14 NORTHERN ZOOLOGY. 



DESCRIPTION. 



Body depressed and flat, as in its congeners, piceous ; above densely punctured: mouth rufous: 

 antenna? longer than the prothorax, piceo-rufous: front between the eyes transversely wrinkled : 

 pro thorax convex, with a longitudinal channel; lateral margin dilated, reflexed, and rufous: elytra 

 striated or slightly furrowed, with the furrows and their interstices punctured ; viewed on one side 

 they appear hairy with upright ferruginous hairs; their shoulders and lateral margin are obscurely 

 rufous ; their apex obliquely truncated, and subemarginate : the legs are rufous. 



Variety. B. Piceo-rufous; elytra concolorate. 



(10) 2. * Cymindis unicolor. Unicolorate Cymindis. 



C. (unicolor) punctatissimus ferrugineus . pedibus dilutioribus ; protlioracis margine ltaud explanato. 

 Unicolorate Cymindis, thickly punctured, ferruginous; legs paler; lateral margin of the thorax not dilated. 



Length of the body 3J lines. 



One specimen only taken. 



DESCRIPTION. 



This species greatly resembles variety B of the preceding. It is however smaller and paler ; 

 the prothorax has no longitudinal channel, and its lateral margin is not dilated. 



Family SERICODIAD^. Sericodiadans. 



IV. * Genus SERICODA. Kirb. 



Labrum transverse, subquadrangular : with the anterior angles rounded. 



Mandibles acute, incurved at the apex, not toothed ? 



Labium^ emarginate with a minute tooth in the sinus. 



Maxillce 



Palpi 



Maxillary five-jointed: first joint very minute, second longer than the rest, subcylindrical, 

 attenuated at the base; third obconical; fourth as long as the third, fusiform, truncate; fifth 

 very minute, retractile within the fourth. 5 

 Labial three-jointed: joints nearly equal in length; the two first conical; the last fusiform, 

 truncated. 6 

 Antenna? rather incrassated toward the apex ; scape incrassated ; second joint the shortest, and the 

 third rather longer than the others. 



4 The labium here is synonymous with the mentum of most modern Entomologists for reasons assigned in the Introd. to 

 Ent. (iii, 420. 5th Ed.)
