NO. 9 GENUS CHLAENOBIA BLANCHARD CHAPIN II 



Antennal club a little shorter than second to seventh segments com- 

 bined. Sixth sternite with its free margin rather strongly produced 

 in a broad lobe. Pygidium transverse, median line sharply impressed, 

 with a conical boss on either side of median line at middle of length, 

 apical third shallowly excavate, apical margin subtransverse and 

 sharply reflexed. Anterior tibia tridentate. 



Length. — 13.5 to 15 mm. 



Type locality. — Teapa, Mexico (latipes) ; Tomatlan and Tuxtla, 

 Mexico (hicallosa). 



Types. — In the British Museum. 



Material examined. — Two males from Cordoba, determined as this 

 species by Arrow but previously determined by Bates as aegrota; one 

 female, apparently a paratype of hicallosa, from Tomatlan; seven 

 males and nine females from Cordoba, V. C, Mex., May 12-June 9, 

 Fred. Knab; one male and one female from Chiapas, Mexico, in 

 collection of L. W. Saylor. 



Two males and a female were taken by Knab on May 12 and 

 again on May 16. It seems unlikely that these sexes are not of the 

 same species. The males compare favorably with the two specimens 

 determined by Arrow, and one of the females has been compared by 

 Arrow with the type of hicallosa. The original description of the 

 female of latipes is not materially different from that of hicallosa. 



CHLAENOBIA PANAMANA, n. sp. 



Head densely and moderately coarsely punctured on frons, vertex 

 and region adjacent to clypeofrontal suture, which is deeply impressed 

 and strongly biarcuate, very sparsely punctured. Frons evenly and 

 slightly convex. Clypeus shallowly concave, its outer portion not 

 sharply reflexed, margin distinctly indented at middle. Antenna ten- 

 segmented. Pronotum transverse, side margin obtusely angulate just 

 before the middle, lateral margin strongly sinuate just before the 

 posterior angle as viewed from the side, viewed from above anterior 

 angle subacute, posterior angle acute and slightly produced ; punctures 

 coarse, densely placed on disk, more sparsely so on flanks. Scutellum 

 equilateral, rather sparsely punctured. Elytra with sutural margins 

 narrowly tumid, each with two feebly indicated discal costae, of 

 which the first (from suture) is more developed than the second; 

 punctures as coarse and a little more densely placed than on disk 

 of pronotum, epipleura very narrow, not well defined beyond middle 

 of the length. Metasternum moderately coarsely and very sparsely
