40 Dr. Heineken’s Description of Hegeter Webbianus. 
Tas. II. Fig.5. A Female. It is somewhat magnified, and the thighs are 
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.

Heg. Webbianus. (nob.) 
Ater, obscurus ; labro, palporum maxillarium antennarumque apicibus 
fuscis; capite thoraceque leevibus impunctatis ; thorace postice subsinwato 
et ad latera posticéque eviter marginato, angulis acutis; scutello lineari 
transverso ; elytris basi et externé marginatis, obsoletissimé subsulcatis. 
Longitudine 44 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 | 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 (44 
instead of 84 lines), in having the grooves of the elytra but just dis- 
cernible, in the e/ytra 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 few 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 hic 
I have ventured ours in addition.

submitted, is disposed to place it. ‘If you examine,” he says “the true 
“« Ploiaria vagabunda, you will find that it has a bilobed head as in fig. 5. @. 
“and that the antenne, rostrum, and fore legs, are precisely similar. In fact 
“ there is no prominent difference except that the Madeira species is apterous.”
