294 BULLETIN 14 5, UNITED STATES NATIONAL MUSEUM 



DISTRIBUTION 



Material has been examined from various localities in the following 



States : 



District of Columbia, Illinois, Indiana, Iowa, Kansas, Maryland, Michigan, 

 Missouri, New Jersey, New York, Ohio, Pennsylvania, South Carolina, 

 Virginia, West Virginia and Wisconsin. It has also been recorded in 

 the literature from Louisiana and Mississippi, but these records may 

 refer to the subspecies celticola. 



Variations. — The color is quite constant, but the pubescence may be 

 more or less abraded. The median depressions on the pronotum vary 

 more or less in depth, but still preserve the form of two depressions 

 united by a groove. Length 4 to 6 millimeters. 



Host. — This species has been reared a number of times from dead 

 branches of hackberry {Oeltis occiclentalis Linnaeus). Lugger (1884) 

 records it as breeding in dogwood (Comus florida Linnaeus), but 

 this is probably an error of identification, either of the insect or the 

 host. 



This species was first described by LeConte (1859) under the name 

 of subfasciatus, but since this name was preoccupied by Gory (1841) 

 for a species of the same genus from Brazil, Saunders (1871) re- 

 named it lecontei. 



102a. AGRILUS LECONTEI CELTICOLA, new subspecies 



This subspecies differs from the typical form in having the pubes- 

 cent designs on the elytra usually more distinct, and the male with 

 the tarsal claws similar on the anterior feet, both claws being cleft 

 near the tip, and the two teeth about equal in length, whereas in 

 the typical form the claws are dissimilar on the anterior feet; one 

 claw is cleft near the tip and the teeth nearly equal in length, the 

 opposite claw is cleft near the middle, and the inner tooth broader 

 and distinctly shorter than the outer one. Male genitalia similar 

 to lecontei Saunders. 



Length, 3-6 mm. ; width, 0.9-1.75 mm.
