Eurynotida u. gen. 



In general facies this genus differs wholly from any other 

 of the present tribe, shorter and even broader than any form 

 of Hoplandria^ the middle coxae are closely contiguous, with 

 the mesosternal process extremely short and cuspidiform, the 

 metasternumarcuatO'truncateand not at all projected between 

 them ; the infra-lateral carinae of the head are strong and entire, 

 the maxillary palpi very slender, setose, the antennae slender, 

 subfiliform, the hypomera invisible from the sides and the 

 hind tarsi rather long, slender, with the basal joint as long 

 as the next three combined. We have at present two species 

 as follows: — 



Form very stout, rather convex, shining, not reticulate, minutely, not very 

 closely and indistinctly punctulate, testaceous in color, the head and 

 elytra darker, piceous-brown, the latter nubiliously paler about the 

 scutellum and each testaceous at the outer apical angle, the inner out- 

 line of the pale spot oblique and straight; abdomen with a large nubilous 

 piceous cloud before the tip; legs and antennae pale flavate through- 

 out; pubescence rather long, pale, prostrate but inconspicuous except 

 on the abdomen, where it is longer and intermixed with sparse erect 

 tactile setae; head transverse, small, rapidly and arcuately narrowed 

 behind the moderate and somewhat prominent eyes, convex, onim- 

 pressed, the neck only moderately broad; antennae slender, extending 

 almost to the tips of the elytra, the second joint rather longer than the 

 third, both much elongated, four to ten more or less distinctly longer 

 'than wide and only just visibly increasing in thickness, the eleventh 

 very slender, pointed, almost as long as the three preceding combined; 

 prothorax about twice as wide as long, almost four-fifths wider than 

 the head, parallel and evenly arcuate at the sides, broadly rounded at 

 base, the basal angles well rounded, the surface wholly unimpressed; 

 elytra short, transverse, the base not quite as wide as the prothorax, 

 the suture about as long as the median line of the latter, the sides feebly 

 diverging; abdomen not quite as wide as the elytra, parallel, narrowed 

 slightly at tip, the basal tergites not very obviously impressed at base. 

 Length 2.2 mm.; width 0.87 mm. Texas (Del Rio),— H. F. Wickham. 



ornata n. sp. 



Form, sculpture and pubescence nearly similar, slightly shorter, testaceous, 

 the head blackish, the elytra piceous-brown with the sutural region and 

 external apical angles pale testaceous as in ornata, the abdomen with a 

 similar piceous cloud; head larger, the eyes moderate and similarly 

 somewhat coarsely faceted; antennae with the joints two to four 

 elongate, uniformly decreasing in length, the second more evidently 

 longer than the third; prothorax more than twice as wide as long, the
