110 TENTHREDOPSIS FLAVOMACULATA. 



9. TENTHREDOPSIS FLAVOMACULATA. 

 PI. XVII, fig. 4, Saw. 



Tenthredopsis flavomaculatus, Cam., Tr. Ent. Soc., 1881, 567. 



Black, sliming, pilose ; labrum, clypeus, mandibles, orbits, a longish 

 spot behind the eyes, edge of pronotum, scutellar spots, sometimes 

 a few minute spots on mesonotum, a broad band on base of abdomen, 

 and an irregular spot on coxae bright yellow. Antennae pitchy ; edge of 

 second, the whole of third, fourth, fifth, and side of sixth abdominal 

 segment bright testaceous red. Legs bright testaceous ; coxse for greater 

 part and base (sometimes a line above) of hinder femora black ; hinder 

 tarsi more or less fuscous. Wings hyaline ; costa and stigma fuscous, 

 the latter white at base. 



The $ is similarly coloured to the ? , save that the abdomen has only 

 faint indications of the testaceous colour on the middle segments and 

 beneath ; the antennae, if anything, are lighter coloured on lower side, 

 the hinder femora are entirely black, and the tibiae and tarsi pitchy. 

 The last segment above bears two deep depressions, and the yellow line 

 on base is scarcely visible. 



Length 4 lines. 



Very similar to pidiceps, but shorter and broader ; 

 the antennae shorter, head wider, head and thorax 

 more shining, and the band on the base of abdomen 

 much wider. The saw is very different. Sometimes 

 the red abdominal segments have an indistinct black 

 line in the middle. 



Not common. Mull, Rannoch, Devonshire (E. 

 Parfitt). 



10. TENTHREDOPSIS PICTICEPS. 

 PI. XVII, fig. 5, Saw. 



Tenthredopsis picticeps, Cam., Tr. Ent. Soc., 1881, 568. 



Black ; labrum, clypeus, orbits of eyes, a line on pronotum, scutellar 

 spots, the third to sixth segments of abdomen all round, and legs bright 

 red ; coxae black, largely white behind ; trochanters white ; hinder femora 

 black at the base; posterior tarsi fuscous at apex. Wings hyaline; 

 tegulse fuscous. Antennae longish, pale beneath. 



Length 5 lines. 



Allied to ornata, but it has the incision in clypeus 

 not so deep, the eyes are marked with yellow all 

 round, antenna longer and thinner, with the third 

 joint not so long in proportion to the fourth, and the
