at the lateral margin, behind the base, testaceous. Legs testaceous. Length 

 .22— .24 inch; 5.5— 6 mm. 



Male. — Anterior tarsi with three joints slightly dilated and beneath biseriately 

 squamulose. Anal segment with one seta each side. 



Female. — Tarsi slender. Anal segment bisetose each side. 

 Occurs in the Gulf States and the Carolinas. 



DROmil S Bon. 



This genus is typical of a group, called by Chaudoir the Dromiides, 

 which seems very closely related to his Callidides as both groups are 

 defined. In examining the ligula it will be observed that all the genera 

 have that member bordered in front by a membrane which is an exten- 

 sion of the paraglossae, incomplete however in Metabletus. Dromius 

 makes an exception, there is no membranous border whatever, at least 

 in D. piceus. 



In Dromius the palpi are slender, the tarsi slender with the fourth 

 joint not bilobed nor emarginate, the ungues more or less serrate and 

 the mentum without tooth. 



In our fauna but two species occur, very dissimilar in their general 

 aspect and almost generically distinct. In Europe the species are moder- 

 ately numerous and in form other characters supply the missing links in 

 our small series. They are : 



Entirely piceous. Thorax broader than long, trapezoidal. Elytra nearly parallel, 

 humeri distinct, body winged. Palpi distinctly pubescent pice IIS Dej. 



Pale testaceous, head black. Form slender. Thorax a little longer than wide, 

 very narrowly margined. Elytra elongate, gradually broader behind, humeri 

 obliterated, body apterous. Palpi not distinctly pubescent atriceps Lee. 



D. piceus Dej. — Piceous, moderately shining. Head distinctly longitudi- 

 nally wrinkled above the eyes. Thorax trapezoidal, wider than long, narrower 

 at base, sides moderately arcuate and margined, the margin moderately reflexed, 

 hind angles obtuse, median line nearly entire, surface slightly, transversely 

 wrinkled. Elytra oblong, parallel, surface striate, striae not distinctly punctured, 

 intervals slightly convex, dorsal punctures not evident. Body beneath piceous, 

 smooth. Length .26 — .30 inch; 6.5 — 7.5 mm. 



Male. — The anterior tarsi of the male are slightly dilated, the first three joints 

 biseriately lamellate beneath. The anal segment is slightly emarginate at middle 

 and on each side are three setigerous punctures. 



Female. — Tarsi slender. Anal segment plurisetose each side. 



This species extends from the Atlantic region to the Pacific by the 

 northern line. In the eastern region it does not appear to extend further 

 south than North Carolina. 



D. atriceps Lee. — Pale yellowish testaceous, head nearly black. Head 

 smooth. Thorax trapezoidal, as long as wide, slightly narrowed behind, sides 

 feebly arcuate in front and very narrowly margined, hind angles obtuse, median 

 line rather deeply impressed, surface smooth. Elytra broader behind, humeri
