SOME DICHRORAMPHAS OBSERVED IN 1913. 305 



that on. June 15th I heard a Cicada singing in a pine tree 

 within a few yards of the spot where, in 1901, I made my first 

 acquaintance with this interesting bug, another proof of how 

 extremely local is the species. 



At present the haunt of our Cicada is known to, I believe, 

 only two professional collectors, one woodman, and six or seven 

 entomologists, so that it would seem unnecessary to invoke the 

 assistance of the newly formed " Society for the Promotion of 

 Nature Eeserves " for its protection ; the time will probably 

 come, however, when it will be found imperative to make some 

 effort to prevent the extermination in the New Forest of this 

 species, as well as the Lepidoptera Apatura iris and Zygcena 

 meliloti.

SOME DICHROKAMPHAS OBSERVED IN 1913. 

 By Rev. John W. Metcalfe, F.E.S. 



Being in want of several species belonging to this genus for 

 "genitalia" purposes, a careful look-out was kept for them, and 

 the following notes may be of interest. The group to me is a 

 very puzzling one, and it is hard to say exactly how many 

 species we possess. Perhaps Mr. Pierce will be able to tell us 

 when the genitalia have been worked out. 



In May D. saturnalia was flying freely amongst Tanacetum 

 vulgare near Ottery St. Mary, indeed it occurs here wherever 

 Tansy is found. The date is perplexing, as Barrett and Meyrick 

 give June and July, Stainton and Wilkinson July and August. 

 The unfolded costa seems clearly to identify the insect and to 

 separate it with plumbana from the other Dichroramphas. But 

 here, and apparently in the Eastern counties, it flies from the 

 beginning of May and is over by the middle of June, whilst 

 I have seen no sign of a second brood. I have received 

 this insect from friends under the name tanaceti, perhaps 

 a guess suggested by the food-plant, the vicinity of which it 

 never leaves. However, it is at least possible that Stainton 

 and Wilkinson were really describing saturnana under the 

 name tanaceti, and to this the fact that their insect was 

 taken amongst Tansy points. In this case tanaceti drops out of 

 our lists. On the other hand, Stainton and Wilkinson, who 

 were, at any rate, dealing with the same insect {vide the captor, 

 a Mr. Thompson, near Crewe), may have had herbosana before 

 them. In favour of this are the date, the Northern locality, and 

 the fact that they both describe saturnana with the unfolded 

 costa elsewhere. In this case we must with Meyrick retain 

 tanaceti, St. & Willk., for herbosana, Barr.
