DESCRIPTIONS OF NEW CYNIPIDAE. 



BY WILLIAM BEUTENMULLER. 



The type specimens of all the new species described in 

 this paper are in the collection of the author. 

 Andricus nionteziiiiiiis sp. nov. 



Female. — Head red or reddish-brown, eyes and ocelli black, dis- 

 tinctly and evenly rugose, and finely pubescent. Antennae 14-jointed 

 rufous, joints 3, 4, 5 and 6 slender and almost of equal length, 7 and 

 8 shorter, 9-13 considerably shorter than the preceding joints and of 

 equal size, 14 somewhat longer. Thorax almost black, evenly granu- 

 lated ; parapsidal grooves entire, fine and distinct, and running obli- 

 quely to the scutellum where they are rather widely separated ; ante- 

 rior parallel lines sharply defined and not quite extending to the middle 

 of the thorax ; lateral grooves distinct and running obliquely forward 

 to near the parapsidal grooves. Pleurae pitchy brown-black finely 

 aciculated. Scutellum almost black, somewhat rufous apicall}^ evenly 

 rugose, slightly more so than the thorax, and with two small foveae 

 at the base. Abdomen reddish-brown, darker terminally, smooth, 

 shining, second segment with short hairs basally and at the sides, 

 smooth dorsally and terminally, following segment with short hairs 

 laterally. Legs reddish-brown, posterior pair darker. Wings pale 

 yellowish hyaline, veins brown, radial area open, cubitus extending to 

 the first cross-vein, areolet large, second cross-vein prominently angu- 

 lated. Length 2-3 mm. 



Gall. — On the twig of a species of live oak {Ouercus sp.). Poly- 

 thalamous. Composed of a number of irregularly rounded bodies, 

 tightly grown together and forming a solid mass. The outer surface 

 is leather-brown, rugose with a number of fissures and cracks indicat- 

 ing the individual galls. Inside it is light wood-brown and exceed- 

 ingly hard, almost like solid oak wood, making it difficult to cut with 

 a knife. Length, 55 mm. ; width, 35 mm. 



Habilat. — Mountains in Mexico, altitude 5000 feet. 



This species has been in my collection for some years 

 past, and I do not remember from whom I obtained it, and 

 the exact locality from whence it came. All I know is that 

 it was collected in the mountains somewhere in Mexico. A 

 similar kind of gall was sent to me by Mr. Lewis H. Weld, 

 who collected the specimen at Lake Chapala, Jalisca, Mexico, 

 from the mountains at the west end of the lake, above San 

 Pedrito, in the summer of 1910. The male is not known.
