name given to it by its original (and only) captoi*, as Dr. Seitllitz, of 

 Dorpat, to whom I have recently communicated it with my unique (^ 

 of G. socius from the Isle of "Wight, corroborates my opinion that it 

 is a perfectly good and new species. Dr. Seidlitz also informs me 

 that the insect has never been sent to him by Mr. Crotch for examin- 

 ation ; and that my O. socius entirely agrees with his own ^ type. 

 It is curious, that not only the first known Cailwrmiocerics should 

 have come from England (especially as this locality has been doubted 

 by almost every one), but that a second species, of still more curious 

 structure, should be found so far north ; the metropolis of the genus 

 being apparently on the shores of the Mediterranean. 



Compared with G. socius (the only species to which it can be 

 likened, owing to the formation of its antennary furrows, except 

 G. cordicolUs, from which it is at once removed by the shape of its 

 thorax and of the scape of its antennse), G. maritimus is, as a whole, 

 more robustly built, flatter, darker, and much more strongly punc- 

 tured ; and it differs from that species in detail as follows : — the head 

 is wider, with the vertex dark, coarsely granulated, set with stout 

 dark setae, and lighter at the sides ; the eyes are more prominent ; 

 the rostrum (viewed sideways) is deeper, and its median impressed 

 line is not so evident ; the antennary furrows, viewed from the front, 

 are not so open or pit-like ; viewed laterally, they are more regular, 

 rounded on the upper and angulated on the lower edges, and reaching 

 up to the eye itself, the whole furrow being smooth and shining ; the 

 scape of the antennae is set with stouter setae and more evidently 

 granulated, comparatively shorter, very much stouter, less abruptly 

 angulated at the base immediately above the constricted portion 

 (which is rather less abrupt) on the side next the eye, but more angu- 

 lated on the outer side ; the funiculus and club are (comparing the 

 same sexes) very distinctly broader and shorter : the thorax is not 

 so transverse, but more strongly rounded outwardly at the sides just 

 before the middle, and more contracted at the base ; its punctuation 

 is much coarser and more evident ; the light coloured patch of scales 

 at the sides is much wider and less defined on its lower side, covering 

 the whole lower portion of the thorax except a small dark patch, 

 instead of forming a sharp light side line ; and there is no medial 

 lighter line on the disc, which is more depressed : the elytra are 

 flatter, more abruptly declivous behind, less ovate in outline, the 

 shoulders being less sloped off and the sides a little straighter ; the 

 punctuation of the stria? is much coarser and more conspicuous, the 

 setic on the interstices are black, and not so stout or quite so long,
