DOLERUS PUNCTICOLLIS. 171 



Kaltenbacli says (1. c.) that he bred this species out 

 of larva? which fed in June and July on different meadow 

 grasses, and especially on Festuca pratensis. 



A very common species found everywhere throughout 

 Europe. 



14. DOLERUS PUNCTICOLLIS. 



Dolerus puncticollis, Thorns., Hym. Scand., i, 286, 14; Cam., 



E. M. M., xvi, 249; Andre, 

 Species, i, 274 ; Cat., 34,* 36. 



Black ; the tip of the abdomen aeneous, apical fourth of the anterior, 

 and the half of the posterior femora, and basal fourth of tibiae red; 

 calcaria pale ; head and thorax covered with a thick griseous pubes- 

 cence ; the head, except two shining lines on each side behind the ocelli, 

 and the whole of the mesonotum deeply punctured. 



Length 4 lines, alar. exp. 9| lines. 



A Scotch specimen differs from the above descrip- 

 tion (taken from a specimen taken near Plymouth by 

 Mr. Bignell) in having three-fourths of the hinder 

 femora red, calcaria darker, while the tip of the abdomen 

 wants the steel-blue tinge. 



It is about the same size and has the same colora- 

 tion as gonagra, but it has the antennae shorter, and, 

 if anything, thicker ; the puncturing on the head is 

 deeper, while it extends all over the mesonotum, besides 

 being much more rugged ; nor are the parapsides so 

 much dilated. 



Besides the above two examples, it has been taken 

 by Mr. Bridgman at Norwich, and it would appear to 

 be rarer than gonagra, with which it is no doubt con- 

 founded. Sweden is the only continental locality from 

 which it has been recorded. 



15. DOLERUS LIOGASTER. 



Dolerus liogaster, Thorns., Hymen. Scand., i, 286, 15 ; Cam. 



E. M. M., xvi, 249 ; Andre, Species, 

 i, 270 ; Cat., 34*, 35. 



Black ; femora, apex of tibiae and cerci red ; head deeply punctured 

 all over, mesonotum also punctured, but the puncturing is not so
