~90 Cynipidae. 



eyes and ocelli dark brown. Prothorax narrow; middle lobe of 

 mesonotum large, rounded in front, lateral lobes wedge-shaped ; scu- 

 tellum large, rounded in front, heart-shaped. Abdomen broad and 

 rounded at base, with a depression in the centre, rather pointed at 

 apex. Wings large, hyaline; costa and nervures black; forewings 

 clouded with a f uscous patch about 2 / 3 from the tip of wing. Legs 

 clothed with flne hairs. 



The galls are roimd or oval, fleshy, about the size of a large 

 filbert nut, containing several cavities in each gall. When they are 

 ripe, about the end of October, they are brightly tinted with red 

 and yellow, and are known in Yictoria as „Wattle apples" by the 

 children. They are formed on the flower stalk, as are also certain 

 dipterous galls, and are very plentiful on the Acacias growing back 

 from Eose Bay. Unless taken quite ripe, they are difficult to keep, 

 as the galls decay, and the larvae die in consequence.

Cynips Maideni, n. sp. 



Length of body, 2 lines. Expanse of wings, 4 lines. 



cf. Head, thorax, abdomen, coxae and base of femora black; 

 the rest of the femora, tibiae, and tarsi pale yellow in live specimens, 

 darker in old ones. 



Q. Differs in being slightly larger, with the abdomen broader, 

 and from below the first segment of a rich yellow slightly margined 

 with black on the sides. 



Antennae 13-jointed, ochreous-yellow, clothed with fine hairs; 

 lst joint cylindrical; 2nd cub-shaped; 3 — 4th, very small, funnel- 

 shaped; 5 — lOth cylindrical, broad, rounded at base, and straight 

 across at apex; in the female these joints are smaller and more 

 subovate; 11 — 13th forming an oval-shaped club; in the male the 

 5th joint is much larger than the following ones. Eyes vermilion 

 when alive, ocelli bright hyaline; head round in front, square behind. 

 Thorax broad, shining, very rugose, the corrugations running in 

 wavy lines ; middle lobe of mesothorax large ; scutellum large, shield- 

 shaped. Legs covered with fine hairs. 



I have much pleasure in dedicating this fine species to J. H. 

 Maiden, Esq., F. L. S., Curator of the Technological Museum, to 

 whom I am indebted for many specimens, and whose work among 

 our wattles is well known. This Cynips causes the small twigs and 

 branches of Acacia longifolia to swell into thick fleshy galls, often 

 several inches in circumference, and five or six inches long.
