June 1899.] Casey : On American Coccinellid/E. 95 



Body nanower and oval, more strongly convex, the pronotum similarly colored but 

 without a pale apical margin or medial spur, the oblique lateral spot not reach- 

 ing the base in the type, but vfiih a minute detached spot at the basal angles ; 

 elytra with a large pale spot having a straight transverse base, from the ex- 

 tremities of which anteriorly the outline is evenly semi-circular. Length 4.8 mm. , 



width 3.75 mm. New Mexico (Las Vegas) fenestralis, sp. nov. 



One of these species was described by Mulsant under the name 

 biiwtata Say (^=-affiius Rand.), which belongs to Hyperaspis, and the 

 ocuhita of Fabricius, to which they were referred by Crotch, is de- 

 scribed as having a large rounded pale spot at each side of the pro- 

 notum, and must therefore apply to some other species, possibly of 



Ncda.

The species which I have ventured to assign to this genus are 

 rather small in size and have a distinctly oblong-oval form, with irreg- 

 ular elytra] ornamentation. Those before me may be recognized by 

 the following characters : — 



Pronotum with three spots forming a central posteriorly pointed triangle, the posterior 

 the smallest and elongate-oval, the anterior each with a small spot attached 

 antero-externally, also with a larger irregular basal spot at the middle of each 

 side and another subtriangular at the middle and lateral eighth, some or all of the 

 spots generally united, forming an irregular design with a large M- shaped central 

 figure ; scutellum black ; elytra a little longer than wide, somewhat broadly 

 ogival at apex, distinctly but not very unequally punctate, pale in color with a 

 piceous-black design, the most conspicuous feature of which is a longitudinal and 

 slightly oblique vitta from the callus to apical fifth, the two united transversely 

 across the suture behind and at basal two-fifths, and with a subcontiguous spot 

 externally at the posterior, limit ; in the most developed form the entire elytra are 

 black, with a pale bpider dilated internally at the middle, a large discal spot be- 

 hind the middle and a- hasail fascia irregularly dilated ; in the paler forms the 

 dark fascia at two-fifths is broken up and all the lines much reduced in width ; 

 under surface and legs pale -reddish-brown, the prosternum, hypomera, median 

 parts of the mes. > and mclaitems, epipleura; and entire parapleural of the hind 

 body pale yellow ishrwhite. ■• Length 4.0-5.0 mm. ; width 3.0-3.5 mm. Massa- 

 chusetts, New In-ey and Wisconsin (Bayfield) ; [_< oncinna/a Melsh., contcxta 

 Muls.] /v; picta i?(7W. 



Pronotum similar, e\rr]it that thck sublattral spot is feebler and usually disintegrated ; 

 body similar in form and with but slightly feebler punctures but smaller and with 

 the dark design of the ^\xa imler in-color and less developed, the external spot near 

 the posterior extremitji.of the vitta frequently prolonged irregularly to the side 

 margin. Length 3.7-'3.-9- mm. ; width 2.6-2.9 mm. California (Alameda and 

 Siskiyou Cos. ) ./: minor, sp. nov. 



Pronotum similar but relatively smaller and with the black design more irregular, 

 with a few black points at the middle of each side of the apex in addition ;
