206 PHYTOPHAGA.—SUPPLEMENT. 
5. Agbalus hogei. 
Oblong-ovate, bluish-black ; above obscure purplish or violaceous; antenns and legs fulvous; thorax very finely 
and closely punctured ; elytra strongly and closely punctate-striate, with an obsolete basal depression. 
Length 14 line. . 
Of rather short and broadly ovate shape; the head with some oblong and not very closely placed punctures on © 
the vertex, and an obscure median longitudinal groove; the clypeus rugosely punctured, bounded above 
on each side by a smooth bluish space; labrum and palpi fulvous; antenne extending beyond the middle 
of the. elytra, fulvous, the terminal joints slightly thickened and marked with fuscous at the apex ; thorax 
transverse, convex, the sides strongly rounded and narrowed towards the apex, with a narrow reflexed 
margin, the anterior angles acute but not produced, the surface very closely and finely punctured at the 
sides, more remotely so on the disc; elytra with a rather distinct transverse depression below the base, 
strongly punctured in rows, the sides with two or three strongly raised coste towards the apex, the suture 
also narrowly but distinctly raised; legs fulvous. 
Hab. Mexico, Refugio in Durango (fHége). 
This insect agrees in shape and in its main characters with Agbalus; the specimens 
received are apparently all females. The dark purplish colour and the fulvous antenne 
and legs distinguish A. hégei from its allies from our region. 
6. Agbalus tenebrosus. 
Oblong-ovate, dark greenish-zeneous; the lower joints of the antenne fulvous; thorax transversely convex, 
minutely punctured ; elytra finely and closely semiregularly punctate-striate. 
Length 13 line. 
Head finely and remotely punctured on the vertex; the clypeus more closely punctate, not separated from the 
face, its lower edge concave-emarginate; eyes sinuate at their lower margin; labrum piceous ; terminal 
joint of the palpi robust and rather elongate; antenne not extending much beyond the base of the thorax, 
robust, the lower six joints fulvous (the first piceous above), the others black and much thickened; thorax 
transversely convex, its sides strongly rounded, the anterior margin straight, the angles acute but not 
produced, the surface very finely and rather closely punctured ; scutellum broad, smooth ; elytra slightly 
widened towards the middle, rather short, the shoulders scarcely prominent, the base with a very obsolete 
depression, the surface punctured in closely-arranged but not very regular rows, which are more widely 
separated towards the apex, the interstices flat ; underside metallic greenish ; legs robust, the tibie clothed 
with long fulvous pubescence near the apex; prosternum elongate, narrowed between the coxe. 
Hab. Panama, Volcan de Chiriqui (Champion). 
A, tenebrosus, of which only a single example was obtained, is much more typical of 
the genus than many of its congeners, although the posterior tibial spine, peculiar to 
the male in some species, is here absent; the specimen described is undoubtedly a 
male, it having the anterior tarsi dilated. In the robust antenne and legs and the 
general shape it agrees with Agbalus; the elytra have a slight purplish tint when 
viewed in certain lights. | 
7. Agbalus violaceus. 
Corysthea violacea, Jac. huj. op. p. 154, t. 9. fig. 3. 
According to Lefévre (Ann. Soc. Ent. Fr. 1889, p. 340) this species should be placed 
in Agbalus; but as in my opinion neither this genus nor Corysthea is sufficiently well 
defined (containing species with short, robust, and long filiform antennee and emar-
