Platyxin.e 75 



paler, rather less opaque toward the sides than in punctiformis; 

 head narrower, evidently elongate, only three-fifths as wide as the 

 prothorax, similarly with rather large but only moderately prominent 

 eyes; palpi black, paler at tip; antennae fuscous, paler basally, 

 very slender, fully half as long as the body; prothorax nearly as in 

 punctiformis, except that the foveee are attended by an irregular 

 impression, which is sometimes traceable almost to the middle; 

 elytra shorter and relatively still more inflated, a little less than 

 one-half longer than wide, the siinilarly rather coarse deep striae 

 sometimes more obviously punctate laterally than in the preceding; 

 intervals moderately convex; met-episterna somewhat less elongate, 

 generally a little less than twice as long as wide; anterior male tarsi 

 long and extremely feebly dilated. Length (cf 9 ) 6.2-7.8 mm.; 

 width 2.3-3.15 mm. North Carolina (Southern Pines) and Ala- 

 bama (Mobile). Thirteen specimens rigidula n. sp. 



A — Distinctly stouter than rigidula, more ventricose and with re- 

 latively smaller prothorax; general characters almost similar, 

 the pronotal fovese small, punctiform, discal and isolated; elytral 

 striae coarse, deep, grooved, slightly impressed, moderately punc- 

 tate, the lateral striae finer and more distinctly punctate; under 

 surface opaque laterally. Length (9) 7.7 mm.; width 3.0 mm. 



Virginia (Norfolk) semipunctata n. subsp. 



B — General characters of color, lustre and sculpture as in rigidula, 

 but much more abbreviated, the prothorax similar in form and in 

 the subdual nature of the foveae, but relatively larger in size; 

 elytra much shorter, scarcely a third longer than wide, more 

 rapidly obtuse behind,' one-half wider than the prothorax, the 

 striae deep, feebly punctulate, the intervals strongly convex, the 

 three punctures of the third similarly subaxial along the interval. 

 Length (9 ) 7.2 mm.; width 2.8 mm. North Carolina (Southern 



Pines), — Manee putata n. subsp. 



Body almost as large as in rufipes and more ventricose, the hind body 

 broadly oval and relatively shorter, polished black, the legs clear 

 rufous; under surface only feebly opaculate laterally; head rather 

 elongate, much narrower than the prothorax, with large and moder- 

 ately convex eyes; antennae slender, slightly over half as long as the 

 body, piceo-testaceous, clearer basally; prothorax nearly as in 

 rigidula in form and proportion, the foveal impression irregular 

 and by some reflections formed of two small punctiform foveae; 

 elytra one-half longer than wide, fully three-fourths wider than the 

 prothorax, the parallel sides much more arcuate than in rufipes, 

 only a little more rounded basally, the hind wings apparently not 

 developed; striae grooved, with the punctures small, feeble and 

 everywhere rather indistinct; intervals only feebly convex. Length 

 (9) 8.2 mm.; width 3.2 mm. Alabama ^lobile), — Loding. 



ventricula n. sp. 



5 — -Strial punctures smaller, rather close-set and crenulating the intervals 



barely at all, though distinct in all the striae from the sides to the 



suture, becoming smaller in the very fine lateral striae. Body 



elongate, only moderately convex, polished black above, the under
