250 Mr. J. O. Westwood on Evania and 



India as the locality of this species, from the information of Dr. 

 Fothergill. This, however, is incorrect, it and all the other species 

 of the genus being inhabitants of America. 



The following is a description of the male, from specimens in 

 the collection of the British Museum, and which is represented in 

 PI. XIV. fig. 1. 



Black, shining ; four anterior tibiae and tarsi brown ; two basal 

 joints of posterior tarsi black, the remainder dirty white; the 

 wings having the costa and apex brown, the costa being the darkest 

 part. 



Length 7 lines, expansion of wing 10| lines. 



Specimens of the males are also preserved in the Royal Museum 

 of Berlin, where, upon the authority of Dr. Klug, they are ticketed 

 Pel. clavator, Latr., of which the following is the description : — 



" Pelec'mus niger, antennarum articulo lOmo tarsorumque 

 duorum posticorum articulis intermediis albidis, abdomine clavato." 

 — Latr. in Diet. d'Hist. Nat. edit. 2. 



As, however, the habitat given is Brazil, it is perhaps the male 

 of another species. The specific name is at all events inappro- 

 priate, being applicable to the males of all the species both of this 

 and the following genus. 



I have received many specimens of Pelec'mus poUturator from 

 North America, and Dr. Harris has introduced it into his cata- 

 logue of the insects of Massachusets, as well as Pel. clavator. It 

 is also figured by Say in his American Entomology, vol. i. pi. 15, 

 who states that it is not uncommon in various parts of the United 

 States. 



Since this memoir was prepared, the Baron de Romand has 

 published a note on this genus in Guerin's Magasin de Zoologie, 

 1840, Ins. pi. 48 and 49, figuring the males of two supposed 

 species under the names of P. polycerator and polyturator (not 

 perceiving their identity and relying on the different spelling of 

 the name, as I had written the latter name on the sketch of the 

 male which I gave him when in London). 



Dr. Klug, in his description of the species of this genus in the 

 Berlin collection, describes three varieties of P.jjoliturator varying 

 in the punctation of the scutellum and metathorax, from North 

 America, Mexico, Columbia, and Brazil, 



In the " Delectus Animalium," &c., of Drs. Spix and Von 

 Martius, Dr. Perty has described three species as belonging to 

 this genus, the third of which, however, is referable to Mono- 

 machus. The following is the description of the two other 

 species : —
