4.— Anterior tarsi short, first joint with very long process beneath. ...Coelus. 



2. — Antennse ]ong and tarsi simple as in Coniontis EusatAns. 



Coniontis is the only genus in which the margins are not fimbriate, 

 and Eusffttus has the posterior angles of the thorax prolonged. 

 Two species are known to belong to this genus. 



Color piceousjsurfaee slightly shining, elytrasparselypunctured..puiictulaf a. 

 Color ferruginous brown, opaque, elytra with murieate punctures..niurieata. 



'-' C. piiiietulata, n. sp.— Oblong oval, robust, piceous, moderately shining. 

 Head moderately densely punctured, with extremely minute punctures inter- 

 mixed. Antennffi pale castaneous, last four joints paler. Thorax moderately 

 shining, moderately densely punctured, especially to%vard the sides, intervals 

 with extremely minute punctures. Elytra less densely but more coarsely 

 punctured than the thorax, obsoletely rugulose. Trosternum coarsely punc- 

 tured, side pieces coarsely longitudinally strigose. Body beneath and abdomen 

 sparsely punctured and shining. Epipleuraj smooth, basal third concave. 

 Thoracic and elytral margins fimbriate with short yellowish hairs. Length 

 .40— .56 inch ; 10—14 mm. 



The general appearance of this species is not unlike Coniontis lata, 

 Lee, its form being almost precisely identical. 



C. inurleata, n. sp.— Oblong oval, robust, ferruginous brown, opaque. 

 Head densely and moderately coarsely punctured. Thorax densely punc- 

 tured, punctures denser and coarser at the sides, each puncture bearing a 

 short yellowish hair. Elytra opaque, sparsely murieately punctured, each 

 puncture with a short erect hair. Prosternuni sparsely murieately punctured, 

 side pieces longitudinally strigose, body beneath and abdomen sparsely punc- 

 tured. Legs ferruginous. Epipleur^ at base concave. Margins of body fimbri- 

 ate with short yellowish hair. Length .28— .40 inch; 7—10 mm. 



This species has nearly the form of Coniontis obesa. It differs from 

 the preceding not only by the characters given in the table, but also 

 by the persistence of the hairs of the surface. The two species differ 

 also in the length of the process of the first tarsal joint, in the present 

 species the second joint and a portion of the third are concealed, in 

 the preceding species the second only. It is probable that the punc- 

 tures of the preceding species bear short scale-like hairs, which are 

 very easily removed, as is the case with some Coniontis. 



The two species were collected by Dr. Edward Palmer on Guada- 

 lupe Island.

Specimens which I am unwilling to separate as distinct from this 

 •species, differ in having the elytral strige more distinctly impressed 

 and the interstitial tubercles less distinct. The specimens are some- 

 what larger in size but vary in this respect from .32 to .54 inch; 

 8 — 14 mm.
