122 PHYTOPHAGA. 



and a half times as broad as long, surface opaque, perfectly iinpunctate ; elytra minutely geminately 

 punctate-striate, the punctuation entirely disappearing towards the apex, at which place there are faintly 

 impressed lines ; legs fulvous. 



Hah. Mexico, Oaxaca (Boucard, coll. SalU). 



Three specimens of this very distinct species are before me. Although allied to 

 N. cribellata, it is at once distinguished from that species by its totally impunctate 

 head and thorax, its long antennae, and its fulvous legs. 



SPINTHEROPHYTA. 



Spintherophyta, Dejean, Cat. 3rd ed. p. 434 ; Lefevre, Rev. et Mag. de Zool. 1875, p. 104. 



This genus was founded by Dejean (without description) upon certain species now 

 classified under the genus Chrysodina. M. Lefevre applied Dejean's name to two 

 Mexican insects having the general appearance of the members of the last-named 

 genus. The thorax of these insects, however, is much more transverse and of equal 

 width to the elytra ; the epistome is deeply emarginate, and the prosternum of different 

 shape. These insects are not altogether strangers to other parts of America, several 

 undescribed species from the Amazons region being contained in collections. 



1. Spintherophyta lesueuri. 



Spintherophyta lesueuri, Lefev. Rev. et Mag. de Zool. 1875, p. 105 \ 



Hob. Mexico \ Toxpam, Cordova (Salle), Jalapa (Hoge) ; Guatemala, San Joaquin, 

 Balheu (Champion). 



The male of this species may be known by the greater development of the mandibles 

 and the dilatation of the anterior tarsi. The elytra are closely and not very strongly 

 punctate-striate, and there is no trace of a transverse basal depression. 



2. Spintherophyta cephalotes. (Tab. VII. figg. 1, 2.) 



Spintherophyta cephalotes, ,Lefev. Ann. Soc. Ent. de France, 1876, p. 115. 



Hab. Mexico, Cordova (Salle). 



From the preceding species the present one is separated by the fulvous antennae and 

 legs, as well as by the much greater development of the mandibles in the male ; the 

 puncturing of the upper parts does not differ much from that of S. lesueuri. The types 

 from M. Salle's collection are figured here, male and female.

narrowed and deflexed in front ; elytra rugose punctate-striate.
