It is evident that Sphseromias will follow Chironomus (pi. 90); 

 but it will be an anomaly in this portion of the Tipulidse 

 should there be no sexual difference in the antennae, and all 

 the specimens I have seen of two species were alike simple ; 

 they are very different also to Chironomus and Tatiypus both in 

 the nervures of the wings and the form of the palpi. The 

 trophi are likewise remarkably complete, and the powerful 

 claws and singularly spined terminal joints of the feet are cha- 

 racteristic of the genus. 



I have adopted the names that have lately been given to 

 these insects, but no characters have hitherto been recorded. 



1. S. albomarginatus Curtis Brit. Ent.pl. 285. 



I am indebted to A. Cooper, Esq. for examples of these 

 insects, accompanied by the following memorandum : 

 " One specimen was taken by me the latter end of 

 May, 1828 ; and about the same time this year I was 

 fortunate enough to capture several more. They 

 were all beaten from a white-thorn bush, in Copen- 

 hagen fields. 



2. S. annulitarsis Steph. 



I do not know this species ; but as the annulation of the 

 tarsi is common to the genus, it does not appear to 

 be a well chosen name. This insect was also taken, 

 I believe, in the neighbourhood of London. 



3. S. varipes Steph. 



Black, shining. Antennae ochreous, blackish beyond 

 the middle, basal joint brown. Halteres, body and 

 legs sulphur and straw colour ; the tips of the thighs 

 and tibiae, and a ring round the latter in the hinder 

 pair, as well as the terminal joint of the tarsi and 

 claws, black. 

 Taken at the same time and place, by Mr. Cooper, as the 

 first. 



The plant is Orchis maculata (Spotted Orchis).
