Panorpa. 63 



2. Panoepa caucasica, n. sp. (PI. IV. fig. 2). 



P. caucasica, De Selys, MS. 



Taken in Mingrelia, by M. T. Deyrolle, in 1868. 

 Two $ and three $ in De Selys' collection. 



A species with the wings strongly marked ; the sub- 

 apical fascia forms a large, irregularly oblong spot, ex- 

 tending from the costa half across the wing, and then 

 emitting two narrow curved branches to the inner mar- 

 gin. The antepenultimate and penultimate segments 

 (c?) extremely long, and very narrow at the base, and 

 very gradually and regularly dilated, the antepenultimate 

 (7th) with a distinct tubercle at the extreme base above j 

 the claws of the terminal segment very long. The whole 

 body, including the terminal segments, deep black. 



A very distinct and well-marked species. 



B. Suh-costa in the anterior ivings reaching to the 

 pterostigma. 



3. Panoepa communis, Linne. (PL IV. fig. 3). 



P. communis, Linn. Faun. Suec. p. 384 (1761), et auct. 



The commonest species in Northern and Central Europe. 



The sub-apical fascia is angulate, and usually furcate 

 on the inner margin, especially in the $ , the apical spot 

 large, and more or less broken up into smaller spots in 

 its lower portion. The third abdominal segment ( c?) is 

 scarcely produced above at its apex ; the sixth very long 

 and truncate at the apex; seventh and eighth each 

 shorter than the sixth, conical ; appendices of the ter- 

 minal segment long and cylindrical, approximating at 

 the base and apex. 



Var ? diffinis, mihi. From Belgium and Piedmont I 

 have c^ $ of an insect which I cannot separate from P. 

 communis by any certain structural characters, yet it 

 has a somewhat difl"erent aspect, being smaller (exp. alar. 

 12 lin.) than usual, and more compact; the third seg- 

 ment is, perhaps, more sensibly produced in the middle. 

 Baron de Selys Longchamps finds it with the type-form, 

 yet preserving its peculiar facies : further investigation 

 may perhaps establish its right to specific distinction. 

 An insect figured in Imhofi" and Labram^s " Insekten 

 der Schweiz," under the name of P. vulgaris, may pos- 

 sibly be the same as this.
