 SYNOPSES OF CERAMBYCIDiE.

(Continued tVoin p. i6o, vol. vi.) 



LEPTURA Serville. 

 The species of Lcptura were arranged in synoptic form by Dr. 

 LeConte in 1873. Since that time a few changes have been noted 

 by Dr. Horn in various pubUcations, and the result appears in the. 

 '' Check List" of Mr. Henshaw. A few more remain to be noted 

 as lollows: 



cyaiiella Lee. is undescribed, and = chalybaea Hald. 



zebra Ollv. should be nitens Forst, on account of priority. 



quadrata Lee. is a form of instabilis I laid 



canadensis Fab. should read canadensis OH v. 



ebena is a name proposed for a totally black form of canadensis. 



crassisornis Lee. is the female of crassipes Lee. 



vittata Germ, should read vittata Oliv. 



spuria Lee. = Acmseops militaris Lee. fide Dr. Horn. 



vexatrix Mann., formerly placed as a synonym of sexmacillata Linn., 

 appears to be a distinct species. 



For the last two corrections I am indebted to Dr. Horn as well 

 as for many minor suggestions not specially acknowledged in the 

 notes which follow the synopsis, and in preparing the lists of locali- 

 ties for the various species I have enjoyed the use of Dr. Horn's 

 collection and the valuable assistance of Mr. Henshaw. 



The following synopsis closely follows that of Dr. LeConte and 

 incorporates all the changes that I have been able to discover. The 

 descriptions of varieties in coloring are stated in the notes at the end.
