^RT. 10 GALL-INHABITING CYNIPID WASPS WELD 85 



ANDRICUS STROPUS Ashmead 



The types of this species were reared in March. The writer has 

 collected galls like the types at Daytona, St. Petersburg, Clear- 

 water, Marianna, and Ocala, Fla., on Q. chapmani and at Palestine, 

 Tex., on Q. steUata, but has never reared adults. 



ANDRICUS TOUMEYI, new species 



Female. — Reel, slightly infuscated on anterior and lateral lines, 

 on sternum and ventral j)art of abdomen in these recently trans- 

 formed specimens cut from galls, no doubt still darker in those 

 emerging normally. Head coriaceous, with radiating striae about 

 mouth, face, and occiput pubescent; from above transverse, as broad 

 as thorax, cheeks broadened behind eyes; from in front facial area 

 higher than broad, malar space three-eighths ej^e, antenna 13-seg- 

 mented. lengths as (scape) 14: 8 : U: 13: 12: 11 : 10: 10:9:9:9: 8: 15. 

 Sides of pronotum with parallel ridges, pubescent. Mesoscutum 

 coriaceous with scattered setigerous punctures, the hairs short and 

 white, not hiding sculpture, parapsidal grooves deep, smooth, percur- 

 rent, wider behind, no median. Scutellum rugose with two deep 

 smooth pear-shaped pits at base. Carinae on propodeum straight 

 and parallel, enclosed area broader than high. Mesopleura aciculate 

 excei^t for smooth hind margin. Hind tibia longer than tarsus, 

 claws with a weak tooth. Wing hyaline, short-pubescent, ciliate, 

 veins yellowish, first abscissa of radius angled, areolet incomplete, 

 cubitus indistinct. Abdomen longer than head and thorax, length 

 to height to width as 120 : 98 : 80, lengths of tergites along dorsal 

 curvature as 104 : IG : 5 : 5 : 4 : 12, second with small pubescent areas at 

 base, ventral valves hidden, ventral spine slender, in side view 7 

 times as long as broad. Using Avidth of head as a base the length 

 of mesonotum ratio is 1.2, antenna 2.0, ovipositor 2.0, wing 3.8. 

 Length 2.7-3.3 mm. Average of eight, 3.0 mm. 



Named for Professor Toumey, to whom also the host oak is dedi- 

 cated. Closely related to Andi^icus howertoni Bassett, from which it 

 may be separated by the aciculate mesopleura and the more scattered 

 pubescence on the mesoscutum. 



Tyiie.—Q^i. No. 27216, U.S.N.M. Type and 3 paratypes. Para- 

 tyi)es in American Museum, Field, and Stanford. 



Host. — Quercus tounieyi. 



Gall (Hg. 20). — A sessile, egg-shaped and somewhat one-sided 

 stem swelling, representing a much shortened lateral branch Avhich 

 seldom continues beyond the gall, densely covered with small leaves. 

 It measures up to 15 mm. long by 10 mm. in diameter, is covered 

 witli bark of normal thickness, its single rather small cell is placed
