alxmt disc, and more c()nsj)ieii()iis within lateral marj^ins ; 

 (•1\ tia very dark pniple, less brightly metallic than prothorax, 

 marj^ins ohsennly hlnish jjrcen ; base of mandibles, 

 palpi, and two first joints of antennie reddish testaccons, 

 remaiuin};^ joints of latter and the labrnm piccous. Under- 

 side and legs (except the tarsi, which are dark red) black. 



Head aeicnlate and w ith some faint plications and punc- 

 tures on either side above and Ijetween the eye-;, frontal 

 fovea.' and transverse suture obsolete, the carinic bounding 

 the frons promimntly developed; labrnm very short and 

 cmarginate ; mandibles elongate and liardly arcuate. 

 Antennie subfiliform, short (reaching about one-fourtli the 

 length of elytra), first joint swollen, as long as third, joints 

 abo\e third compressed, and very gradually widening to 

 seventh or eighth. 



Prothurax trajicziform, 3^ mm. wide by 2^; mm. long, 

 truncate at apex, angles hardly produced, rounded, de- 

 j)resscd, sides gently explanate to middle, thence straight to 

 })ostcrior angles, which are bluntly right, base broadly 

 emarginate medially, disc a little convex, median line well 

 dehned, not quite reaching cither apex or base, lateral 

 basal sulci elongate, reaching base, lateral margins within 

 retlexed borders, deci)ly sulcate, the grooves widening out 

 posteriorly, disc aciculate and with more or less seriate lines 

 of remote punctures running longitudinally on either side of 

 middle line, becoming less regular and sparser outwardly, 

 cxcei)t in the marginal grooves, median j)art of apex, lateral 

 basal sulci, and the base itself densely aciculate })unctate. 



Ehjh'ii f-oldercd, base bisinnate, hardly wider than pro- 

 thorax at base, scutellum broadly triangular, humeral angles 

 sharp, subdentate, a little ampliated for a short distance 

 below, siiles parallel for two-thirds the length and gently 

 rounded to and hardly sinuate before apex ; a little convex 

 above, stri:e sulcate, punctate, intervals costate, nearly 

 smooth, the eighth narrower, carinate, and thesj)ace between 

 it anil the outer margins rugosely punctate, the ninth stria 

 not reaching shoulder, very sparsely pubescent about apex 

 and posterior margins. 



Underside glabrous, with remote shallow punctures on all 

 the stcrnie, some coarser jjunctures on the |)rcstcrnum ; 

 venter smooth, except for some rugosities about sides of 

 base. 



It agrees well with the characters given by Lafertc for 

 his genus yEacus {vide vol. i. })age 222, 'Genera des Coleo- 

 j)tcres,' Lacordaire), especially in the shape of the mentum, 

 M hich is exactly as he describes it: " dent nu'diane du menton
