S2 PEOCEEDINGS OF THE ACADEMY OF 



across the middle angle; lateral foveola? obsolete; frontal ridge bisulcate 

 above the ocellus, silicate below, expanded at the ocellus. Pronotum flat 

 above, rough ; median carina an elevated line, very distinctly severed by 

 cross incision 3, before the middle; incisions 2 and 3 come together at the 

 carina ; anterior portion rugose ; posterior lobe covered with elongate tuber- 

 cles, its sides granulose. Wings and elytra extend beyond the abdomen. 

 Posterior femur about the length of the abdomen. Antenna? filiform, reach- 

 ing the tip of the pronotum. 



Color (siccus). Dirty-brown, with fuscus spots. Each elytrum has a 

 narrow yellow stripe near the dorsal border; the base brown, fading toward 

 the apex, which is semi-transparent ; marked with groups of fuscus spots 

 which at two points form irregular bands somewhat as in (E. cequalis. Wings 

 yellow at base ; a dark baud of moderate width crossing just beyond the 

 middle, curving inward to the posterior angle ; apex transparent, veins dusky. 

 Posterior femora crossed on the outside by two very indistinct oblique red- 

 dish bands ; inside, beneath and tibia? orange yellow (probably bright red in 

 the fresh specimens) ; spines of the tibiae tipped with black. Antenna? pale 

 at base, apical portion dusky. 



Dimensions. Female. Length 116 in. ; to tip of elytra 1-38 in. ; to end of 

 pronotum -44 in. ; femur -03 in. 



Hab. N. Mexico. 



This species agrees so nearly with (E. Mexicana, of Saussure, that I would 

 have marked rny unique specimen as such, but for the fact that its wings are 

 yellow at the base. 



TOMONOTUS, Sauss. 

 T, xietanus, Sauss. 



T. mexicaxus, Sauss. 



I have labelled my specimens with some hesitancy, especially those belong- 

 ing to the first species. T. nietanus, when living appears black, and may 

 easily be recognized when flying by its black body and bright red wings. It 

 is closely allied to (E. sulpkurea, Burm., which belongs to this genus. 



T. PSEUDO-NIETANCS, UOV. Sp. 



Male. Size and' appearance much like T. nietanus, Sau?s., from which it 

 differs only as follows : The facial costa is slightly broader and less excavated 

 below the ocellus ; the occiput and pronotum less rugose ; the antenna' nearer 

 cylindrical. The color is darker, the sides being deep black throughout to 

 the tips of the elytra ; the posterior part of the occiput and dorsum of the 

 pronotum an ashy-yellow, the front lobe and lateral margins of the pronotum 

 dotted with black ; the upper edge of the posterior femur has two yellow 

 spots, one next the base the larger. Beneath shining black. Wings as in 

 nietanus ; base rosaceous, posterior border broadly margined with black, and 

 a fascia of the same running along the anterior margin nearly to the base. 



Dimensions. Male. Length 1 in.; to tip of elytra 1-25 in.; femur -67 in.; 

 tibia -53 in. 



Hab. Found near Canon City, Colorado, in a mountain caflon. 



I have not seen the female. It may possibly be a variety of T. nietanus, but 

 its variations from that species added to the fact that it was found at but one 

 point, justify me in describing it as new. 



STAUROXOTUS, Fischer. 

 S. Elliotti, now sp. 



Medium size, robust, sub-angulate. Head large, widest below ; face sub- 

 vertical, strongly deflexed below tho transverse suture; occiput convex : ver- 

 tex slightly declined, foveolate ; foveohe shallow, the central broad, lateral 

 triangular, the points of the three meeting in a sharp angle midway between 

 the upper angle of the eye and the antenme ; frontal ridge not Bulcate, nar.
