TENTHREDOPSIS ORNATA. 155 



Tenthredopsis TRTSTIS (Vol. I, p. 111.) 



I cannot find that this species is described by 

 Konow in his Revision. It appears to be related to 

 his T. arrogans. The head is dilated behind the eyes, 

 the tegulae are black, the antennae about as long as 

 the abdomen, the apex of clypeus not quite transverse. 



Tenthredopsis ornata (Vol. I, p. 111). 



According to Konow there are two species of Ten- 

 thredopsis with incised clypeus allied to this, namely, 

 stigma, F. = dorsalis, Spin., = Mstrio, Klug, and 

 semirufa, Kriechbaumer (Regens. Oorresp.-Blatt., 

 1884, 15. We have, I believe, the latter species. 



T. semirufa is smaller than ornata (8 mm. as against 

 10 — 14 mm. for the latter) ; the antennae are more 

 slender, and as long as the abdomen ; the second abdo- 

 minal segment is only black in the middle, in ornata 

 entirely black ; the hind femora are broadly black at 

 the apex, in ornata only very slightly, if at all ; the 

 tibiae are black at the apex, in ornata entirely red, and 

 the coxae are broadly lined with white. The arrange- 

 ment of the white markings is the same in both species ; 

 the stigmas are white at the base ; in semirufa the 

 second recurrent nervure is received near the second 

 transverse cubital ; in both species there are two 

 black lines on the ventral surface; ornata has the wings 

 of a clearer hyaline colour. 



According to Konow, T. dorsalis, Spin, (see vol. i, 

 p. Ill), is a synonym of T. stigma, Fab., = histrio, 

 Klug, and ornata, Andre, non Lep. In my opinion 

 ornata, Lep., = excisa, Thorns. 



The examples I have seen of ornata, Lep., have no 

 black on the femora or tibiae ; but von Stein states 

 that they are often entirely or partly black (cf. W. E. 

 Z., 1884, 357).
