206 NEW SPECIES MELYR1DAE, CHRYSOMELIDAE AND TENEBRIONIDAE 



mesosternum is different and the eleventh joint of the antennae is oval as 

 in Centrioptera while in laevis it is short and truncate. The form is 

 similar in nunenmacheri and convexus, but the latter is larger. 



Schizillus lomae, new species. Form oblong-oval, moderately broad 

 and rather robust, elytra slightly flattened on the disk. Color black, 

 feebly shining, somewhat alutaceous anteriorly. 



Head moderately broad, feebly and broadly impressed between the 

 antennae, epistoma very feebly convex at middle ; surface smooth, 

 sparsely punctate ; punctures small and not strong, densely placed along 

 the fronto-epistomal margin which is hemi-hexagonal. Antennae slender, 

 joints of equal width, third joint a little longer than the fourth, the latter 

 a little longer than the fifth ; fifth, sixth and seventh nearly subequal, ninth 

 and tenth somewhat compressed, tenth triangulo-oval, eleventh oval, about 

 as long as wide, pointed at middle of tip. 



Pronotum about a third wider than long, transverse ; apex deeply 

 emarginate, bottom of the emargination almost transverse in the middle 

 two-fourths, thence oblique to the apical angles, which are subacute, 

 broad and anteriorly prominent, marginal bead present within the angles ; 

 sides strongly, broadly and evenly arcuate in the anterior four-fifths, thence 

 sinuate and parallel to the basal angles, marginal bead rather coarse and 

 somewhat reflexed ; base broadly and arcuately emarginate, bead coarse ; 

 basal angles less than a right angle, blunt and somewhat prominent pos- 

 teriorly, marginal bead strong about the angles ; surface smooth and 

 obsoletely sculptured, moderately strongly convex in the central area, 

 especially anteriorly, less so posteriorly, rather broadly impressed laterally, 

 with a gutter posteriorly which is continuous with the short ante-basal 

 transverse impression, the latter moderately strong; slightly impressed 

 within the apical angles and strongly impressed within the basal angles. 



Propleura smooth, with a submarginal line of short rugulae. 



Elytra broadly oval, about a fourth longer than wide, dorsum rather 

 feebly convex, strongly but not broadly rounded at the sides, apical 

 declivity almost vertical, apical lobe short and broadly rounded ; humeri 

 obsolete, base equal to the pronotal base ; scutellum very small and tri- 

 angular; surface sculptured with rather close series of punctures which 

 are simple in the central area of the disk, becoming muricate and then 

 muricato-rugose on the lateral and apical declivities ; strial punctures more 

 closely placed and slightly larger, the interstitial series a little smaller and 

 more widely spaced. 



Epipleura rather wide and obsoletely sculptured. 



Parapleura. Mesosternal pieces rather densely punctured ; meta- 

 sternal pieces sparsely punctate, punctures a little larger, surface smooth.
