June-Sept, 1919.] DAVIS : ClCADAS. 183 



DD. Outer edge of front wing of a more continuous curve. 

 Medium sized species, except schaefferi, which is large. 

 E. Legs almost entirely orange or greenish in color. Ab- 

 domen pale beneath including the rather long 

 valve. 

 Pronotum mostly pale with a black median vitta 

 gemmate anteriorly, the lateral oblique groves 

 more or less broadly black. Two broad pale 

 marks extending from the anterior extremities of 

 the mesonotal X ; a rather dull colored species 

 with the uncus deeply cleft at extremity. Ex- 

 pands about 70 mm vandykei Van Duzee 



Pronotum as in Vandykei ; mesonotum reddish 

 straw color, black centrally ; tergum black with 

 posterior edge of the segments pale. A shining 

 species with the uncus seen from above shallowly 

 noticed at the extremity, and sinuate on lower 

 margin when seen in profile. Expands a little 



over 60 mm lurida new species 



Head, pronotum and mesonotum almost entirely 

 black, front margin of fore wing bright orange 

 to the end of radial cell ; basal cell opaque. Ex- 

 pands about 60 mm ornata Van D. 



Head, pronotum and mesonotum black, much varie- 

 gated with dull orange ; venation of fore wings 

 uniformly light in color, basal cell clear; tergum 

 shining black with the segments narrowly mar- 

 gined with orange posteriorly. A larger headed

EE. Legs, especially the front pair considerably blackened. 

 F. Shining species with rather broad wings, and the 

 hind margin of pronotum orange or reddish. 

 Front of head strongly produced ; pronotum 

 edged on sides and hind margin with orange, 

 hind margin of abdominal segments both 

 above and beneath orange. Last segments 

 of abdomen beneath with short scattered 

 pubescence. Expands about 75 mm. (Ex- 

 cept in size this and fratercula resemble 

 each other, and some specimens that may 

 belong to the last named species are much 

 larger than the type.) ... .schaefferi Davis 

 Venation of the fore wings fuscous, except 

 the costal margin, which is often narrowly 

 edged with black, but otherwise greenish-
