ps has been observed in TenerifFe, Palma, and Hierro, and 

 was described by myself (in a foot-note of the ' Ins. Mad.') in 1854, 

 from a specimen which was received from the first of those islands 

 by M. Rousset, of Funchal. In Teneriife it is the common species 

 around ^^^ Cruz, and occurs likewise about the Puerto Orotava ; in 

 both of which localities (though particularly the former) I have met 

 with it rather abundantly, and from the latter of which (where it was 

 found by Mr. Gray) it has also been communicated by the Rev. R. 

 T. Lowe and the Barao do Castello de Paiva. In Palma I captured 

 it in the Barranco above S''' Cruz ; and in Hierro, in the district of 

 El Golfo. Although extremely variable, it is on the average a little 

 smaller than the H. congener ; and the larger examples of it are not 



* I examined, when in Paris, M. Brulle's types of his H. transversus (the " de- 

 scription" of which gives no chie whatsoever to the characters of any single spe- 

 cies), and thought it barely possible that they might be conspecific with my H. 

 carbunculus. Nevertheless, as I was far from satisfied about this, I do not consi- 

 der it safe to identify them accordingly without further evidence. I need scarcely 

 add, however, that if a future and more accurate inspection of them should prove 

 the two to be coincident, M. Brulle's name will of course have the priority.
