gray beetles breed with like color but do not cross, tho they 

 have every appearance of being the same. They feed almost 

 exclusively on the young growth and eat it entirely to the rib 

 of the leaflets. There were a few seen last year but not to the 

 extent to cause any special treatment for them." 



The species is represented in the collection of the U. S. National 

 Museum by the following material : Eagle Harbor, Lake Superior, 

 June (Hubbard & Schwarz); Eagle River, Lake Superior (Hub- 

 bard & Schwarz); Marquette, Michigan, June and July (Hub- 

 bard & Schwarz); Euclid, Minnesota, June 13, 1896 (R. P. 

 Currie); Dakota (C. V. Riley, Coll.); Nebraska (H. Ulke); El- 

 more, South Dakota, June and July (J. L. Webb) ; Mandan, North 

 Dakota (F. E. Cobb). 



Dr. Paul Standley, Botanist of the Smithsonian Institution, 

 has informed me that Caragana is a genus of trees found in southern 

 Europe and Asia, which has been introduced into the United 

 States for ornamental purposes and is sometimes known as the 

 Pea Tree. 



A NEW GENUS OF CHALCID-WASP BELONGING TO THE FAMILY 



EULOPHIDAE. 



BY A. B. GAHAN, U. S. Bureau of Entomology. 



The new genus described below is remarkable among Eulophids 

 because of the fact that it is practically wingless. This character 

 at once distinguishes it from all other Eulophid genera known 

 to the writer, with the exception of Melittobia. The latter genus 

 is apterous or subapterous in the male sex only, while the new 

 genus is wingless in the female. The male is unknown. The 

 new genus is apparently not closely related to Melittobia since 

 the antennal pedicel is longer, there are three distinct ring-joints 

 and the funicle joints are more elongate; the scutellum is without 

 any longitudinal grooves, the pronotum is shorter, the propodeum 

 shorter and sculptured, while the general habitus of the insect is 

 quite different, it being much more compact in appearance. 



The classification of the Eulophidae into subfamilies and tribes 

 is largely based on wing venation which makes it extremely 

 difficult to place this wingless form with any degree of accuracy. 

 It appears however to belong to the subfamily Elachertinae, 

 and to be very closely related to the genus Miotropis as represented 

 by M. clisiocampae Ashmead. In fact, except for the undeveloped 

 wings and a somewhat shorter propodeum it might well be con- 

 sidered to belong to Miotropis. The new form is readily rec- 

 ognized, however, and seems to be deserving of a new generic 

 name which I have accordingly given it below.
