136 MANDlBtJLATA. — COLEOPTERA. 



Genus LIV. — Bradytus* mihi. 



PfflZ/w moderate; exterjial maxillary with the third joint clavate, shorter than the 

 last, which is oval-truncate; labial with the terminal joint fusiform: labrum 

 quadrate, emarginate: mandibles short, denticulated at the base: mentum 

 slightly notched, the notch with a simple lobe. Antenna; with the three first 

 joints naked, the third joint much larger than the fourth : head broad, rounded; 

 thorax transverse, the sides dilated anteriorly, a little narrowed behind, the 

 base straight, with slightly prominent angles : bodtj convex : elytra slightly 

 emarginate at the tip: wings ample: anterior tarsi of males with three 

 dilated joints. 



Bradytus -\ differs from Amara, with wliicli it lias hitherto been 

 associated, by having the lobe in the notch of the mentum entire, 

 as in Harpalus, the body convex, and the thorax transverse and 

 subcordate. The species are less agile than the other Harpalidse, 

 and affect sandy and open situations. Sturm, in his beautiful 

 Deutschlands Fauna, has given the dissections of Br. consularis as 

 the type of the genus Amara, which shows the great absurdity of 

 selecting any species but the type in illustration of a genus ; as, 

 instead of exhibiting the structure of the genus intended, that of 

 another may be represented; and thus confusion is created, where 

 elucidation is attempted. 



Sp. 1. consularis. Niger, nitidus, suhtus piceus, thorace striolis utrinque duahus 



impressis, elytris crenato-striatis. (Long. corp. 3 — 3g lin.) 

 Ca. consularis. Duftschmid. — Br. consularis. Steph. Catal. p. 28. ls!o. 240. 



Pitchy-black, sometimes slightly aeneous : head smooth : thorax above convex, 

 smooth glossy black, with an abbreviated dorsal channel, and two impressed, 

 more or less punctate, foveae at the base, the outer one terminated by a shght 

 ridge or fold, extending obliquely to the angle : elytra glossy brassy-black, 

 punctate-striated, with an interrupted series of impressions on the margin; 

 the reflected margins testaceous: body beneath rufous-pitchy, the breast 

 punctate: legs deep pitchy-ferruginous: antennae and palpi pale rufo-fer- 

 ruginous. 



Var. /3. ? Broader, the thorax posteriorly with a small oblique smooth impres- 

 sion on each side of the base of the dorsal channel, in addition to the usual 

 foveae. 



* B^alvry,?, tarditas. 

 t This genus is included in the division B of my synoptic table of the Har- 

 palidae, instead of C ; it consequently should be removed to the latter, and 

 may be distinguished externally from Zabrus by the character thorax trans- 

 versus, postice angusiatvs.
