Station 14 and No. 2100, M. C. Z., Florissant, Col. (No. 9065, S. H. 

 Scudder coll.). 



Type in the Amer. Mus. Nat. Hist. 



The arrangement of the large umbilicate punctures on the thorax 

 of this species is more regularly transverse than in recent forms and 

 the antennae more distinctly clavate than in the majority of living 

 species, but otherwise this seems to be quite a typical representative 

 of the group. 



Eurytoma sequax, sp. nov. (Fig. 16.) 



Male. Length 3.75 mm. Represented by a poorly preserved specimen, 

 but so characteristic that it is undoubtedly an Eurytoma or a Decatoma. The 

 body is black, with a small brownish abdomen. The legs, wings, and antennae

are not preserved. One might perhaps associate it with the preceding species, 

 but the large thoracic punctures are less closely placed and show no tendency 

 to assume a transverse arrangement.
