INSECTA MADERENSIA. 339 



and nodules, those behind the middle being the largest ; with the suture, and with a transverse, 

 more or less anteriorly-convex, postmedial patch, common to botli (usually a good deal suffused 

 behind, and sometimes continued to the apex, — being bounded in front only by a somewhat 

 darker portion of the surface), more or less distinctly paler. Antenna and legs rather more fer- 

 ruginous, and somewhat less variegated, than in the preceding species. 



Smaller than any of tlie foregoing species, and readily distiaguislied by its ashy- 

 white suture and the form of its postmedial patch, which assumes somewhat the 

 shape of that which constitutes one of the chief features of the A. terminalis, — 

 ha\'ing a tendency, as in that insect, to be convex in front (iastead of concave), and 

 to be more or less suffused behind into the apes. It is, apparently, very rare, the 

 few specimens which 1 have hitlierto seen having been captured by myself in the 

 same localities as the A. dispar, and usually in company with it. 



262. Acalles globulipennis, Woll 



A. ovatus, squamis nigro-brunneis variegatus ; prothorace convexo transversim setuloso-subtuberculato, 

 ad apicem sub-bifasciculato-setuloso ; scutello hand observando ; elytris punctato-striatis valde 

 convexis, ad latera rotundatis, fascicuUs rainutis setosis nigris (prjesertim post medium, fasciam 

 arcuatam nigrescentem efficientibus) instnictis, plaga lunulata communi subapicali (interdum ad 

 apicem sufFusa, sed antice semper nigro-terminata), et macula subscutellari, plus minusve distinctis, 

 ornatis.

Habitat in locis graminosis humidis per Maderfe regioncm sylvaticam, testate rarior. 



A. ovate, sparingly variegated with brownish scales. Rostrum as in the previous species. ProtJiorax 

 with scarcely any indications of a dorsal channel, but, when denuded of its scales, with a very 

 obscm-e central line or ridge; convex behind, and with two tolerably distinct setose fascicles 

 across the central portion (the two lateral ones being almost obsolete) ; produced, and setose, at 

 the apex, where the setae arrange themselves into two ill-defined fascicles. Scutellum obsolete. 

 Elytra punctate-striated ; exceedingly convex, and with the sides greatly rounded ; without either 

 ridges or nodules, but with several minute fascicles of dark setae, those behind the middle being 

 the largest, and arranged transversely so as to form a dark arcuated postmedial band ; with a 

 transverse, lunulate, abbreviated, sub-apical patch, common to both (and generally more or less 

 suffused behind into the apes, but bounded in front by the postmedial arcuated band of black 

 fascicles), — and with a patch about the region of the scutellum, both more or less distinctly 

 paler. Antenna and legs as in the last species. 



An exceedingly distinct and very interesting little Acalles, and one which 

 departs in many respects from the ordinary Madeiran type, — at the same time 

 making an approach towards the small representatives of more northern latitudes. 

 It may be at once recognised from the remainder of the genus here described by 

 its short ovate outline, by its very convex, inflated and subglobose elytra, and by 

 the minute fasciculated tufts of black setse (with which it is beset) supplying the
