Oxycera.— The abdomen is not properly “ depressum,” as it is convex 
above: the eyes are not quite naked, even in the females; and certainly 
not in the males of all the species red above and green in front, as stated 
here. 
Clitellaria. —It would have been better to have called this genus 
Ephippium . Unless a new generic name is introduced, Clitellaria belongs 
by right to the species with spines to the scutellum, but none to the 
thorax; and Cy clog aster to those in which both these are unarmed. We 
cannot approve of the omission of a character so striking as the lateral 
spines of the thorax; the stoutness and erect position of the spines of the 
scutellum should also have been noticed; and this is not properly semicir¬ 
cular, but trapezoidal. 
Nemotelus. —The abdomen is not incurved at the tip in any species of 
the genus; at least not in life. The description “ eyes naked” may pass, 
as regards the British species; though even in some of them the extremely 
short and scanty pubescence is visible with a moderate magnifier. That 
the eyes of the male are red above and green in front is a very imperfect 
description, and calculated to mislead. 
Pachygaster. —The antennae are characterized as 7-jointed, while the 
eighth joint is mentioned directly after, an oversight which does not affect 
the English text; it is not noticed that this joint is very minute. The 
characteristic shape of the comparatively large discoidal areolet should not 
have been passed over in silence. The subdivision of the Stratiomydce 
distinguished by that abnormal disposition of the wing-veins (comprehend¬ 
ing the genera Platyna , Biastes , Ptilocera , and Chauna ,) has the genus 
Pachygaster for its sole representative in the European Fauna. 
Chrysomyia. —The antennae are not six, but eight-jointed; the very 
minute seventh joint and the eighth composing the arista, which is not 
completely apical, but rather dorsal, being inserted close to the junction of 
the fifth and sixth joints, as it is easy to see in the larger species. 
“Abdomen ovale” is not a good description, it is rather spatulate; and the 
eyes are not naked, even in the smaller species, but the pubescence only 
thinner and shorter in them. 
Sargus. —Here also the antennae are seven-jointed, as in Chrysomyia , 
and they differ little in structure in the two. Mr. Walker is mistaken in 
calling them six-jointed, and the account of their structure in general is 
imperfect; the figure is correct, only the position of the arista is not given 
quite exactly. The abdomen is described as consisting of seven segments 
in Sargus , while only five were assigned to it in Chrysomyia , immediately
