tiihert-k's widely sepaiatiMl ami mn(U'i-at(.'ly ckviiteil. I'^vcs miiiuto, 

 with ooaise facets, placed mai- the middle 'riiorax ol' about equal 

 lengtii anel breadth, roumlid and widest just IxdVne the middle, le.ss 

 nari'owed behind tliaii in front, wheie it is nariowei- than tlie head, 

 without perceptible punetatiou; lateral foveae large, indistinctly pro- 

 longed anteriorly, united to the deep transverse basal fossa, discal gi'oove 

 moderately broad and deep and attaining the apex. Elytra suboblong, 

 slightly narrowed towards the rounded slioulders, rather bidadrr and a 

 third longer than th>' thorax, apparently smooth; sutural striae broad, 

 deep and foveiform at the base, and just behind it appearing duplicate; 

 the dorsal nearly similar, but becoming shallow behind; intei-stices 

 carinate. Ilind-body hardly as long as tlie elytra, basal three segments 

 subequal, the others deHexed. 



Legs moderately elongate; intermediate tiljiae rather thicker and 

 more curved than the others, somewhat notche<l at the extremity, the 

 outer angle slightly prolonged, the inner shorter, angtilate and slightly 

 projecting inwardly. 



Antennae rather slender, shoi'ter than the head and thorax; basal 

 joint cylindi-ic, its length double the breadth, second oval, distinctly 

 longer tlian I)road, the next small and narrowed towai'ds the base; joints 

 4-."^ small and bead-like, the 5th and 7th slightly larger; 9th twice 

 as large as its predecessor but not as broad as the transverse lOth, the 

 terminal largest, subovate. 



Underside chestnnt-red, finely pubescent. Head with a large fovea 

 behind the middle and finely carinate in front. Prosternum carinate 

 along the middle. .Metasternum elongate, with a large rotundate im- 

 pression behind the middle. Basal ventral segment hidden by tlie 

 femora, segments 2-5 subecjual, the 2nd transversely elevated at each 

 side of the middle, 5th widely emarginate, 6th large, wndely impressed 

 at the base, with an indistinct median, conical operculum. Intermediate 

 ti-ochanters with very prominent spines, those of the posterior much less 

 distinct. 



The finely sculptured shining surface prevents its being placed in the 

 same section as the typical exponents of the genus, such as 7j . ohitcurus, 

 2-1:78, and 2477. It can be at once separated from Z. raffrayi, .'5.'582, by 

 the absence of the thick longitundinal carina at the base of the meta- 

 sternum, which, moreover, has the operculum of the last ventral segment 

 distinctly convex. .3.38.'^ is distinguished by its small, closely punctate 

 head, and .3384 by its broad r/V/c///;//.s'-like body.

 small lateral foveae. Elvtra elongate, nearlv double the length atid
