ORTALnXffi SYSTEMATIC DISTRIBUTION. 55 



Hairs on the body of the usual length ; the middle of the thoracic 

 dorsuin bristly on its hind portion only. 



The rounded third antenual joint short, the second of the saiHe- 

 leugth with it. 



Both crossveins not more approximate than usual ; the first 

 longitudinal vein bristly at its end only. 



The genus Ortalis contains species above the average size, 

 some of them rather large ; the abdomen is banded with gray ; 

 the thorax strongly pollinose, in most species with conspicuous 

 black, in some, with gray longitudinal stripes, in a few, without 

 any stripes The wings are more or less spotted. 



Typical species : ruficeps Fab. 



7. SYSTATA Lw. 



Charact. Eyes rather large, elongate oval; front only little projecting. 



The hairs on the body as usual ; the middle of the thoracic 

 dorsum with bristles upon its hind portion only. 



The rounded third antennal joint is short; the second of equal 

 length with it. 



The two crossveins are very closely approximated ; the first longi- 

 tudinal vein bristly at its end only. 



The species of this genus differ from those of Ortalis irr the 

 very close proximity of the crossveins, but agree with them in the 

 remainder of the organization. The picture of the wings con- 

 sists in bands. 



Typical species: rivularis Fab. 



8. LOXODESMA Lw. 



Charact. Eyes large, elongate; front but little projecting; face rather 

 strongly carinate : cheeks narrower than in most other genera. 



Hairs on the body as usual ; thoracic dorsum with bristles upon 

 its hind part only. 



Third joint of the antennae more or less prolonged, rounded at the 

 tip ; the second much shorter. 



Both crossveins very much' approximated ; the first longitudinal 

 vein bristly at its end only. 



The species belonging here remind of the Systatse in the strik- 

 ing proximity of the crossveins, differ however in other respects 

 very much from them, and that in the same way as the species 

 of Pteropsectria differ from Ortalis. The relation of Loxodesma 

 to Pteropseciria, which is by far the most closely allied genus to
