133 



G. simillimus. 



3rd, 4th, 5th, Gth, 7th and 8th with 

 a yellow ray composed of dorsal longi- 

 tudinal narrow spots a little broader 

 anteriorly, pointed behind, and not 

 touching at all the posterior margin. 



9th with a very large oval spot 

 touching both ends. 



10th with a small triangular pos- 

 terior spot. 



The anterior articulations of the 

 three last segments, the oreillettes, 

 all the back of the posterior genital 

 lobe, the sides of the base, and of the 

 end of the abdomen, and a lateral 

 trilobed spot on the five intermediate 

 segments, yellow. 



Appendages as long as last seg- 

 ment. Superior black, a little separ- 

 ated at base, cylindrical, a little 

 swollen ; if viewed from above, ter- 

 minating suddenly in a little very 

 acute point ; viewed in profile one 

 sees a little before the point beneath 

 something like a small projecting 

 blunt tooth. Inferior appendage 

 forked, yellow with black lateral 

 branches not more widely apart than 

 the superior. 



Legs yellow; the femora with a 

 triple black line, the tibiae black 

 inwardly, all the tarsi black. 



Q. schneiderii (Beikos). 



3rd, 4th, 5th, Gth and 7th with a 

 yellow ray composed of dorsal longi- 

 tudinal narrow spots, those on (5th 

 and 7th especially a little narrower 

 behind. 



8th and 9th with much smaller 

 and shorter markings. 



10th all black above. 



The anterior articulation of the 

 three last segments, the oreillettes 

 and sides of segment 2 ; a large basal 

 lateral spot on segment 3 ; small 

 basal spots on sides of segments 4, 5 

 and 6 ; a large irregular spot on 7 ; 

 8th and 9th with greater part of 

 sides, and 8th, 9th and 10th ven- 

 trally, yellow. 



Appendages black. 



Compare the figures of the profile 

 view. 



Legs entirely black, with the excep- 

 tion of traces of yellow on anterior 

 femora. 



OnychogoinphusforcipaUis, Linne. — Male, Gyok-su, May 24th, 

 1913; female, Riva-su, May 2nd, 1913. These show little 

 tendency towards the meridional race. The male has, however, 

 traces of a yellow dorsal line on the eighth segment ; the ninth 

 is yellow, posteriorly interrupted with black in the middle. 



CORDULEGASTERIN^ . 



C or duleg aster charpentieri, Kol. — Two males, Belgrade Forest, 

 June 23rd, 1913, June 21st, 1914. These examples are very 

 similar to a male given to me by Bartenef from Lagodechi in 

 the Caucasus, the locality whence De Selys received a series 

 which he referred first to his C. pictus, and later, I believe, to 

 C. charpentieri, Kol. That these really represent C. charpentieri, 

 Kol., seems to me not altogether beyond doubt. I hope to return 

 to this point again. 



^SCHNINiE. 



Brachytron hafniense, MUller. — Male and two females, 

 Kutchiik Tchekmedj6, on Sea of Marmora, European side, 

 April 25th (Male, near lake, G.).
