 was an immature male from ('atalonia. This was regarded by 

 de Selys-Longcliumps as a new species of Ufolhenm, a genus 

 to which he also rel'ened Van der Lindens insect, and he 

 described it in 1878 under the name of Urofheinis culvena. 

 After an interval of about twenty years, records began to multi- 

 ply more raiiidly, with the result that the true home of the 

 species was found to lie i'uidier towards the East than was 

 formerly suspected. Since 1897 His, the author of the mono- 

 typic genus Sch/siolhciiiis, lias extended the known distribution 

 to the Kashgar Daria in the East and to the Algerian Sahara 

 in the South, while Bartenef has furnished several records 

 from Palaearctic Asia (the (\uicasus, Turkestan, Persia, and 

 Afghanistan). 



I met with this insect in great numbers at two or three differ- 

 ent localities in Macedonia, and, as my captures were made in 

 circumstances which cannot be regarded, as accidental, they 

 confer upon the species a status in the European fauna which it 

 could not derive from the two old and unconfirmed Mediter- 

 ranean records. According to the information Morton has 

 recently published, members of the British Expeditionary 

 Force in Mesopotamia also found the species very commonly. 

 In Mesopotamia, it would seem, Sehfsiolheinis is on the wing 

 from April to J une, while in August and September immature 

 exafmpl(\s again appear. The individuals of the earlier batch, 

 moreover, are larger. As it happened, the four specimens taken 

 by myself in Macedonia in the third week of June were all 

 femahjs, and three of them were decidedly immature. The 

 remaining specimens, six in number, were caught late in July 

 or early in August, and all of them were fully adult. It is 

 possible that the flight of this species, which evidently begins 

 later in that country than in Mesopotamia, is continued without 

 any interruption during the month of July. It remained on 

 the wing until the end of August, at all events, but I have no 

 record of its ap|)earance in September. In resjiect of size, my 

 specimens from Giol Ajak and Lake Adji Geul compare very 

 favourably with those previously recorded. 



Although no examples were secured, the species was again
