290 Professor Williston on ihe 



2. Teucholahis annulata, n. sp. (PI. X.^ fig. 63_, wiaj^.) 

 ^ , 5 . Front black ; palpi brown ; rostrum and first joint of 

 the antennae yellow ; flagellum brown or black. Mesonotum. 

 shining, with three broad, more or less confluent, shining, deep 

 broad stripes, the middle one not reaching the suture, the lateral 

 ones not extending far in front of it ; elsewhere the mesoi^otum, 

 like the scutellum and anterior part of the metanotum, is light 

 yellow. Pleurae dark yellow or brown ; when seen obliquely, with 

 a silvery sheen. Posterior part o£ metanotum brown. Abdomen 

 yellow, with a broad brown band on the anterior part of each 

 segment. Legs yellow ; all the femora brown at the tip, and with 

 a brownish ring beyond the middle ; all the tibise and the first 

 three tarsal joints brown at the tip, the last two joints of the tarsi 

 black. Wings hyaline ; the stigma and a cloud at the end of the 

 costa — sometimes obsolete — brown. Length 7-8 mm. 



Twelve specimens. In one female the abdomen is black, 

 with a narrow yellow posterior margin to the segments ; 

 in others brown, with a broader yellow border. The 

 nenration is very much like thafc of T. complexa ; both the 

 second and third veins are curved less, and the second 

 vein extends further towards the tip of the wing. 



Elliptera. 

 Schiner, Wien. Ent. Monatschr., vii., 222, 1863. 



1. ? Elliptera, sp. (PI. X., figs. 64, wing ; 64a, genitalia.) 



$ . Head brownish, or brownish-yellow, including rostrum and 

 palpi. Antennae yellow, the first two joints red. Mesonotum 

 brownish grey, with four narrow, brownish stripes ; humeri and 

 sides of prothorax light yellow. Pleurae yellow, obscurely brown- 

 ish in places. Abdomen light luteous yellow. Legs yellow ; the 

 tip o£ femora, tibiae, and the distal joints of the tarsi brownish. 

 Wings hyaline ; stigma faintly brown. Length 5 mm. 



One specimen. The present species can hardly be a 

 true Elliptera, because the anterior veins do not show 

 the approximation characteristic of that genus, but it 

 seems to agree in all other respects. The antennae are 

 sixteen-jointed, the joints oval in shape ; the thorax is 

 gently convex, the pronotum small, the abdomen is 

 elongate, etc. The neuration is shown in the figure. 

 There are no spurs to the tibiae.
