278 K. BRENDEL, M. D. 



The names Anops and Typhloops being preoccupied, and Euscmops, 

 proposed by Capt. Casey, means only " nearly blind," I forged, by 

 hard labor, the euphonic name Arianops (PI. IV, fig. 3), from dpc 

 "very," dv " without," u>-<; "eye." 



Decartliroii niariiiiini n. sp. — Form like D. Brendeli, impunctate, pu- 

 besceiu-e white, moderately long, thinly distributed. Lenjftli 1.7 mm. 



The males differ fron) D. Brendeli (PI. IV, fig. 6) by having the 

 antennjBnot modified and the distal third of the intermediate femora 

 simply compressed, forming a sharp ridge above, but no tubercle or 

 spine as in D. exactum. From D. abnorme it diflTers in the whole 

 form, 



Golfview, Miss. ; New Orleans, La. (Hugo Soltau). 



Decartliron scarificafum n.sp. — Has the form o{ D.stigmosnm. Length 

 1.7 mm. Head with two large fovefe on the eye-line, twice as far apart as 

 either from the eye ; two small punctures between the frontal tubercles, connected 

 with the occipital fovese by a straight, faintly impressed line; prothorax sculp- 

 tured with parallel longitudinal scars of equal length, each scar about four times 

 longer than wide, fusiform, the base garnitured with a row of sharp punctures; 

 elytral lines entire, abdominal basal carina, including half the width, appear as 

 a continuation of the discal lines of the elytra. 



Iowa, Cedar Rapids. 



Decartliron seriepuiictalum u. sp. Length 1.2 mm. % . Form, size 

 and color of D. formiceti, but the head has the occipital fovese very large, the 

 frontal depression quite obsolete, the prothorax is less circular, widest rather 

 behind the middle, the base wider and neck narrower; the elytra are visibly 

 punctate in longitudinal rows, which are plainer on and near the sutural lines 

 and on the lateral declivities; the pubescence is rather long and abundant; au- 

 tennal joints decreasing in size from the base to the middle and thence increas- 

 ing; the intermediate femur is not inflated as in D. formiceti, and as it is gauged 

 from the middle, it does not present that enormous spine of D. formiceti, but 

 simply two tubercles. 



Tennessee, H. Ulke. 



Bryaxis foveata Lee— Eed-brown, elytra and legs brighter, impunctate, 

 pubescence very tine. Length 1.45 mm. Head large, frontal ridge angular, in- 

 terantennal space depressed, fovea circular; pubescent and equal in size to the 

 occipital fovese; antennae slender, joint 1 cylindrical, twice as long as wide, 2 as 

 wide as 1, and one-half longer than wide, the following ones much narrower, 3 

 and 5 twice as long as wide; 4 and 6 shorter, 7 still shorter ; 8 as long as wide, 

 9 and 10 trapezoidal, increasing in width and length ; prothorax wider than long, 

 all foveae very large, pubescent, and fully seen from above; elytra confusedly 

 faintly punctulate; abdomen % with the first dorsal one-third as long as wide, 

 the carinffi including one-half of the surface within the border, the middle of 

 the posterior end raised from the base of the second, so as to form a triangular 

 opening ; the second segment not produced as in B. Belfragei, but similarly trans- 

 versely depressed at its base; the third is not modified ; the posterior tibiae are 

 not dilated.
