of new species of TenthredinidcB, §-c. 395 



yellow, the tibite dusky behind ; wings fiisco-hyaline, the 

 nerviu-es black. Abdomen closely punctured, the four 

 basal segments most strongly so. 



This species very closely resembles the Pimpla cBthiops 

 of Europe, but I have never seen an example of that 

 insect Avith pale intermediate tarsi: this is the principal 

 distinction. 



Genus Thyreodon, Brulle. 

 1. Thr/reodon purpwascens. 



Female. — Length 13 lines. Obscure blue-black, with 

 bright purple tints, particularly brilhant on the mesothorax 

 and abdomen ; the antennre yellow, with two or three of 

 the basal joints black. The head closely punctured. The 

 mesothorax closely punctured and with two impressed lines 

 in the centre, which run from the anterior margin and 

 converge at the middle of the disk, the slightly impressed 

 single channel running backward to the scutellum ; the 

 scutellum and metathorax both coarsely rugose, the latter 

 having a deep central longitudinal channel ; the wings 

 dark fiiscous, and with brilliant tints of violet and purple, 

 their base and apical margins dark fuscous ; the coxte and 

 trochanters purple. Abdomen smooth, shining, and having 

 bright purple tints. 



Hab. — Hiogo. 



The description given by Brulle of Thyreodon morio 

 would, to some extent, apply to this sjDCcies, but it would 

 not distinguish the morio of Fabricius, the type of which 

 is in the Banksian Collection, now deposited in the British 

 Museum. That insect is nine lines in length, is black, 

 has the face variegated with yellow ; a spot on the man- 

 dibles, the scape in front, and the anterior legs, also yellow ; 

 the antennfe orange-yellow ; wings dark fuscous and with 

 violet iridescence.

 1. Anomalon fiavifrons. 

 Female. — Length 5 lines. Head and thorax black; 

 legs and abdomen reddish-yellow, with black markings. 

 Head : the face, mandibles and cheeks yellow, as well as 

 the scape in fi'ont ; the antennas fulvous beneath and fus- 

 cous above ; a minute yellow spot at the summit of each
