Goleopterological Notices, VII. 53T 



Michigan (Ann Arbor) and Pennsylvania. The description 

 given above is drawn from the original type of punctatus. A 

 large series from Pennsylvania agrees well, and in this series I 

 can only distinguish the male from the female by the broader and 

 somewhat larger head and very slightly stouter form ; both sexes 

 seem to have the sixth segment very large and longer than the 

 preceding four, and there is generally a small apical and more 

 densely pubescent erosion. The anterior tarsi are rapidly stouter 

 toward base and densely papillose beneath. 



If this species is correctly identified, I cannot understand the 

 statement twice made in the original description — " coleopteris 

 . . . confertim punctulatis," and " coleoptera , . . 'subtiliter 

 punctata " — when the elytra are unusually strongly punctured ; it 

 was described by Schaum from a Carolina specimen sent by Zim- 

 mermann. Motschulsky states (Etudes Ent., 5, 1856, p. 11) that 

 the S. zimmermanni of Schaum, lives with ants under the bark of 

 old trees, where he took it near Atlanta, Georgia. 



2. A. retrusa n. sp. — Moderately stout and rather ventricose, polished, 

 the head impunctate ; pronotum excessively finely, sparsely punctulate and 

 not more distinctly so toward base, the elytra sparsely and very minutely 

 punctate ; pubescence rather sparse, nearly even, short and subdecumbent. 

 Head quite distinctly wider than long behind the antennae, with the sides 

 perfectly parallel, evenly and broadly arcuate throughout, rounding subtrans- 

 versely for a short distance to the neck, which is about % as wide as the head; 

 eyes small and not prominent ; surface feebly and evenly convex, the scanty 

 hairs arranged subtransversely ; antennal prominences not distinct, the frontal 

 lobe short and broadly rounded. Antennas barely }4 ^-s long as the body, 

 slender, the club rather rapidly incrassate ; basal joint narrowed at base, fully 

 twice as long as wide, distinctly thicker than the second but only about 3^ 

 longer, the second very slightly thicker and much longer than the third, feebly 

 obconic ; second nearly once, third and fourth equal, %, fifth %, sixth 3^, 

 longer than wide ; six to eight oblique at apex ; seventh and eighth subequal, 

 scarcely wider, much shorter than wide ; ninth rather small, barely as long as 

 the two preceding and only }4 wider, obconic, slightly elongate ; tenth much 

 larger, longer than the ninth and ^4 wider, obtrapezoidal with rounded sides, 

 about as long as wide; eleventh only just visibly thicker, oval, gradually 

 pointed, much shorter than the two preceding. Prothorax rather longer than 

 wide, more than % wider than the head, widest and evenly rounded laterally 

 at apical third, the sides thence oblique and straight to the base ; surface 

 strongly convex, very feebly and transversely impressed near the basal margin, 

 with two minute and very approximate subbasal fovese near each side. Elytra 

 subrhomboidal, strongly convex, scarcely more than J^" longer than wide, a 

 little more than twice as long as the prothorax and % wider, widest and 

 strongly rounded just before the middle ; sides strongly convergent and nearly
