78 Psyche [August 



brachypterous forms the membrane is only short- 

 ened, the clavus always deflected to the cerium. 

 Species very shining. (Type — Rhyparozhnmus 



plenus Dist.) Kolenetrus Barb. 



JJ. Scutellum subequilateral, posteriorly not dis- 

 tinctly carinate. Pronotum either not pilose and 

 finely punctate in front, in which case it is not 

 strongly constricted to form two lobes or the pro- 

 notum very pilose and obsoletely punctate in 

 front and then strongly and obtusely constricted 

 to form two lobes. Posterior tarsus with basal 

 segment decidedly longer than second and third 

 together. Species not at all or faintly shining. 

 L. Antennse and dorsal parts very pilose. Pro- 

 notum longer than wide, strongly contracted 

 back of the middle to form two lobes; the' anter- 

 ior lobe obsoletely and sparsely punctate. First 

 segment of antenna longer exceeding apex of 

 tylus by nearly one-half its length. Costal 

 margin of corium gently con vexed. Fore- 

 femora provided with two or three minute pre- 

 apical teeth and long setae throughout. Clavus 

 distinct and deflected to the corium. Membrane 

 reaching the end of abdomen. Only macrop- 

 terous forms known to me. (Type — Valonetus 



pilosus Barb.) Valonetus Barb. 



LL. Antennae and dorsal parts not at all or very 

 sparsely pilose. Pronotum lightly transverse 

 or quadrate, finely and distinctly punctate, 

 anterior disk sometimes impunctate, not strongly 

 constricted to form two lobes. First segment of 

 antenna short barely exceeding tylus. Fore 

 femora armed with two or three minute teeth 

 in the middle, tipped with long setae. In 

 brachypterous forms clavus connate with the 

 corium, the membrane wanting and pronotum 

 more quadrate. (Esuris tergina Stal and cas- 

 tanea Barb.) Esuris Stal.
