Although quite well preserved, I can refer the species to Figites only 

 in the wide sense. The slender antennae seem to exclude it from the 

 Eucoilinae. 



CYNIPIDAE. 



Cynips has been twice recorded from Amber, first by Schlotheim 

 ('20) and later by Presl ('22). Menge ('56) notes the presence of the 

 family in Amber, and Gravenhorst ('35) mentions Diastrophus (Diplo- 

 lepis) from the same source. 



From Florissant I have representatives of two of the three sub- 

 families recognized by Ashmead, the Cynipinae and the Ibaliinae. 



Cynipinae. 



There are in the collection four species which I take to be true gall- 

 flies, but from lack of personal knowledge, I have left them undescribed. 

 A single specimen, however, which appears to represent a leaf gall, is 

 I think worthy of specific record. 



Andricus myricae, sp. nov. (Fig. 7.). 



Gall regularly elliptic when seen from above, 6 mm. long and 3.5 mm. wide, 

 placed next to the midrib of a leaf of either Myrica obscura Lx. or Myrica 

 drymeja (Lx.) Knowlton (M.fallax), at a point where the leaf is about 13 mm. 



broad. Curiously enough Lesquereux has 

 figured a leaf of M. fallax with gall-like 

 excrescences upon it similar to this one in 

 as*-'- -•;. his Cretaceous and Tertiary Flora ('83, pi. 



XXXII, fig. 14). 



One specimen.

It is of course impossible to be 

 definite regarding the systematic posi- 

 tion of a fossil gall, or even to be per- 

 fectly sure that the specimen is an insect gall. However, under a 

 magnification of about forty diameters the concentric arrangement of 

 tissue remaining about the periphery of the cicatrix leaves little doubt 

 that the large central ovoid area which has now flaked off the rock
