2 $ Soda Springs, Shasta Co., Calif. (J. Behrens.) 

 One of these examples has the 4th, 5th and 6th abdominal 

 segments a pale buff instead of orange, but I think this an acci- 

 dental variation. I dedicate this exquisite species to my old 

 friend, Mr. James Behrens, who has done so much towards an in- 

 vestigation of the entomological fauna of California. 



FAM. ZYG^NID^. 



Lycomorpha rata. n. sp. 



Allied to L. constans, Hy. Edw., but differing by the follow- 

 ing characters. The disc of the wing in the present species is 

 dull orange, with the costa black, widening a little towards the 

 apex, and joining the rather broad posterior marginal band. 

 Secondaries also broadly margined with black. Head, antennae, 

 thorax, legs and abdomen, above and below, blue-black. Collar, 

 patagia and sides of abdomen dull orange. Lower side of the 

 wings same as the upper. 



In L. constans the costa of primaries is orange, as well as the 

 basal ^ of the wing ; the costa only of the secondaries is orange, 

 and the abdomen is wholly blue-black. 



Exp. wings, 18 m. m.

Lycomorpha Latercula. n. sp. 



Primaries brick red. Posterior margin broadly, internal 

 margin narrowly, and apical 3d of costa blue-black. Secondaries 

 blue-black, except the costal edge, which is brick-red. Under 

 side the same as the upper. Antennae, head, thorax and abdomen 

 wholly blue-black. Legs with a brownish shade.
