128 MADEIRAN COLEOPTERA, 
Genus 155. POGONOCHERUS. 
(Megerle) Steph., Idd. Brit. Ent. iv. 233 (1831). 
The present genus, which is an addition to our fauna since the 
publication of the Insecta Maderensia, contains the smallest Longi- 
corn as yet detected in these islands. It may be readily known by 
its tuberculose and laterally spined prothorax (in which respect it 
resembles Blabinotus), by its deflexed head, annulated antennze 
(which are ciliated with long hairs beneath), and by its posteriorly 
acuminated elytra,—which are curiously truncated, and spined, at 
their hinder apex. The species are for the most part prettily varie- 
gated with dark and light pile,—the former being often disposed 
longitudinally, in tufts. 

381. Pogonocherus hispidus**, 
P. fusco-brunneus pubescenti-variegatus, prothorace ineequali tuber- 
culato ad latera spma media instructo, elytris ob-triangularibus 
apice truncatis quatuor-spinosis, antice late albo-pubescentibus, 
postice nigro-fasciculatis.

» Mils., Longie. de France, 159 (1840). 


P. more or less brown, and variegated with dense decumbent pile. 
Eyes greatly emarginated internally. Antenne as long as (ora 
little longer than) the entire insect, and furnished with long hairs 
beneath ; the joints more or less ringed with white pubescence at 
the base of each,—the apical portion of them being darker. Pro- 
thorax with the sides produced into a robust central tooth ; its 
upper surface uneven, and with a tubercular glabrous prominence 
on either side of the disk. Llytra ob-triangular (being broad at 
the base, and gradually acuminated posteriorly), and truncated at 
their extreme apex,—the outer apical angle of each being produced 
into an acute spine, and the inner one less so; with a greatly 
raised longitudinal line (and the rudiments of one or two more) 
down cach; the anterior half densely clothed with snowy-white 
pubescence (except at the extreme base, where it is olivaceous), 
and the hinder half ornamented with a longitudinal row of darker 
fascicles, on each. Legs variegated. 
An abundant insect throughout Europe, and probably introduced 
into these islands,—from whence I have lately received a pair, 
which were detected by Mr. Mason in Madeira proper (I believe near 
Funchal). They differ in no respect from the specimens of more 
northern latitudes.
