80 SYRPHUS CALCEOLATUS. 



2. — E. testaceiscutellatus , Macq. Dipt. ex. Supp. 4. 138. 

 61; pi. 13, f. 2. — Blanch. 1. c. 407. 3. 



Two males and three females from Chili (Dohrn), the 

 male specimens labelled »testaceiscuteUatus'\ 



Both species , qiiadraticorms and testaceiscutellatus , are 

 closely allied ; of the former only the 9 is known , of the 

 latter only the cf. I consider them without hesitation as 

 the two sexes of the same species. By its small size and its 

 stature it much resembles our E. sepulcralis\ it is however 

 distinguished by the yellow scutellum , which only shows 

 two black spots placed one on each side. Of the hind legs 

 the femora are rather thick , the tibiae curved and the first 

 joint of the tarsus swollen.

A 9 from Chili (Dohrn). 



Both the figures cited are unexact with reference to the 

 yellow pattern of the abdomen , of which Macquart's des- 

 cription gives a better idea. Moreover in Macquart's figure 

 the wings are, as usual in his drawings, of a dispropor- 

 tionally large size. In that of Blauchard the very broad 

 head with protuberating eyes gives a strange aspect; the 

 yellow bands on the thorax are wanting and in the ner- 

 vation of the wings the subcostal cell is represented closed 

 instead of open at the end. 



12. Syrphus catceolatus, Macq. 



Macq. Dipt. ex. II. 2. 91. 8; pi. 16, f. 1. — Blanch, 

 in Gay, Hist, fis. y pol. de Chile,. VII. 411. 6. 



Both sexes froin Chili (Dohrn) 



By its conical projecting face this small species shows 

 a certain affinity to the genera Melithreptus, Mesograpta
