AKT. 10 GALL-INHABITING CYNIPID WASPS- — WELD 109 



Types.— C?ii. No. 27223, U.S.N.M. Type and 39 paratypes. 

 Paratypes in American Museum, Field, Stanford, Harvard, Cali- 

 fornia Academy, and Philadelphia Academy. 



Host. — Que reus kelJoggii. 



Gall (fig. 27). — Cells in the peripheral layer of wood just under 

 the normal bark of vigorous shoots 2 cm. or less in diameter. Sin- 

 gle cells measure 3 mm. by 1 mm., the long axis parallel with long 

 axis of twig, the exit holes .7 nun. in diameter. If several cells lie 

 close together their shape is somewhat distorted and a slight swell- 

 ing may be visible on surface. 



Hahifaf. — The type material was collected at Placerville, Calif., 

 May 7, 1918, by Mr. Frank B. Herbert ; adults emerging May 21-27 

 and June 7, 1918 (Hopkins U. S. No. 13687^/^ and 15008^). The 

 writer collected galls at Los Gatos, in Palo Colorado canyon in the 

 Santa Lucia range, and in the Sequoia National Park near Colony- 

 Mill. 



The same sort of cells were noted in the twigs oi Q. ayiifolia at 

 Boulevard, Pasadena, Soledad, Monterey, Los Gatos, Berkeley, and 

 Santa Rosa ; and in twigs of Q. wislisenii at Idyllwild, Camp Baldy, 

 and Santa Margarita. 



Genus SAPHONECRUS Dalla Torre and Kieflfer 



No species of this genus has hitherto been described from the 

 Philippines. As the known species of this genus are guests in Cjmi- 

 pid galls on oak, the finding of these guests makes it certain that 

 such galls occur in the islands but none has as yet been reported. 



The only described species of the genus from the United States is 

 Saphonecrus gemmariae (Ashmead) from Florida. It was de- 

 scribed from male bred from gall of CaUirhytls genimarla (Ash- 

 mead) and the type seems to be lost. 



A key is given below to the three species here described. 



1. Areolet absent serratus Weld. 



Areolet present 2. 



2. Kadial cell three times as long as broad. Median groove evi- 



dent posteriorly areolatus Weld. 



Radial cell twice as long as broad. No median brevis Weld. 



SAPHONECRUS BREVIS. new species 



Female. — Vertex, eyes, tips of mandibles and part of occiput 

 black, rest of head honey-yellow, darker in some individuals than in 

 others. Sides of pronotum lighter yellow, median dorsal area 

 black. Pectus black, the mesopleura more or less infuscated, show- 

 ing much variation in different individuals. Metapleura, propo- 

 deum, mesonotum, and abdomen black. Parts of coxae black, fem- 

 ora more or less infuscated dorsally, other parts of legs yellow.
