than second, fourth segment pale castaneous, subequal to second. Posterior 

 lobe of pronotum sometimes a little paler, more coarsely and sparsely punctate 

 than anterior lobe. Scutellum sparsely punctate and apically carinate. Clavus 

 with three regular rows of punctures. Commissure about one-half the length 

 of the scutellum. Corium unicolorous, sparsely punctate, costal margin very 

 lightly expanded and convexly rounded. Membrane decolorous, reaching apex 

 of abdomen. Length 3 mm. 



Type — ^ ? U. S. N. ^T. labelled Tex.; Paratypes — 2 specimens 

 from Texas and one labelled Lavaca Co., Tex (U. S. N. M.). The 

 genital segment is so firmly glued to the point that it is impossible to 

 determine the sex of the type. This species resembles a very small 

 pale Pcrigcncs. 



Genus Esuris Stal. 

 Stal placed this genus, based upon his E. tcrgina from Brazil, in 

 the tribe Leth^aria. I have carefully examined numerous specimens 

 of my E. castanea from Arizona and two specimens of the new species 

 described below and can find but two widely separated glandular 

 opaque spots on the side of the fourth ventral segment, placed in 

 reference to each other exactly as they are in the other genera of the 

 Myodochini. I would therefore transfer this genus not only because 

 of the position of the opaque spots but furthermore because the 

 obtuse, terete character of the lateral margins of the pronotum 

 would serve to place this genus among its natural relatives close to 

 Ptochiomera in the tribe Myodochini. Furthermore in diagnosting 

 the characters of this genus Stal depended upon the brachypterous 

 character of the hemielytra and the fact that the clavus was connate 

 with the corium. These characters will not serve except for differ- 

 entiating the brachypterous forms as I have recently discovered in 

 my collection two macropterous females of E. castanea in which the 

 clavus is distinct from the corium and the membrane fully developed. 

 I have recently seen a specimen of E. castanea Barb, from Ft. Collins,. 

 Colorado, in the collection of Dr. E. D. Ball. 



Esuris fulgidus new species. 



Dark brown or piceous, very shining; second and third segments of 

 antenna;, rostrum, apices of femur, tibia and tarsus ochraceous. Head tri- 

 angular, a little wider than long, across eyes as wide as across anterior sub- 

 margin of pronotum, finely punctate. Antennse finely pilose, basal segment 

 piceous, short, scarcely exceeding tylus, shorter than basal segment of rostrum,
