2. Idiolispa analis (Gravenhorst) 



Front wing 4.7 to 8.5 mm. long; segment 1 of male flagellmn about 

 3.0 as long as wide; clypeus broadly elliptic, evenly convex, the con- 

 vexity varying from weak to strong, the highest point of convexity at 

 middle of clypeus; temple at midheight of eye distinctly convex, about 

 0.75 as long as eye; cheek about 0.75 as long as basal width of mandible 

 in male, about 1.0 as long in female; mesopleurum polished, with small, 

 sharp, rather dense punctures and a variable amount of wrinlding 

 which may partiaUy obscure the punctures; nervulus usually in front 

 of basal vein by about 0.2 its length, sometimes opposite basal vein; 

 apical carina of propodeum very strong sublaterally, where it is rather 

 weakly sloped, especially in female, or in female often horizontal; 

 first tergite about 2.75 as long as wide in male, about 2.50 as long as 

 wide in female; punctures on fkst tergite of male very small, separated 

 by about 5 times their diameter; tergite 3 of male polished or wealdy 

 mat, with line, weak punctures that are separated by about 0.75 the 

 length of the hairs; tergite 3 of female polished, ahnost impunctate, 

 with scattered fine, weak punctures that are separated by about 4 

 times the length of their hairs, near lateral edge the punctures (and 

 hairs) denser. 



Coloration variable, according to the subspecies. 



Idiolispa analis is Holarctic. It is adult in spring and early summer. 

 We know of four subspecies, and there are probably additional ones 

 in Asia. Idiolispa analis var. suigensis, described by Uchida from 

 Korea in 1930, is not a form of this species but belongs to Trychosis. 

 Trychosis suigensis is a new combination. The subspecies at hand 

 are differentiated as follows: 



1. Tergites 2 and 3 black or blackish; range: Sachalin and Japan. 



2d. analis nigra Uchida 

 Tergites 2 and 3 ferruginous 2 



2. Tergites 6 and 7 largely or entirely infuscate or black; range: Europe and parts 



of northern North America 2a. analis analis (Gravenhorst) 



Tergites 6 and 7 ferruginous 3 



3. Hind basitarsus of male with its apical 0.3 or more white; flagellum of female 



nearly always with a median dorsal white stripe that covers two or more 

 segments; wings weakly infuscate; hind femur always black; range: Alle- 



ghanian and CaroUnian faunas 2b. analis limata (Cresson) 



Hind basitarsus of male entirely fuscous; flagellum of female without a median 

 dorsal white stripe, or with one that covers only one or two segments; wings 

 rather strongly infuscate; hind femur ferruginous or black.
