 Duzee. 



The following, while clearly a Clidophleps, lacks some of the 

 prominent characters of the two species of the genus so far described. 



Clidophleps astigma new species. 



Type, male, San Fernando, Lower California, Mexico, May, 1889 (W. E. 

 Bryant). Collection, University of Nebraska. 



Head as broad as the front margin of the pronotum ; front considerably 

 produced, much more so than in distanti. Median sulcus of the front well 

 defined. Pronotum with the humeral angles rounded; the anterior angles also 

 rounded and rather prominent. The opercula with the extremities rounded. 

 Last ventral segment rounded and slightly emarginate at apex. Uncus when

surface of the apical half. Basal areolae of the fore wings clear. Costa of the 

 fore wings narrowly margined with brown, membranes orange. Hind wings 

 with membranes lighter colored and clouded. The fore wings are propor- 

 tionately narrower than in distanti, the costal margins are more evenly curved, 

 the central portions are not so much bulged outward, or upward if the wings 

 are expanded, and the " triangular fuscus nodus " at the outer end of the 

 cubital cell is reduced to a mere thickened vein. Head black with the supra- 

 antennal plates and triangular area behind the middle ocellus yellow. Beneath, 

 the head is black margined with yellow on each side of the transverse rugae. 

 In some of the paratypes the median sulcus is yellowish. Pronotum narrowly 

 margined with yellow and with a narrow yellow stripe about one millimeter 

 in width extending from the front margins to the hind margin, on either side 

 of which there is a large irregular brownish colored area clouded along the 

 depressions. Mesonotum black with an irregular yellow spot near the base of 

 each fore wing; the mesothoracic cross is yellowish, as are two narrow and 

 curved spots near its front extremities. On either side between the cross
