Eurohweria compressiceps, sp. n. 



2 . Testaceo-brunnea ; capite nigro, elongato-arcuato, lateraliter 

 compresso, latitiidine duplo lougiore ; pronoto loogitudine paiillo 

 latiore ; segmeiito dorsali secuiido transverse bicarinato ; pygidio 

 eloiigato, angusto. 



(S . Niger ; mandibulis basi, clypeo macula basall utriuque, pronoto 

 margine anteriore iuterrupto et margine posteriore, mcsopleuris 

 linea antice, postscutello, segmentisque dorsalibus 2-4 macula 

 utrinque albidis : abdomine rufo-ferrugineo ; alis subhyalinis ; 

 clypeo elongate, cariuato, apice emarginato; antennis brevis- 

 simis ; pronoto antice emargiuato ; hypopygio trispinoso. 



Long,, 2 4 mm., d" 6 mm. 



? . Head sliinin^, veiy strongly compressed laterally, 

 arched, twice as long as broad, smooth and shining ; eyes 

 very small, touching the base of the mandibles. Thorax and 

 median segment finely but not closely punctured ; -pronotura 

 a little broader than long, subrectangular, as long as the 

 scutellum and median segment combined, and as broad as 

 the head. Abdomen almost smooth ; the segments rather 

 narrowly depressed on the apical margin, more broadly in 

 the middle than at the sides ; second dorsal segment with 

 two strong transverse carinse, the apical margin less strongly 

 raised, forming a third. Pygidium long and very narrow. 

 Intermediate and posterior tarsi slender. 



(J . Clypeus long, as long as the greatest breadth, shallowly 

 emarginate at the apex, with a median longitudinal carina, 

 the labrum exposed. Head, thorax, and median segment 

 finely and closely punctured ; antennae no longer than the 

 thorax without the median segment, of even thickness 

 throughout, as far from the eyes as from each other, the 

 interantennal carina almost transverse and not very promi- 

 nent. Pronotum as broad as the head, widely emarginate 

 anteriorly ; a very deep hollow in front of the mesopleurse 

 for the reception of the anterior femora. Scutellum convex^ 

 subtriangular, rounded at the apex, with a deep transverse 

 groove at the base, rather sparsely punctured. Median seg- 

 ment rounded, not truncate. Abdomen scarcely longer 

 than the head, thorax, and median segment combined, 

 tapering slightly towards the extremities, especially towards 

 the apex ; the segments strongly constricted at the base. 

 Hypopygium with three spines, the median sj)ine the longest. 

 Third abscissa of the radius longer than the second; the 

 second recurrent nervure received at about one-sixth from 

 the base of the third cubital cell. The spine at the angles of 

 the sixth ventral segment is short, but quite distinct.
