] CLARK — NEW SPHINGIDAE 67 



sheath is blunt at the point, instead of acute as in P. hannibal. 

 This form, however, was described from N. Friburgo as Sphinx 

 hamilcar Boisduval (1875, Spec. Gen. Lep. Het., p. 79, no. 12), 

 and should be known as P. hannibal hamilcar Boisd. The name 

 mayi lapses, as a synonjmi. 



In speaking of the type of Lapara halicarniae Strecker 

 (Proc. N. E. Z. C, Vol. VI, p. 102), I said "the color, which I 

 believe to be faded, as are many of the specimens in the Strecker 

 collection." My friend Mr. William J. Gerhard, of the Field 

 Museum, called my attention to the fact that the Strecker col- 

 lection is in as good condition as could be expected of specimens 

 collected so long ago, and that it compares favorably with the 

 other historic collections. This is entirely true, as it has been 

 well cared for. 



Protoparce kuschei sp. nov. 



Al. ant. long., c?, 39 mm.; 9, 46 mm. Al. ant. lat., cf, 16 mm.; 9, 

 19 mm. Marg. ext., c?, 21 mm.; 9, 25 mm. 



Habitat. — Venodio, Sinaloa, Mexico. Four males and two females in 

 coll. B. Preston Clark, collected by Mr. J. August Kusche, June - August, 

 1918. 



This species is closely allied to P. diludda Edwards. The males are very 

 difficult to distinguish, and I am not sure, after comparing a series of each 

 species, of any certain means of distinction except the genitalia. The tooth 

 of the penis sheath of this species is shorter than that of P. diludda, and 

 blunt instead of sharply acuminate. 



The female, while showing the same maculation as P. diludda, is readily 

 distinguishable from it. The fore wing above is more uniform in color, the 

 ground tone of both fore and hind wings above is gray with markings of 

 darker gray and black, differing thus from P. diludda, with its ground tone 

 of brown and sharply contrasting white markings. Fore and hind wings 

 below are gray, as compared with the brown of P. diludda. The sharply 

 marked white area of P. diludda, extending in the female between M2 and 

 the inner margin from the sub-basal portion of the wing more than half- 

 way to the hinder angle, is in this species entirely lacking.
