RHYNCHITES Herbst. 



R. velsif IIS. — Robust, densely clothed with prostrate coarse white pubes- 

 cence; head behind the eyes brassy, elytra violet-coppery. Beak moderately 

 stout, straight, as long as the bead and prothorax, black, slightly flattened 

 externally, strongly punctured, carinate at base, with a frontal puncture, eyes 

 slightly convex; head slightly wider behind, punctured, hairy and black in 

 front, transversely rugose, glabrous and brassy behind. Prothorax black, 

 strongly punctured, narrowed in front, sides broadly rounded, base very oblique 

 each side, obtusely rounded at the middle. Elytra violet-coppery, densely 

 punctured, not striate, the striae being represented only by rows of small 

 distant black dots, from which proceed erect black stiff hairs. Pygidium 

 exposed, punctured, hairy. Beneath brassy, finely punctured and densely 

 pubescent. Legs black, densely pubescent, claws with a long acute tooth. 

 Length 7 mm. 



Sierra Nevada; collected by Mr. H. K. Morrison. The antennae are 

 black, inserted at the middle of the length of the beak, which is with- 

 out lateral grooves or cavities behind the insertion of the antennae. 



ACAIiLES Sch. 

 \, Hubbardi. — Very robust, subpyriform, black, clothed with appressed 

 scales; intermixed bristles so short as to be scarcely perceptible. Beak cylin- 

 drical, curved, without scales, shining, punctured, as long as the prothorax; 

 head clothed with white scales, with a black deep median furrow. Prothorax 

 a little wider than long, very much rounded on the sides, narrower at apex 

 than base, and strongly constricted near the front margin; disc convex, crib- 

 rate, carinate at the middle, ornamented with several small dots each composed 

 of a few white scales. Elytra ventricose, strongly and obliquely dilated behind 

 the humeri, with an obtuse rounded angle; from this callns a short wide fascia 

 extends inwards to the fourth stria where it unites with a small spot on the 

 fourth interspace; there is a narrow undulated band of white scales at the 

 second third of the length, and the declivity is mottled with small spots of 

 white scales; at the base are some spots of velvety black scales; the strise are 

 deep, with large impressed fovese, interspaces very convex. Legs in great part 

 clothed with white scales. Mesosternum deeply seinicircularly excavated. 

 Length 7 mm. 



Crescent City, Florida; found by Mr. Hubbard under Opuntia 

 leaves. This species is quite distinct from any other known to me 

 by the above characters, and is to be placed before .-1. nohilis in my 

 synoptic table, (Rhynch. 240), with the following character : Scales 

 appressed, without intermixed bristles. It is the species to which I 

 have alluded in the remarks under A. nobilis, (p. 2-1:1). 



EISONYX n. g. (Curculionidse). 



This genus belongs to the tribe Bariui, and is related to Microchohis 

 Lee, (Khynch. 303), which it resembles in appearance. By the 

 sino'le claw it bears the same relation to that form as Barilepton does 

 to Centrinus. The pygidium is visible in both specimens, but is, 

 1 think, abnormally protruded.
