Discocubital cell without maculae ; discocubital vein never angularly 

 broken or appendiculate ; radial vein once or twice bent or angularly 

 broken ; nervellus broken usually below the middle ; claws pectinate. 



Generic type. — E. viarginatus Jur. (Brauns, monotypical). 



The genus Eremotylus as proposed by Forster included in 

 a general way the Ophionini outside of the two genera 

 Ophion (under which many entomologists even as late as 

 1875 included Thyreodon and what is now known as Athyreo- 

 don) and Etiicospilus. This genus was proposed in a key 

 and the characters given were : 



' ' Wings without areola ; discocubital vein not angularly broken ; 

 cubital cross vein straight, with the cubital vein uniting in a very 

 pointed angle, the latter running from the head of the angle to the tip 

 of wing; discocubital cell without dark colored spots." 



Thomson evidently did not know of this genus, or did not 

 consider it valid — as no species had been designated — for he 

 does not mention it, but proposes Allocainptus as a subgenus 

 of Enicospilus and practically equivalent to Forster' s Eremo- 

 tylus. He separates his subgenus from Enicospilus by the 

 absence of maculae, and the radius being twice bent. The 

 characters given are : 



" Wings without membranaceous maculae but the base of the radius 

 strongly bent, nervulus and nervellus well antefurcal, metathorax with 

 rudimentary angular area below, broadly excavated behind, narrowed 

 transversely; mesosternum granulose-punctate, emarginate behind, 

 foveae below the punctured speculum impressed." 



In 1889 Brauns revised this group of insects, restricting 

 Eremotylus and Allocamptus but retaining both and separat- 

 ing them by the character of the radius, this being once bent
