CYANIRIS SEMIARGUS. 297 



at Wiesbaden, and in mid- August, 1900, atBraunfels (Sick); June, near 

 Cassel (Borgmann), but July to August, at Rotenburg-on- Fulda (Jordan); 

 May- June and September, in Pomerania (Paul and Plotz); in two 

 broods (Spormann); occurs throughout the whole summer in Posen 

 (Schultz); double-brooded in June, and again in August, in Thuringia 

 (KrieghofT); in May, and July-August, at Zeitz-on-Eister (\Yilde); 

 worn, mid-July, on the Veronikaberg (Gillmer); in the Kingdom of 

 Saxony, in May- June and July-August, at Dresden (Steinert); June- 

 July, in Saxon Upper Lusatia (Schiitze); in Baden, May and beginning 

 of July (Meess and Spuler); locally abundant towards the end of May, 

 1906, near Lahr (Keynes); occurs in May and August, in Hamburg 

 (Zimmermann and Laplace) [early specimens not observed in the 

 province after seven years' collecting (Gillmer)] ; worn, end of July, on 

 Sylt Island (Werneburg) ; in June and August, at Schwerin, in Mecklen- 

 burg (Voelschow), June to August, at Eutin (Dahl); July, near Fried- 

 land (Stange); as late as September, 1896, on the Kiebitzberg, near 

 Waren (Busack); occurs in May, and again in July and August, in the 

 Province of Saxony (Ent. Ver. Erfurt)', early June, in Anhalt (Stange); 

 from June to August, at Dessau (Richter). Gillmer states that 

 " although C. seniian/us occurs from the end of June until August, in 

 Anhalt, he believes there is only one brood, and that he cannot confirm 

 Heinemann's statement that it has two broods in Anhalt. nor Fischer's 

 that it occurs in spring and summer at Wernigerode." Reinecke gives 

 May- June, and August, for the north-eastern border of the Hartz, and 

 Jordan gives end of May and mid- July, at Gottingen. In Switzerland 

 the species is well out in mid-May, in the warmer parts of the Valais 

 and Geneva, and apparently again in mid-July ; it is particularly 

 abundant in the Geneva district in May and June, but the second 

 brood appears to be a very partial one ; in the mountains it rarely 

 appears until mid-June, and, according to elevation, continues to appear 

 until towards the end of July or even the beginning of August, but 

 only in one brood. In a very early year, 1897, the first brood was 

 abundant between April Gth-iilst, at Veytaux, and, in 1899, between 

 May lst-5th, and, in this latter year, the second brood was practically over 

 in mid- July, at Aigle, and over a series of years it may be considered as 

 proved that, in the hotter, lowlying parts of Switzerland, the first 

 brood is always well out in May, and the second brood from early July 

 to August ; Reveidin states that, near Geneva, May-early June is the 

 time for the first brood, and end of July-August for the second brood. 

 In Italy it is also double-brooded, occurring at the end of May and in 

 June, and also in July and August in Tuscany (Stefanelli), in May and 

 June on the hills by Brianza, and in September near Alzate (Turati); 

 well out in mid-May, in Piedmont at Orta, Locarno, and Lugano (Lowe), 

 a second brood no doubt being represented by specimens captured July 

 8th-10th, at Chiesa (Rowland-Brovm), in August, at Aosta (Tutt), and 

 in July, at Certosa di Pesio (Norris); in the mountains, as in Switzer- 

 land, it is single-brooded, occurring in July and August, e.y., at 

 Courmayeur, Cogne, etc. Jn Portugal, there is no record of a second 

 brood, but the first brood is worn in early June (Eaton). In Spain, 

 the species appears to be little known, but one suspects again that it 

 is double-brooded except at considerable elevations — mid-May, at 

 Granada, end of July, at Bejar, mid- July, at Monca}~o (Chapman), in 

 August, in Teruel (Zapater), mid-July at La Granja (Sheldon^, end
