synonym of micans, but Knwert makes it a distinct variety, though the 

 characters he gives are very unsatisfactory and appear, indeed, to be 

 derived partly from the exudation with which his examples were 

 covered. 



I have before nie three specimens from Merv (Hauser) sent to 

 the late Mr. Fry as H. viicans, var. snbcostahis, by Eeitter. They are 

 extremely similar to the Armenian example I have above accepted as 

 being micans Fald., and, relying on these, I should be inclined to con- 

 clude that subrostatus is merely a synonym. In view of the doubts as 

 to the determination of my specimens this amounts to very little. 



I have been able to examine the aedeagus of one of these Merv 

 examples and find it to be peculiar, inasmuch as the lateral lobes and 

 median lobe are less flattened than usual, resembling, indeed, three 

 fingers, or toes ; the lateral lobes are a little the longer and rather 

 blunt. The distinction from the aedeagus of E. besicanus is sufiicieutly 

 well marked to certify the two as species. 



Besides these examples I have seen four from Mesopotamia 

 (Millingen) which are so near to the Armenian insect that I think 

 it well not to separate them on the authority of such scanty material, 

 the chief distinction being that they are a little smaller and paler, and 

 the thoracic grooves are a little less deep. An examination of the 

 aedeagus shows these specimens to be immature, but the organ is 

 sufiicieutly different from that of besicanus to make it certain that 

 these two are distinct species, the aedeagus being more like that of 

 Triclielojjliorus. It is not concordant with that of the Merv form, but 

 as it is nearer thereto, and the material so scanty, and the general 

 characters so close, I will not rely on it. 



Two specimens from Persia from different sources are pretty 

 certainly conspecific with the Mesopotamian examples, and a single 

 example from Arabia (Hedjaz, Millingen) is also probably of this 

 species. 



My review of this inadequate material may be summarized by 

 saying that E. micans may be a variable species, but it is probable 

 also that more than one are mixed under the name. I regret that I 

 have not seen any Austrian example. 



Trichelophorus Kuwert. 



True epipleuron small, false epipleuron large. Supra-pleural area rather 

 broad and parallel. Setosity and pubescence of under-surface and hind feet 

 well developed. Pronotum not hooded, hind angles obtuse.
