DESCRIPTIONS OF FOUR NEW ORTHOPTERA FROM MACEDONIA. 157 



The type is from Lembet, 25, vi.-4, vii., 1916 ; two paratypic 

 females were taken at the same locality in August, 1918. 



One of the females agrees in its coloration with the above described 

 male, while another female, being entirely identical with it in all the 

 morphological characters, is green with only feeble traces of the 

 typical design on the head, pronotum and elytra. This indicates that 

 the new species is variable in its coloration, like other species of the 

 genus Aeolopus, but it is very well defined in its morphological 

 characters. 



The chief specific characters of A. burri are the large and thick 

 head, the broad and obtusely truncate fastigium of the vertex, the 

 shape of pronotum and the relative shortness of elytra. The form of 

 the fastigial foveolae, as well as the position of the- false vein in the 

 discoidal area and not sulcate frontal ridge are the characters which 

 separate A. burri from A. tergestitius, Miihl. From A. strepens the 

 new species is easily distinguished by the shape of pronotum, which is 

 not unlike that in A. thalassinus, F., by the form of hind femora which 

 are short but not dilated as is the case in A. strepens, as well as by 

 the coloration of elytra which is so characteristic in A. strepens. The 

 distinctive characters of A. burri from A. thalassinus, to which the new 

 species is most closely related, are also numerous and leave no doubt as to 

 their specific value; the principal distinctions between these two 

 species are in the shape of the head, and especially of the fastigium, in 

 the relative length of the prozona and metazona of pronotum, as well 

 as that of hind femora and elytra. All this proves that the species is 

 undoubtedly new, and I have much pleasure in dedicating it to my friend, 

 Dr. Malcolm Burr, who has done so much to increase our knowledge 

 of Orthoptera in general. 



I should propose the following key for identification of the four 

 European species of the genus Aeolopus : 



1. (6) Temporal foveolas elongato-trapezoidal. Frontal ridge not sulcate. 

 Intercalate vein in the discoidal field approaching apically to the radial vein. 



2. (3) Pronotum distinctly tectiform, without a constriction ; its disc only 

 slightly narrowed forwards. Elytra in the most part black, with two narrow 

 transverse fasciae. Metazona one half again as long as prozona. Hind femora 

 short and much dilated basally, with the apex attenuate ; hind tibia? distinctly 

 shorter than femora. Elytra extending distinctly beyond the hind knees. 



A. strepens, Latr. 



3. (2) Pronotum decidedly selliform, with a distinct constriction ; its disc 

 distinctly narrowed forwards. 



4. (5) Head thick, shorter than the pronotum ; face distinctly reclinate. 

 Fastigium of the vertex scarcely longer than broad with the apex decidedly 

 truncate. Elytra only reaching the hind knees. Hind femora short, though not 

 dilated. Hind tibiae distinctly shorter than femora. A. burri, Uvar. 



5. (4) Head narrow, shorter than the pronotum ; face distinctly reclinate. 

 Fastigium of vertex distinctly longer than broad, with the apex acute. Elytra 

 extending far beyond the hind knees. Hind femora narrow and elongate ; hind 

 tibiae scarcely shorter than femora. A. thalassinus, F. 



6. (1) Temporal foveolae elongato-triangular. Frontal ridge sulcate. Inter- 

 calate vein in the discoidal area distant equally from the radial and ulnar vein 

 along ils whole course. A. tergestinus, Miihl. 



Ancistrtjra, gen. no v. (Phaneropterinae). 



$ . Fastigium of the vertex short, obtuse. Antennte very long, setaceous. 

 Pronotum selliform ; transverse sulcus distinctly behind the middle ; hind 

 margin rather raised, but not inflated, truncate. Elytra free, inflated, oval, 

 coriaceous ; the inner margin not angulate ; plicate vein thick, callous, irregular ;.
