mostly black males of other species, notably variety dorsalis of 

 D. querci-lanae (Fitch). As noted heretofore, the mostly black males 

 of several species belonging to the division of this genus without 

 submarginal wing bands are so similar that they are not yet dis- 

 tinguished. This species must be reared in order to obtain males 

 that can safely be associated with the known females. 



Girault did not indicate in his privately published description of 

 1917 that D. -fiorida is a new species. It is the first record of this 

 species in the literature, however, and is therefore the original 

 description. The second description, 1920, erroneously designates 

 it as a new species. There is no question concerning the identity of 

 the forms he had at hand on the two occasions. The locality, dates, 

 and descriptions agree, and in each article this species is likened to 

 Girault's D. marylandica^ which is similar to D. f,orida. 



37. DECATOMA GRACILIS Fnllaway 



Deoatoma gracilis Fullaway, Journ. New York Ent. Soc., vol. 20, p. 280, 1912. 



Described by Fullaway from the holotype male. The type was 

 reared by Mrs. Rose Patterson Blakeman from the gall of AndHcus 

 calif ornicus (Bassett) at Stanford University and is housed in the 

 collection of that institution. It bears lot number 508, sub. 30. Dr. 

 Isabel McCracken writes me that the type locality is St. Helena, 

 Napa County, Calif. 



I have not seen this type. Doctor McCracken kindly compared 

 with it some specimens from my Kinsey material reared from AndH- 

 cus galls in California, which seemed to me to fit the description. 

 She reports that my specimens do not agree with the type. The color 

 phase of the original description indicates strongly that the type is 

 a specimen of an extreme dark form of male similar to variety dor- 

 salis (Fitch) of querci-lanac. This form of male also occurs in 

 foliatae Ashmead, foliatae var. arizonica Balduf , and in my species, 

 quinqueseptae and wiltzae. Some dark males of foliatae^ wiltzae, 

 and variety dorsalis (Fitch) are known from Andricus species. They 

 agree with gracilis Fullaway in being mostly black with legs mostly 

 yellow. Much variation in the degree of yellow on the head, pro- 

 notum, and legs, as well as on the mesonotum, occurs on the series of 

 dorsalis and dorsalis-\i^^'^ males at hand. The type of D. g^racilis 

 Fullaway is black and has only the anterior of the face, the prono- 

 tum, " except for a median V-shaped black area anteriorly," and legs, 

 except " mid and hind femora and tibiae and hind coxae outwardly 

 marked with black," lemon yellow. This color picture comes within 

 the limits of color variation in my series of the mostly black males 

 named above. Especially is the lemon yellow characteristic on this 

 black form of male. I am unable to identify D. gracilis Fullaway
