AMERICAN COLEOPTERA. 301 



really belongs to the genus. I feel unwilling with the material 

 before me to separate it, in fact there is no character in which 

 it differs from Ejmraea, although I suspect that the tarsi are not 

 dilated, there is however bat one tarsal joint remaining in the 

 specimen in my cabinet, although I have seen two others equally 

 mutilated. It resembles a miniature Emhaphion with the elytra 

 conjointly emarginate. 



Collected in Colorado, by H. K. Morrison. 



Group III. 



This -roup contains but one small species in which the posterior 

 tibiae of "the male are slender at the basal two-fifths, while the apical 

 portion is rather suddenly twice as wide as it. (PI. Ill, fig- 20). 



E luteola Erichs.-Oval, slightly oblong, fulvo-testaceous, moderately 

 shining, sparsely pubescent. Head sparsely punctulate. Antenna pale, club 

 darker formed as in ..onoga,.a. Thorax nearly twice as w.de as long, nar- 

 rowed in ront, apex feebly emarginate, base truncate, sides feebly arcuate 

 h^d angles rectangular, margin very narrowly reflexed, surface -t densely 

 punctate Elytra very little longer than wide, slightly narrowed poster.orly, 

 apex truncate' margin very narrowly reflexed, disc moderately convex punc- 

 tured like the thorax. Body beneath rather finely and sparsely punctulate. 

 Length .08— .09 inch; 2— 2.25 mm. , 



The middle tibiae are simple in the two sexes. The posterior tibiae 

 of the male are slightly arcuate, the basal half slender, the apical half 

 rather suddenly broader although not much dilated. Mr. Crotch s 

 reference of this species to Dadopora Thoms., associating it with 

 decemqiittata is entirely erroneous. , , p , 



This species is one of the smallest in our fauna, and the females 

 can be distinguished from those of lahllis by the sparser punctuation 

 and more narrowly reflexed margin, they otherwise greatly resemble 



that species. . ,. 



In distribution this species appears to be becoming cosmopolitan. 

 Originally occurring in our Gulf States and Cuba, it has spread to 

 Europe, (Reiche), and Ceylon, (Murray). 



Mr Reitter has placed this species in a genus of his own creation, 

 Haptoncura, the characters of which seem to me entirely too feeb.e 



to adopt. _ . , .1 p 



In addition to the foregoing species, Mr. Reitter describes from 



our fauna : 



E. macroplitlialma Reitter.-Elongata, subdepressa, subnitida, levis- 

 sime punctulata, tenu.ter puberula, testaceo-ferruginea, ant.ce attenuata ; ocul, 



Indibus, nigr s, thorace transverso, antice et ap.ce subtruncato later.bus 

 feTssime rotuudltis, antice valde angustatis, vix margmato-reflex.s; elytr.s
