PSrCHE. 



[August — December 1SS9.. 



straight ; legs long, densely spinose ; 

 appendages of the male forcipate, of 

 the same shape in all species. 



I have given a preliminary notice on 

 the previous stages, Compt. rend. soc. 

 ent. Beige., iSSo, May i ; the figures 

 are not yet published. 



Larvae slender, elongate ; the basal 

 joint of the antennae very strong and 

 twice as long as the other six together ; 

 mask elongate, narrow, ver}' dilated on 

 tip, split eft losange far beyond the 

 base of the palpi ; occiput on each side 

 with a prominent spine ; legs long, 

 slender, abdomen on tip with three flat 

 pointed gills, the intermediate shorter ; 

 there are rectal gills, and stigmata as 

 commonlv. 



The genus Calopteryx largely repre- 

 sented in the northern boreal and temper- 

 ate zone nowhere passes to the south 

 beyond the 30th degree. The excellent 

 study of De Selys has shown that the 

 species are few, but the varieties and 

 races rather numerous. For the old 

 world three species : C. virgo^ C. splen. 

 dens and C. haemorJioidalis live in 

 Europe and on the northern border of 

 Africa. The first two are to be found 

 also in the northern and western parts 

 of Asia. For the eastern part of Asia 

 and Japan, three species are known, 

 C. atrata^ C, cornelia and C. grand- 

 aeva. None of these species are found 

 in the new world. De Selys (Odonates 

 de I'Asie mineure, 1SS7. Ann. soc. 

 entom. Belg.) has given a splendid 

 study of Calopteryx. The important 

 race Corientalis Selys, p. 40, he con- 

 siders as proving that C. syriaca is a 



race of C splendens^ the more so as 

 some large males Synop. 3 Add., p 7. 

 seem to support this oj^inion. He was 

 sorry to have seen onl}- the male. Mr. 

 E. Eichwald (Reise auf dem kaspischen 

 meere, 1S37, ^'- 2, p. 272) has 

 described the female. In Lakwish Min- 

 grelia he saw man}- Odonata metallic 

 blue and metallic green. He believed 

 the latter to be a new species, Agrion 

 colchicitis (sic!) aeneo viridis, thorace 

 altiore, sulcis inter areas aeneo-virides 

 nigris notato, inferne nebuloso-coerulea, 

 trunco superne aeneo-viridi, ultimis seg- 

 mentis minimis tumidioribus, flavidis ; 

 alls omnibus aequalibus, medio posticis 

 dilatatis, apicibus rotundatis, aenea vi- 

 ridi-nigrescentibus, omnibus antice 

 macula niarginali nivea notatis ; pedibus 

 nigris, subtus nebuloso-coeruleis, an- 

 tice longis setis piliformibus instructis ; 

 venis alarum parvis (cf Stettin, ent. 

 zeitung, 1856, p. 365). 



Group i. Wings narrow; the hind 

 margin parallel to the front margin.
