40 Dr. Heiiieken's Description of Hegeter Webhianus. 



Tab. II. Fig. 5. A Female. It is somewhat magnified, and the thighs ai'e 

 proportionally rather too short. The Male has a narrower 

 abdomen, and the sexual organs bent upwards and for- 

 wards. The Young differ only in being more linear, 

 smaller, lighter in colour and less distinctly marked. 

 The false segments are also obsolete, or nearly so. 



Hegeter. (Latreille, Genera, &c. vol. 2, p. 156.) 



Heg. TVebbianus. (nob.) 



Ater, obscurus ; labro, palporum maxillariumantennarumque apicibus 

 fuscis; capite thoraceque laevibus irapunctatis ; thorace postice subsinuuto 

 et ad latera postic^que leviter marginato, angulis acutis ; scutello linear! 

 transverso ; elytris basi et externe marginatis, obsoletissime subsulcatis. 

 Longitudine 4^ lineis. 



Habitat in Insula Nivaria. 



The above insect was sent to me a few weeks back from Teneriffe, by 

 my friend Mr. Webb, (after whom I propose, should it prove new, to 

 name it), but I have not yet learnt any particulars of its habits. It is so 

 precisely in every respect a Hegeter of Latreille, that it would be useless 

 either to figure or minutely describe it. Indeed excepting in size (4i 

 instead of 8i lines), in having the grooves of the elytra but just dis- 

 cernible, in the ehjtra diminishing more gradually in width towards the 

 thorax, and in the latter being subsinuated behind, and less palpably 

 marginated, it approximates so nearly to his Heg. striatus, that, with the 

 addition of the /ew words in italics, the specific character given above is 

 verbatim that of the striatus in the " Genera, &c." And as I conclude 

 the latter, both from its having led to the formation of the genus, and from 

 Lamarck designating it " Akis Hegeter,'" to be the only known species, 

 I have ventured ours in addition. 



genus the Rev. Mr. Kirby, to whom the description and figure have been 

 submitted, is disposed to place it. " If you examine," he says " the true 

 " Ploiaria vngabunda, you will find that it has a bilobed head as in fig. 5. a. 

 " and that the antennae, rostrum, and fore legs, are precisely similar. In fact 

 " there is no prominent difference except that the Madeira species is apterous."
