180 INSECTA MADERENSIA. 



144. Cholovocera Maderae. (Tab. X. fii,'. l.) 



C. rotuiidato-elliptica convexa fernigiiiea glaberrima politissima et fere iinpunctata, protliorace 



postice lato, antennis pedibusque vix pallidioribus. 

 Long. Corp. lin. |. 



Coccinella succina, Heinecken, in lift. 

 Cholovocera Ifadens, Westw'ood, in litt. 



Habitat Maderam, rarissima, — formicarum nidos certe colens : unicum exemplar tantuni vidi, a 

 jigydo Dom. Lowe e rnuseo Heineckeaiano mihi munifice donatum. 



C. roundish-elliptical, convex, pale rufo-ferruginous, exceedingly highly polished, almost impunctate, 

 and perfectly free from pubescence. Head large and wide, with the eyes (which are of a most 

 anomalous structure, being composed of merely a few large facets, set widely apai't upon a convex 

 surface) prominent. Pruthorax transverse and convex ; widest behind, where it is of the same 

 breadth as the elytra, on which excessively minute punctures are just traceable beneath the 

 highest powers of the microscope. Antemue and legs scarcely paler than the rest of the surface. 



A single cxaniplc ouly of this most interesting little insect has hitherto come 

 under my observation, — ^which was captured many years ago (probably near Fun- 

 chal) l^y the late Dr. Heinecken, from whose collection it was presented to me by 

 the Rev. H. T. Lowe. It differs from the Georgian and Sicilian representatives of 

 the group (\\ hich however, as abeady stated, appear to be almost, if not indeed 

 entirely, identical) in its larger size and almost impunctate surface, and in its 

 broader, less apically-acuminated, and more roimded outline,^the prot borax and 

 elytra being widest at their extreme bases, instead of, as there, a little constricted, 

 or pinched in (a peculiarity which, we may just remark, is particularly evident in 

 Holoparamecus, likewise). In addition to which, the third joint of its antennae is 

 not quite so long as is the case with those of either of the above-mentioned species. 

 Like them, it is unquestionably an attendant upon iVnts, — as in fact the general 

 singularity of its structiu'e, more especially of its eyes, would lead us, a priori, to 

 suspect.
