I have found tliree specimens of an insect which puzzles me 

 a o-ood deal. Accordino; to Latreille, in the Resjne Animal, it 

 would undoubtedly be a S'erropalpus, as the penultimate joint 

 of the tarsi is bifid in the first and second pair of legs, the 

 maxillary palpi serrated, and the last joint nearly "m forme de 

 haehc allongeey But Leach, in the eighth volume of the 

 Edinburgh Encyclopasdia, says the body is " almost cylindrical 

 and very long." That does not agree with my insect, which 

 resembles so much a Cistela I have, that at first I compared 

 them to ascertain whether they were not of the same species. 

 The insect is blackish or piceous above, and hairy; antennae, 

 palpi, feet and entire under surface, ferruginous. The elytra 

 have about nine punctured striae. The head and thorax are 

 punctured, and the thorax has a slightly impressed indentation 

 on each side at the Ijase. 



Leach's remark does not seem sufficient to make me call this 

 insect anything but Serropalpus^ but I will receive your remarks 

 upon it with great pleasure. 



I have an insect now marked Stcnostoma from Massachusetts, 

 » first marked Tclepliorus by an unaccountable mistake, for it is 

 unquestionably heteromerous. It may be an (Edemera, but the 

 elongation of the mouth made me prefer placing it in Stcnostoma. 

 The last joint of the maxillary palpi is neither quite cylindrical 

 nor securiform. The insect is pale yellow, the thorax deeper 

 yellow, dark beneath, and the tip of the elytra is blackish. 

 Can you inform me about this insect ? It undoubtedly resem- 

 bles Teh'pliorus very much in all respects, except the subcylin- 

 drical thorax. The length is not quite | •} inch. 



You may recollect having seen a little Clems? which I 

 collected at N. Hampton, with scarlet elytra, now marked 238. 

 [238 Hentz's mss. Catal. = OpUus ? coeeineus Harr. mss.] 

 The labial })alpi seem to be securiform, but are much sm.aller 

 than usual in that family. At first it may appear tetramerous, 

 but the first joint can be easily discovered with a strong magni- 

 fier. The joints of the hand are w^ider, as in St ajyJii/l inns, and
