segments fringed with pale hairs, the apex armed with an acute, recurved 

 spine. Length 5| lines, expanse of wings 8J lines. Fig. 2. 



Hah.— Texas. 



This gpecies is closely allied to A. nubecula, Cresson, but is readily 

 distiiifjuished by having two submarginal cells, and the sudden dilation 

 of the basal segment of the abdomen. 



I respectfully dedicate this species to Mr. Belfrage, of Texas, to 

 whom the American Entomological Society is indebted for much in- 

 teresting material.

17. Agama Alcanor, n. sp. 



Male. — Head black, rounded, wider than the thorax, very finely punctured, 

 mandibles black, tridentate at tips, eyes very large, prominent, ocelli also large, 

 antennae fulvo-testaceous, more than half as long as entire insect, the joints 

 curved, presenting a slightly scolloped appearance, when viewed laterally. 

 Thorax chestnut-brown, elongate-subquadrate, truncate in front, disc of meso- 

 thorax sub-convex, shining, feebly and remotely punctured, with two lateral, 

 longitudinal impressed lines, the lateral lobes finely and closely punctured, 

 metaihorax truncate, shining, the dorsal groove extending to apex. Wings 

 pale yellowish-hyaline, nervures pale fuscous, stigma large, marginal cell 

 short, roundly obliquely truncate at tip, three distinct submarginal cells, the 

 first nearly as long as the stigma and marginal cell combined, dilated towards 

 the base, second subtriangular, truncate at base, and lying entirely beneath/ 

 the first; receiving the first recurrent beyond the middle. Legs castaneous, 

 thinly clothed with pale hairs, more dense on the tibiae and tarsi. Abdomen 

 elongate, petiolate, chestnut-brown, shining, petiole pyriform, minutely punc- 

 tured, punctures coarser about the apex, second and following segments feebly 

 punctured, and sparsely clothed with scattered pale pubescence. Length 6 lines, 

 expanse of wings 11 lines. 



Huh. — Arizona. 



This species resembles A. castanea., Cresson, but may be known by 

 the greater length of antennae, and the head being entirely black.
