One female. Arizona, G. VV. Dnnn (L. iJmuer . It was originally 

 described from soutliern Arizona. 



I have here adhered to my ori;iinal limitation' of Thomas's species, 

 altliouy:h 1 was mistaken in snpposin;; that tlie male 1 then had before 

 me was one of those used by him in his descrii)tion, since he describes 

 the cerci as enlarjre<l at tiie extremity, which they certainly were not 

 in the one then in my hands. Thonms's orijiinals, so far as now pre 

 served in the National Musenm, all l>elon<j: to my Mil. a rid us, but tor- 

 tunately a specinuMi iu Professor Hruner's ccdlection, altliou;;:h it is 

 only a female, enables me to tix the .-species. It may be separated from 

 Mel. ariiluH by the character which Thomas describes thus: "Posterior 

 mar|;:in [of pronotum] truncate on the back [i. e.. diskj, or curved 

 slijrhtly forward" [i.e., emarjrinatel, the posteiior mar;;in in Md. ariduH 

 being distinctly obtusaugulate, though subtruncate.

Pale brown suft'used with tlavous and markcul with black. iTead 

 not prominent, or in the male scarcely i)rominent, pale tlavo-testaceous 

 heavily mottled with brown, above almost wholly brown, with a broad 

 postocular piceous band margined with tlavous (these markinjiS not 

 seen in the female); vertex tumid, distinctly elevated above the pro- 

 notum (male) or feebly tumid, not thus elevated (female), the inters]>ace 

 Itetween the eyes nearly half as broad again as the first antennal joint; 

 fasti^ium rather strongly declivent, deeply (male) or feebly (female) sul- 

 ate; frontal costa subequal, but slightly expanded at the ocellus, where 

 it is equal to (male) or broader than (female) the interspace between the 

 eyes, sulcate distinctly and throughout (malei or feebly and at and a 

 little below the ocellus (female) ; eyes rather large and rather prominent 

 especially in the male, elongate, very much longer than the intraocular 

 portion of the geuae; antennae tlavous, a little shorter than (male) or 

 about two thirds as long as (feumle) the hind femora. Pronotum sub- 

 equal on the prozona, expanding on the mctazona, nearly uniform in 

 coloring except for a large tlavous-margined, piceous, postocular patch 

 ( lossing the prozona, more or less broken and irregular in the female;

 lobes with no trace of lateral carinae, though the position of these is
