LONGICORNIA. 329 
Sphenothecus trilineatus (p. 84). 
To the localities given, add:—Muxico, Almolonga (Hége). 
Nearly all Herr Hége’s numerous specimens differ from the typical form as figured 
by Dupont in the lateral white stripe of the elytra being broad and reaching the apex. 
An example of this variety in the Sallé collection is labelled “ S. lateralis, Chev., 
Mexico.” The specimen ticketed S. tomentosus, Dup., in the same collection is a further 
varietal development, in which the lateral white stripe is still broader (leaving only a 
very narrow margin of the black ground-colour) and the central black stripe shows the 
commencement of a division into two. 
Sphenothecus bivittatus (p. 84). 
To the Mexican locality given, add :—Monclova in Coahuila (Dr. Palmer). 
Sphenothecus picticornis (p. 84). 
To the locality Mexico, add:—Puebla, Cuernavaca (Saldé). 
Sphenothecus cyanicollis (p. 85). 
To the locality Mexico, add :—Vera Cruz (Saddé), Almolonga (Hége). 
8. Sphenothecus luteicollis.

postice g gradatim recte angustatis, Q elongatis oblongis, apice truncatis, supra confertim punctatis 
utrinque costis validis levibus tribus ; mesosterno triangulariter porrecto ; antennis quam corpus ¢

Hab. Mexico, Guanajuato (Dugés, coll. Sallé). 
Named Ischnocnemis luteicollis, Dugés, in the Sallé collection, but apparently not yet 
described by its namer. Although it has much similarity in form and colours to 
I. costipennis 2, it cannot be referred to the genus Jschnocnemis, on account of its 
elevated and prominent mesosternum, which is the only constant character that 
distinguishes Sphenothecus from Mannophorus and Ischnocnemas. 
MUSCIDORA (p. 85). 
As remarked above under the genus Deltaspis, Muscidora tricolor, Thoms., may 
possibly be the same species as Deltaspis nigripennis; if this should prove to be the 
case, and the slight characters which distinguish D. nigripennis from the other species 
of Deltaspis be considered insufficient for generic separation, the name of the species 
would stand as Deltaspis tricolor, Thoms. (D. nigripennis, Bates).
