Race angustior. Pasco, 5 S , 2 9 , all taken May 25, 1896 (T. Kin- 

 caid). 



Synhalonia lycii n. sp. 



9 . Length 13 to 14i mm. ; general form, size and structure of 

 S. frater, which might be readily confused with it on superficial ex- 

 amination. On comparing lycii with an Illinois example of frater 

 received from Mr. Robertson, the following differences are at once 

 apparent : — 



S. lycii 9 • 



Segments 2 and 3 of abdomen 

 with light bands ; 4 and 5 sooty 

 black, without light bands, or at 

 most a very narrow apical gray 

 band on 4 ; apex with black 

 pubescence. 

 Ventral surface of abdomen Ventral surface of abdomen 



S. frater 9 . 



Segments 2-5 of abdomen with 

 distinct light bands ; apex with 

 light brown pubescence. 



with light pubescence. 



Wings noticeably brownish. 



with black pubescence. 

 Wings clear. 



The above are conspicuous and constant distinctions : yet the 

 head, thorax and legs of the two insects, with their pubescence, are 

 virtually the same. 



Hab. — S. lycii occurs in the Mesilla Valley, New Mexico, near 

 the Agricultural College ; on Lycium torreyi, on the College Farm, 

 April 16 ; on flowers of plum, College Farm, April 9. Miss Jessie 

 Casad took one on lilac in Mesilla, April 14. 



Calliopsis scitulus Cresson, 1878. 



Santa Fe, N. M., July 7 (Ckll. 1,356) ; Sta. Fe, July 25, on Cleome 

 serrulata (Ckll. 3,747). Also Colorado, collected by Prof. C. F. 

 Baker (No. l,595=Fort Collins, Aug. 8, 1895, and l,592=Fort Col- 

 lins, Aug. 8, 1895, on Cleome). 



In the specimens, Ckll. 1,356, the lateral marks of theclypeus are 

 almost lacking; as also in Baker's 1,592, which has only two spots 

 on the fifth abdominal segment. 



I am not sure about the $ of C. scitulus; the above records all 



pertain to females. At Sta. Fe, on the same day as 1,356, I took a 



$ which resembled, but was not identical with, 0. pictipes Cresson. 



Prof. Baker sends a $ taken at the same time and place as his 1,595 



above, and it agrees sufficiently with Cresson's description of picti-
