COLEOPTEKA. 177 



tip; third joint of th(^ antennae very slightly longer than the fonrth, clnb 

 sliglitly longer than the remainder ; there are near the eye on the upper 

 surface several short setae which sometimes extend iu-a curved line across 

 the head along the clypeal suture, and there are also a few scattered setae 

 on the disk of the clypeus. Prothorax from above about twice as wide as 

 long; sides very slightly convergent from base to apex, and rather evenly 

 and distinctly arcuate ; apex about two-thirds as long as tlie base, trans- 

 versely and strongly eraarginate, angles acute ; base broadly arcuate, feebly 

 sinuate at each side of the middle, angles slightly obtuse and rather strongly 

 rounded ; disk glabrous, moderately convex, finely and rather feebly punc- 

 tate ; punctures distant by from two to three times their own widths ; lateral 

 margins very narrowly reflexed and having a row of a few long erect setae. 

 Scutellum very Hat, much longer than wide, sparsely punctate. Elytra 

 across the humeri slightly wider than the pronotum ; sides parallel and 

 nearly straight ; together very abruptly and obtusely rounded behind ; disk 

 two-thirds longer than wide and three times as long as the pronotum, convex, 

 glabl'ous ; longitudinal costae fine, not punctate, rather feeble, intervals 

 narrower, feebly impressed, finely and irregularly punctate ; epipleurae 

 having a row of rather closely placed erect setae. Under surface opaque, 

 finely and feebly punctate, nearly glabrous except on the coxae and last 

 ventral segment where there is a rather long fine and somewhat conspicuous 

 pubescence. Legs slender, long slender posterior tibial spurs but sliglitly 

 unequal in length ; posterior tarsi very long and slender, each joint having 

 throughout its length beneath two. acute unequal carinae, the larger one 

 being finely granulose ; first joint slightly longer than the second; claws 

 rather long, deeply cleft at tip, terminal portion strongly bent, inner tooth 

 robust, having the tip acute and very oblique. Length 8.0-9.0 mm. ; width 

 4.3-4.7 mm.

This species eiin be distinguished from sericea by its smaller size, 

 much paler color, and very large prominent eyes, and also by the 

 shape of the posterior tarsal claw which is slightly shorter, more 

 robust, and with the a[)ical portion finer and prolonged further 

 beyond the inner in sericea. The surface when viewed perpen- 

 dicuhiHy is not iridescent, but a slight amount may be observed 

 when it is viewed very obliquely. The large eyes referred to above 

 is apparently not a sexual character, as the sexes may be very readily 

 separated by the longer or shorter antennal club, and there is then 

 seen to be no very markeil difference in the size of the eye. It may 

 prove a constant character for grouping aptirt some of the species in 

 this difficult genus, as there is another species represented in my 

 cabinet allied to tristis but having much larger eyes. 



S. porcilla n. sp. — About twice as long as wide, sub-<;ylindrical, dark 

 reddish-brown, legs and under surface sliglitly paler ; shining throughout, 

 not iridescent ; glabrous above. Head but slightly wider than long ; occiput 

 rather sparsely finely and irregularly punctate ; clypeus very densely and
