quite isolated otherwise. The typical ruhicunda is rather stout, with 

 subimpunctate polished integuments, elytra distinctly shorter than 

 wide, abdominal carinas rather long, divergent and separated by 

 between one-fifth and one-sixth of the entire width, the pubescence 

 long, bristling and coarse, and the male sexual characters feeble, the 

 last ventral flattened and the last dorsal with a very small apical 

 sinuation, two or three times as wide as deep, with its lateral limits 

 not abruptly defined. In gracilicornis the body is equally stout 

 and the carinas similar, but the vestiture is a little shorter and 

 coarser, and the last dorsal has at apex a small semi-circular nick, 

 abruptly limited by acute angles, the last ventral just visibly im- 

 pressed. Gracilis is narrower and still more hirsute than rubicmida, 

 though similarly carinate, and has the last ventral deeply impressed, 

 the last dorsal being broadly sinuate at apex, the sinuation about 

 twice as wide as in ruhicunda or gracilicornis but nearly similar 

 in shape to that of the former. Atlantica also has the vestiture 

 long, erect and hirsute, but the abdominal carinas are much closer, 

 nearly as in diver gens. 



On the other hand divergens, facilis, cribricoUis, congener, 

 furtiva and inepta, have the pubescence decidedly shorter and 

 more recumbent, and the abdominal carinas generally less distant 

 though in diff"erent degrees; in inepta they are relatively a little 

 more distant than in ruhicunda, this species as well as congener 

 being distinguished also by its minute size. In congener, furtiva 

 and cribricoUis — if I have correctly identified this species — the 

 carinas are a little less distant than in ruhicunda but more distant 

 than in facilis and divergens, where they are separated at base by 

 a distance not greater than that of the sutural strias at the middle 

 of the elytra. CribricoUis has an unusually long prothorax. 



Divergens was recently redescribed by Brendel under the name 

 canadensis, specimens sent to me by the author agreeing completely 

 with the types in the LeConle cabinet ; the pronotum in these types 

 is sparsely and coarsel}^ but feebly punctate, more distinctly so ante- 

 riorly and not impunctate as stated in the original description. 

 The species is easily recognizable by its short transverse and roughly 

 scabro-punctate elytra. Facilis is a widely different species with 

 longer, subimpunctate elytra and still more minute appressed pu- 

 bescence ; it differs also in antennal structure and male sexual 

 characters, and was possibly described by Brendel under the name 

 divergens Lee.
