PERVaiAISKf (195OB). USSR. As H. p. plximbeum ; females mated 

 with males of H. anatolicum excavatum feed normally, become 

 enlarged, and Tay normal quantity of eggs, which are in_ 

 fertile. When male H. £. plumbeum fertilize female H. 

 anatolicum excavatum ^ from 20^ to 100^ of the eggs are 

 fertile; the majority of Fi females have maternal traits, 

 the majority of the Fi males have combined maternal and 

 paternal traits. When "extremely normal" F]_ males and 

 females were mated, the progeny consisted of 61 gynandro- 

 morphs in a batch of A35 individuals /"see also R. sangui -

PERVCMAISKf il95A). USSR. As H. p. plumbeum ; males vary from 

 3.2 ram. to 6.3 mm. in length and from 1.8 mm. to 3.6 mm. 

 in width. Three types of scutal punctations are observed 

 on individual specimens, (l) most common, numerous, even- 

 ly distributed minute among large, (2) common, numerous 

 minute, (3) on small males, minute and large mixed. The 

 middle festoon is narrow, the tail of the spiracular plate 

 is wide, and the inner margin of the ad anal shield is 

 slightly extended. The female size is quite variable 

 and scutal punctation varies as among males, but diagnos- 

 tic characters are "relatively constant."
