 Elongate, oblong. Front without strioles; preocular tooth slightly 

 prominent; supraorbital stria very short basal. Mandibles slightly 

 longer than head {&), or equal in length to head (9). Pronotum 

 bisinuate at base, with a median, dimidiate, longitudinal stria, lightly 

 impressed; marginal stria entire, deeply impressed, rounding the 

 ]josterior angles, and ending anteriorly in deep, triangular fossa (cf ) or 

 a short hook ( 9 ) ; punctate sparsely in a narrow band within the 

 marginal stria, the punctures closer and more numerous basally. Elytra 

 bistriate, the first about one-third the length of the elytra, the second 

 about one-half the length of the first, with an appendix extending from 

 the basal fourth almost to the apex ; subhumeral stria deeply impressed 

 for most of its length, the basal part fine and reaching almost to the 

 base (cf) or a little shorter (9)- Inflexed portion of elytra rugulose. 

 Propygidium smooth on disk, coarsely punctate laterally, finely punc- 

 tulate at apex. Pygidium coarsely and densely punctate. Mentum 

 concave (cf), almost flat (9) evenly punctate. Prosternum elevated, 

 truncate at apex. Ventral segments punctate at sides only. Lower

Variants. One male has a small stria which is attached 

 basally to the appendix of the second stria at an obtuse angle, 

 and so prolongs the appendix that it almost reaches the second 

 stria. 



Two specimens have an entire second stria on one side, 

 the other side normal. 



The male is slightly broader than the female, has a large 

 deep fossa at the anterior angle of the pronotum, a differently 

 shaped mentum and a longer subhumeral stria. 



Reported to occur in dying Dasyllirion (Schwarz) and 

 Agave americana? (Schaeffer). 



Hololepta (Leionota) sirpus s]). no v.

 preocular tooth moderately prominent; supraorbital stria, basal, short. 

 Pronotum with a lightly impressed median stria extending from base 

 half way to apex; punctate laterally in a narrow band of large, distant 

 punctures; marginal stria entire strong, rounding the posterior angle
