12 THE CANADIAN ENTOMOLOGIST. 



c. Two female specimens from Arizona differ distinctly in having a 

 broader and more projecting face, smaller eyes, whiter and more dense 

 pollen on face, thorax and abdomen. Another specimen with these two, 

 however, though agreeing in the latter respects, has the face of the usual 

 width. 



d. A male specimen from North Park is of a distinct species, though 

 closest allied to the present. The sides of the face are unusually narrow, 

 the front short, convex and almost horizontal, the abdomen marked more 

 like that of G. senilis, the size smaller (ii m.m,), the claws and pulvilli 

 large. 



GONIA SEQUAX, n. Sp. 



^ . Length 12-13 m.m. Like the males of exul, except that the 

 abdomen is either wholly yellowish red, with a black spot under the scu- 

 tellum, and a brownish hind margin to the third segment, or with a slender 

 black stripe on the second, and a small triangle on the third and fourth 

 segments. The claws and pulvilli are very much smaller, much shorter 

 than the terminal joints of the tarsi. 



Three specimens, California. 



NOTES ON THE GENUS EXOPROSOPA. 



BY D. W. COQUILLETT, LOS ANGELES, CAL. 



In my paper on " The North American Genera of Anthracina," which 

 appeared in the last volume of the Can. Entomologist (pp. 157-159), 

 I proposed the name Vclocia for those species of Exoprosopa which have 

 four submarginal cells in each wing. Through the kindness of Dr. Willis- 

 ton, I have been put in possession of a paper by Prof Camillo Rondani, 

 entitled " Dipterorum Species et Genera Aliqua Exotica," published in 

 1863 in the Archivio per la Zoologia, vol. iii., and on pages 56 and 57 of 

 this paper Prof Rondani proposes the name Hyperalonia for the above 

 group ; this name being the earlier, must supersede the one proposed by 

 me. 



In the same paper Prof. Rondani proposes the name Argyrospila for 

 those species oi Exoprosopa in which the third and fourth veins are joined 

 together before the margin of the wing, instead of reaching the margin
