Genus UDANA. 



Corpus dense et subtiliter punctatum, transverse subrugulosum. 

 Caput ihorace sat brevius, antice obtusum et utrinque incisum ; lobi aequi- 

 longi. Rostrum coxas posticas attingens. Antennae gracillimas ; articulus 

 lus caput nou superans. Thorax lateribus rectis, angulis posticis productis 

 glabris rotuudatis subascendentibus. Scutellum sat lougum, apiee 

 rotundatum. Venter non Sulcatus. Pedes graciles ; tibiae sulcata? ; tarsi 

 trial ticulati. Alae anticae subtilissime punctata?, connexivum non 

 obtegentes. 



Body nearly elliptical, thickly and minutely punctured. Head rather 

 shorter than the thorax, obtuse in front; lobes of equal length ; lateral lobes 

 slightly angular near the eye, notched near the fore border. Eyes very 

 prominent. Rostrum extending to the hind coxae. Antennae very slender; 

 first joint not extending beyond the fore border of the head. Thorax trans- 

 versely and very minutely rugulose, nearly twice as broad as long; fore 

 border slightly excavated ; sides straight; hind angles forming two short 

 rounded smooth slightly ascending horns. Scutellum much more than half 

 the length of the abdomen, rather more rugulose than the thorax, rounded 

 at the tip. Abdomen not furrowed beneath. Legs slender; tibiae 

 furrowed; tarsi three-jointed. Fore wings extremely minutely punctured, 

 not covering the sides of the abdomen ; membrane extending to the tip of 

 the abdomen, with six simple longitudinal veins. 



The antennae are mutilated in the specimens described. It may be 

 distinguished from Eclenus by the shorter rostrum, by the shorter basal 

 joint of the antennae, and by the obtuse head with lobes of equal length.
