Redescribed from one male collected at Boulder. Colorado, by Proi. T. D. 

 A. Cockerell. Food- plant: Capsicum aiiiiuum (pepper). 



The single male specimen sent me by Prof. Cockerell was imperfectly colored 

 as compared with the description by Sulc. His characterization of color 

 and of the genitalia of both sexes was used in the above description since 

 these characters were not readily available in my specimen. The striking 

 similarity to P. occUata is apparent. The two species niav be distinguished by 

 the following characters : 



Paratrioza occUata : Facial cones nearly pnrrect and horizontal : antenn;e 

 inserted on frons sublaterad ; vertex with a white macula in center ; thorax ; 

 usually distinctly striped. Anal valve of male long and rather narrow, with 

 a small rounded epiphysis posteriorly ; vertical a.xis longer than horizontal axis. 



Paratrio:;a cockcrclli: Facial cones not porrect, projecting outwardly, hori- 

 zontal ; antennse inserted more nearly in front ; macula in center of vertex 

 lirown ; thorax not distinctly striped. .Anal valve of male relatively shorter; 

 posterior lobe or epiphysis large, triangular, long at base, subacute at ape.x ; 

 vertical axis shorter than horizontal axis. 



Paratrioza maculipennis (Crawf.)

The facial cones are somewhat larger and more prominent in this species, 

 but are manifestly of the same type. The male genitalia are more accurately 

 represented in the figure herewith shown than in the location cited above. 



Neotrioza n. gen. 



Head with eyes distinctly broader than thorax. Facial cones quite long, 

 very slender and acute, closely appressed and not in the least divergent. 

 Vertex raised plate-like. Antennae inserted in front below vertex. Thorax 

 very slender and narrow. Pronotuni short, depressed below head and 

 dorsulum. 



Type of genus : Ncotrio::.a itmuaciilata Crawf.
