spots white. Abdomen dull testaceous, a broad black band on back, 

 and a whitish transverse line at the base. Legs testaceous ; coxae black, 

 broadly lined with white at sides and below ; hinder tarsi and apex of

 extended, the marks on pleurae are larger and clear 

 white, antennge paler, coxse almost wholly white, and 

 legs reddish without any black on them. 



Rare. Rannoch in June.

Tenthredopsis nigriceps, Cam., Tr. Ent. Soc., 1881, 569. 



Dark rufescent ; antennae, head below the hinder ocellus, prothorax 

 beneath, mesopleura behind, metathorax, the greater part of the four 

 anterior coxae, and all the trochanters deep black; scutellum, two spots 

 behind, and cenchri yellow. The front tibiae are paler than the rest of 

 the legs ; base of the middle femora and the greater part of the posterior 

 femora and coxae suffused with black ; hinder knees black ; posterior 

 tarsi fuscous. Head and thorax covered with a close fuscous pubes- 

 cence ; sutures of mesonotum and parapsides black ; labrum dirty 

 white; palpi dark testaceous; cerci and apex of abdomen blackish. 

 Antennae attenuated at the apex, longer than the abdomen; the 

 third joint distinctly longer than fourth ; spurs on hind legs not 

 reaching to middle of metatarsus. Wings hyaline ; costa pale, except 

 before stigma, where it is fuscous; tegulae deep black. 



Length nearly 4f lines. 



The dark rufescent colour of body, and the black 

 head and pleurae, readily separate this species from all 

 the luteous species of Tenthredopsis. 



Seemingly rare. Salen, Mull ; June.
