Genus ANSA. 



Corpus aspere punctatum. Caput subrostriforme, antice rotundatum, 

 thoraci squilougum ; lobi sequilongi. Rostrum segmentum ventrale 3um 

 paullo superans. Antennae setulosae, sat graciles; articulus lus faciem non 

 attingeus; 2us brevissimus; 4us 3o valde brevior; 5us 4o longior. Thorax 

 lateribus anticis serratis, angulis posticis acutis productis. Scutellum 

 longiusculum, apice latum rotundatum. Venter basi subsulcatus. Pedes 

 graciles; tarsi triarticulati. Membrana venis longitudinalibus exparle 

 furcatis et conjuuetis. 



Body elongate-elliptical, roughly punctured. Head porrect, subrostri- 

 form, rounded in front, as long as the thorax, narrower including the eyes 

 than half its breadth ; lobes of equal length. Eyes prominent. Rostrum 

 extending a little beyond the hind border of the third abdominal segment. 

 Antennae setulose, rather slender; first joint not extending to the front of 

 the head; second about one-sixth of the length of the third; fourth very 

 much shorter than the third ; fifth rather longer than the fourth. Thorax 

 about twice as broad as long; hind angles acute, prominent; sides serrated 

 in front. Scutellum much more than half the length of the abdomen, 

 broad and rouuded at the tip. Abdomen beneath slightly furrowed towards 

 the base. Legs slender; tarsi three-jointed. Fore wings not extending 

 beyond the abdomen; membrane with longitudinal veins, a few of which 

 are forked and connected in the disk. 



The structure of the head and the seriated sides of the thorax 

 distinguish it from Agccus, and it differs from Ccenomorpha in the shortness 

 of the second joint of the antennae, in the less attenuated scutellum, and in 

 the narrower abdomen.
