 siderably more pointed toward the apex. Head black ; eyes brown, margined 

 with sulphur yellow ; palpi and antennre black. Thorax black ; tegulse sulphur 

 yellow ; abdomen black, slightly sprinkled with yellow on middle segment. Legs 

 black, tibiae entirely, femora only outwardly, orange. Anterior wings black with 

 steel blue scales, especially marked near the uase. Yellow patches much as in A. 

 octoinaailata excepting the one on the primaries near the base is more kidney shaped, 

 while in A. odomaciilata it is semispherical with the base toward the interior margin. 

 The costal nervure is very much enlarged towards the middle of the anterior wings, 

 and is here margined with sulphur yellow. Secondaries black, with the pale yellowish 

 patches placed as in A. octoinaailata except that the one near the base is much smaller 

 and does not reach the inner margin. Bslow, all the markings reproduced.

Described from 3 9 9 ^'"*^"^ Texas. Collection of E. L. Graef 



This species can be readily separated from A. odomaailata by its 

 narrower, and more pointed wings, and the greater length of the abdomen ; 

 A. octo?)iaculala (^ has a dorsal stripe of sulphur yellow, extending along 

 its entire abdomen, widening towards the anal extremity, while in A. 

 gracilenta the abdomen is entirely black with a few, hardly noticeable 

 yellow scales on middle segment ; also by the yellow patch in the middle 

 of costal nervure. 



Harrisina nigrina n. sp. 



This species in shape and size closely resembles H. amtriama, but 

 can be at once recognized by the absence of the orange prothorax. The 

 entire insect dull black, the abdomen with a bluish lustre.
