surface with a sli.2,ht transverse depression before the tip. This depression 

 and an impressed hne from it to the hind margin are marked with pale brown, 

 and six dots are faintly indicated, two just behind the apex, two smaller 

 ones on either side of these and two faint ones behind the hind margin near 

 the eyes, some or all of which may be obsolete. Face broad, obtuse; cheeks 

 very obtusely angled below the eyes; front truncate ovate, at least twice as 

 broad at the ocelli as at the clypeus; the latter widened toward the tip, which 

 is obtusely triangular, and extends a little beyond the loras; lorae broad, to- 

 gether almost circular in form; cheeks barely surpassing the lorae. Face 

 whitish testaceous, tinged with yellowish on the front; sutures of the lorae 

 embrowned. 



Pronotum broadly rounded before, truncate behind; sides very short, the 

 latero-posterior margin reaching almost to the eye; lateral angles rounded. 

 Surface obscurely irrorate or mottled, darker on the disc; beneath whitish. 

 Scutellum about as long as the pronotum; the basal angles and a transverse 

 impressed line dusky or brown; the narrow edge more or less distinctly al- 

 ternated with brown and white. Elytra whitish hyaline, paler toward the 

 apex; broadly clouded with fulvous from near the base to the middle, and 

 from beyond the middle nearly to the apex, leaving a central transverse 

 whitish band; tip of the clavus dark brown; nervures brown, on the costa and 

 apex margined with the same color; apex with a submarginal dusky band; 

 discal areoles on the clavus and corium sparingly inscribed with brown 

 within the fulvous areas. Wings pale smoky hyaline, iridescent. Legs white 

 with black points at the base of the tibial spines. Venter pale, somewhat 

 blackish toward the base and on the connexivum; terminal segment about 

 the width of the preceding, truncate, the two edges parallel. Valve very 

 short-triangular, about the length of the last ventral segment. Plates together 

 a little longer than broad; their sides fringed with long pale bristles. 



Described from two males (No. 222). A third male (No. 259) 

 differs from the others in being larger, with a shorter, obtusely 

 rounded vertex, the markings on which are darker; on the front a 

 double series of transverse lines and the sutures are brown; the elytra 

 are paler with the fuh'ous areas much reduced, leaving the transverse 

 band but feebly contrasted. It is not impossible that individuals 

 may yet be taken connecting this species with Athysanus irrorelliis 

 Stal, but the present material cannot be referred to Stal's species 

 without doing violence to any reasonable interpretation of his de- 

 scription or of the specific characters known to obtain here. 



This is a true Allygus, agreeing with A. iiiixfiis Germ, in all 

 important characters, and is the only North American species of 

 this genus known to me. Jassus irroratiis Say and its numerous 

 allies have but one connecting nervure between the branches of the 

 first and second sector on the elytra, and belong to Phlepsiiis Fieber. 

 This apparently trivial, and not infrequently variable character, seems 

 almost inadequate for use in separating groups of genera, but cor- 

 related as it is with other structural peculiarities of which it is the 

 most pronounced, it appears to answer well the purpose of its em-
