80 Mr. R. E. Turner's Notes on the Thynnidss, 



CopJiothynnus iridi2Jennis, Sm.

 1879, t. 



$ . Clypeus scarcely produced, slightly emarginate at the apex. 

 Mandibles bidentate, the outer tooth long and acute. Antenna) a 

 little shorter than the head and thorax, the third joint of the flagel- 

 lum nearly half as long again as the second. Head narrowed behind 

 the eyes, finely and shullowly punctured, a laminate prominence 

 above the base of each antennre, the front and cheeks with sparse 

 white pubescence. Eyes very slightly convergent towards the vertex, 

 the inner margin almost straight ; the posterior ocelli about twice as 

 far from the eyes as from each other, nearer to the eyes than to the 

 posterior margin of the head. Thorax rather sparsely punctured ; 

 the scutellum triangular. Median segment rounded, longer than 

 broad, longer than the mesonotum, closely and shallowly punctured. 

 Abdomen as long as the rest of the insect, fusiform, very closely 

 punctured ; with a raised curved mark on each side of segments 2-4, 

 just before the narrowlj'-depressed apical margin. Hypopygium 

 rounded at the apex and ciliate, projecting a little beyond the epipy- 

 gium. The first cubital cell is divided, much shorter than the second 

 on the cubital nervure, the third is rhomboidal, also shorter than the 

 second. 



The abdomen is less elongate than in most species of the genus 

 and the whole insect is more stoutly built. The three apical joints 

 of the maxillary palpi are very long and slender, combined half as 

 long again as the head. Otherwise as in Smith's description.

 ptera carhonaria, Sm., and Tliynnus (etliiops, Klug, in the 

 genus blunts. He may prove to be correct, the three 

 apical joints of the maxillary palpi being very long and 

 slender, especially in carhonaria, but they are not very near 

 any known species oi JElurus, and the female is unknown. 

 Thynnus anthracinus, Klug, is closely allied to Mhiops. 



Eirone mutdbilis, n. sp. 



^ . Clypeus slightly advanced, with a vertical triangular trunca- 

 tion at the apex. Head shining, shallowly punctured, the front 

 almost vertical and broad ; the antenna) slender, about half as long 

 again as the head, with a short and obscure V-shaped carina between 

 them ; the vertex long and broad, the posterior ocelli nearly twice as
