CERAMBYCIDiE. 



Pnrawh'a Sai/i, qnadn'collis, con/ormis, dentatn and mimifa, Thoin* 

 son, are all merely slight variations of hniunca Fab. 



P. po/ita Say., occurs also in Mexico, wheace it has been described 

 by Chevrolat under the name cyUmlricn. 



It may be well to mention here that two forms occur in Parandra, 

 first, the long, slender, shining and depressed form, and secondly, the 

 shorter, more robust, less shining and more convex. The former with 

 distinct onychium and paronychia, and the latter with both so retracted 

 as to be almost invisible. ]My attention was directed to the apparent 

 absence of onychium in our common species by Mr. II. W. Bates, and 

 subsequent examination has shown that the form of body is also an 

 indication of the development of the onychium in any of the species. 



Pilcma Lee, is thought by Mr. H. W. Bates, to be identical with 

 Callimus Muls. The form of the one certainly resembles very greatly 

 the other, but having no specimen of Callimus with which to compare 

 Pilcmci, the latter name must be allowed to stand, inasmuch as the 

 best three European descriptions vary so greatly as to leave the matter 

 in great uncertainty. 



Callimus chalybsens Lee, is however not a Callimus. 



(Jtytus nitidtts Horn, is omitted from the Check List on suspicion 

 that it might be C. magicus. This however is not the case, nitidus is 

 a Xylotrcchus and magicus a Neoclytus. I was moreover unable to find 

 any species in Europe at all resembling it. The name must therefore 

 be restored to the List. 



Plngi/thmysua pulveridentus Motsch., is distinct from any species I 

 have seen and appears- to be a Neoclytusj and if so the generic name 

 of Motschulsky has priority. 



Amphidesmus xanthomelas Guerin. Specimens in the Jardin des 

 Plantes from Lower California. 



Monohammus minor Lee, is probably identical with carolinensis 

 Oliv., and is doubtfully valid as a species. 



Eutessus anper Lee, is Mev.otetartus antennatus Bates. This species 

 occurs from Lower California to Yucatan. 



PogoHocherus sordidits Lee, is an Eslola Fairm. 



AMFIIIOXYCIIA, Lee. 

 The first appearance of this name is in the catalogue of the collec- 

 tion of Dejean. Ilaldeman quotes the name from that author without 

 however giving any description, (Trans. Am. Phil, Soe, 1847, p. 57), 

 redescribing A. marginata Fab The name next appears in " An 

 attempt to classify the Lougicoru Coleoptera of the part of America
