XVlll MONTHLY PROCEEDINGS 



wings very long reaching way beyond tip of abdomen ; abdomen small triangular, 

 compressed, with a very long peduncle, slightly bent downwards before the middle ; 

 otherwise as in lemale. 



Described from over one hundred specimens bred in March. 



On a % cynips, cUnging to the long curved peduncle, I detected a 

 curious gamasid mite but 0.2 mm. long. It was of a reddish-brown 

 color, oval, coriaceous and pubescent ; with eight remarkably long hairy 

 legs, the posterior pair being longest, and the cephalothorax separated 

 from the abdomen by a transverse suture and with the head rather 

 pointed. It evidently belongs. to the genus Sejiix and may be known as 

 Scjus ci/nipufis. 



Another curious gall, constructed on the same principle as above but 

 smaller and not projecting through the leaf, was detected the middle 

 of April. 



Cynips q. confiisa n. sp. 



Galls. — Small, globular, slightly elongate, greenish-yellow, succulent 

 galls, . attached to the principal vein on the under surface of the leaf, 

 hollow inside with a pupa-like kernel ; fly escaping by perforating a 

 hole through the upper surface of the leaf. Diameter transversely .06 ; 

 vertically .10 inch. 



(iatl-Fly. — 9 • — Length .07 inch. Black, head finely and evenly punctate ; 

 antennae reddish-yellow. 14-jointed, third joint longest, joints to eighth subequal, 

 others short and equal, terminal twice as long as penultimate; thorax rugoso- 

 punctate, parapsidal grooves distinct, two longitudinal grooves converging pos- 

 teriorly; scutellum deeply rugoso-punctate, slightly elevated posteriorly and de- 

 pressed and with a large deep fovea at base, not pubescent ; pleurae deeply aciculate ; 

 wings hyaline, veins reddish-brown, areolet nearly closed, radial area open; 

 abdomen black and highly polished, last ventral valve projecting ; legs reddish- 

 yellow, coxfe black. 



Described from 2 9 specimens bred the last of April. 



Another gall found on the under surface of the leaves, produces a 

 very roughly punctured cynips which may be known as 



Cynsps q. riigosa n. sp. 



Gdi/s. — Semispherical, greenish-yellow, smooth, hard galls, attached to 

 the under surface of the leaf, slightly contracting the leaf on the upper 

 surface, but not projecting, either flat or slightly concave ; internally 

 consisting of a hard fibrous substance in the centre of which the larva 

 is transversely placed ; fly escaping by perforating a hole through the 

 upper surfiice of the leaf. Diameter transversely .20 inch ; through or 

 vertically .08 to .10. 



Gall-Fly. — 9 . — Length .14 inch. Head and thora.x dark reddish-brown, very 

 coarsely rugoso-punctate. Head, longitudinally narrow, ocelli almost in a straight 

 line, vertex free fmm jiubescence. face covered with short whitish pubescence.
