CYBOCEPHALID^. 87 



men from Gomera which I have just examined, I perceive that all 

 the tarsi are 4-articulate a fact which would remove the species 

 into the same Section as the European A. marginatvm. 



257. Agathidium integricolle. 

 Agathidium integricolle, WolL, Cat. Can. Col. 100 (1864). 



Habitat Canarienses (Ten.?, Gom.), rarissimum ; exemplaria duo, 

 niortua, fracta, cepit oculatissimus "VV. D. Crotch. 



Likewise a Canarian species, and one which is doubtless distinct 

 from the globulum, though further material is required in order to 

 complete its diagnosis for it is somewhat remarkable that the only 

 two examples which have yet been detected are both of them exceed- 

 ingly imperfect. They were found by Dr. Crotch one of them 

 (during the spring of 1862), I believe, in Tencriife, and the other 

 (during the summer of 1864) undoubtedly in Gomera*. 







Fam. 10. CYBOCEPHALID^E. 



Genus 77. CYBOCEPHALUS. 



Erichson, in Germ. Zeitsch. v. 441 (1844). 



The affinities of this little genus have been, and still are, the sub- 

 ject of dispute. In my ' Ins. Mad.' I assigned it to the Anisotomidce 

 (as then broadly denned), and gave reasons [vide p. 483] which 

 seemed to me, at the time, to be sufficient for indicating its approxi- 

 mate position. But as I there enunciated it as a new group (Stayo- 

 nomorplia}, being unaware that it was already acknowledged under 

 the name of Cyloceplialus, I of course did not think of referring to 

 the diagnosis of the latter in order to ascertain what had been said 

 by others on its supposed relationship. So that it was not until I 

 had gathered the information that StagonomorpTia and Cybocephalus 

 were identical, that the opinion of Erichson, who had placed it in 

 the same family as Nitidula, became known to me. Yet, acting on 

 the assumption of Erichson's usual accuracy, I endorsed his views in 



* Of the latter island there can be no question ; for in a letter now before me, 

 received from Mr. G-. R. Crotch whilst collecting in Gomera, he adds the follow- 

 ing short remark concerning the A, integricolle : " one body only ! which is most 

 extraordinary." And indeed it is through the certainty of this habitat that I feel 

 it just possible that Dr. Crotch's former specimen may perhaps have been Go- 

 meran likewise ; for he could not recall where it was, in Teneriffe, that he met 

 with it. Nevertheless it was certainly amongst his Teneriffan material on his 

 return (in 18(32), and I have no other reason than the above for querying its 

 locality.
