have an additional j)in-]abel "Collect. Sonier 1870", and both were 

 placed at the drawer-label "steininalis Burni." (in Dr. Brauer's 

 hand) when I saw them. The following description is compiled 

 from notes made from the types at Halle and at Vienna ; their 

 proper specific name is, I believe, coniractum Rambur, of which also 

 I have studied the type (see the index, post) at Oxford. 



% (types of Burmeister). Vertex brown or dark bluish, frons luteon.s or olive 

 becoming bluish above, clypeus luteous or pale greenish, lips yellowish, median 

 labial lobe brown or black. 



Thorax luteous with brown, ill-defined stripes as follows: a short antehumeral 

 not reaching the base of the front wing, a humeral, one at the (obsolete) iirst 

 lateral suture, one on the second lateral suture : latero-ventral metathoracic carina 

 or a stripe thereon brown, as is a stripe on the mid-dorsal carina in the Halle type. 



Legs luteous. knees brown, or blackish with the first femora yellowish infe- 

 riorly. Third tibiae with 7-9 exterior (anterior), 11-13 interior (posterior) spines. 



Abdomen luteous, the carinas and transverse bands at the bases and apices of 

 the segments brown, which on 5 and 6 reduce the luteous to the middle third of 

 the segment and on 7-10 cause its almost entire disappearance (Halle type) ; or 

 pruinose above, luteous below, with black at the intersegmental articulations 

 having one-third the extent of the luteous of each respective segment (Vienna 

 type). 



Appendages of the usual form, very pale yellow, the denticles alone black, tips 

 of the superiors broken off; or blackish except at the tip. 



Genitalia of the second abdominal segment essentially similar to the figure I 

 have given for cnpensis (Proc. U. S. Nat. Mus. xvi, p. 584, f. 3, 1893). 



Wings : reticulation uniformly brown in the teneral Halle type, blackish-brown 

 throughout in the (older) Vienna males. Pterostigma yellowish, or dark brown. 

 Meml)ranule dark brown, slightly whitish at base. Arculus a little more remote 

 than the second anteuodal. But one row of cells between the subnodal sector 

 and the supplementary sector next below. 



Front wings: 13-15 antenodals, 10-12 postnodals, one hypertrigonal (2 on left 

 side of Halle %, ), internal triangle 3-celled, discoidal triangle with one cross-vein, 

 three posttriangular rows. 



Hind wings: 11-13 antenodals. 11-12 postnodals, no hypertrigonals, triangle 

 free, no internal triangle, two posttriangular rows increasing, sectors of the tri- 

 angle almost united, or very slightly separated at origins. 



Total length 42 mm., abdomen 29 (these two measurements are from the Vienna 

 type, as abdominal segments 7-9 are shrunken in that at Halle). Hind wing 

 31.5-32. Pterostigma 3.5-3. 



In the foregoing description wherever alternative statements in- 

 dicated by the word " or " are made, the statement before the " or " 

 applies to the Halle type, that after the " or " to the Vienna type. 

 The latter is evidently an older individual.
