A comment as to the generic differences is unnecessary, but 

 there are two more specimens, and 9 , which were discovered 

 in Franklin County, Pa., by my friend, H. Ulke, who kindly 

 loaned them to me a year ago; they are in his cabinet, and may 

 bring these genera still nearer together. 



Rhexidius intermedius n. sp. 



Uniformly brown. Length of $ 1.5 mm.; $ 1.66 mm. 



$ . Head as transverse as in Oropus, somewhat punctulate. Antennae, 

 without the last joint, as long as the width of the head, the last joint as 

 long as the first and second together. Eyes very much smaller than in 

 Oropus; occiput perpendicularly declining toward the neck in an angu- 

 lated line from the sides to the middle of the base. Prothorax little wider 

 than the head with a twice interrupted median sulcus and a straight trans- 

 verse sulcus, which is triangularly dilated in the middle, ending in pubes- 

 cent foveae laterally situated inside of a slightly ovate depression, the base 

 strongly punctured, the disc slightly uneven, impunctate; no crenulation 

 or a spine at the sides. Elytra as in Oropus. Abdomen at the base in 

 the middle depressed, the depression divided by a short carina; the bor- 

 ders of the first visible segment divergent; the first three visible segments 

 equal, one-quarter of their width long, fourth and fifth shorter; ventrals 

 nearly equal in length.

NOTES ON ARKANSAS LEPIDOPTERA. 



By R. R. ROWLEY, Fort Smith, Ark. 



Five hundred miles to the southwest of Curryville, Mo., where 

 the writer has spent half a score of years in the study of Ento- 

 mology and Geology of a most interesting region, is the " Bor- 

 der City," Fort Smith, Ark. A residence here since the middle 

 of September has given him but limited opportunity to niter into 

 the study of nature, but he could not, if he wished, close his eyes 

 on the fairy-like creatures that flit from blossom to blossom in this 

 city of flowers. The first finds. were two splendid larvae of that 

 magnificent moth, Citheroniaregalis, on a persirnmon tree, whirr, 

 from indications, a number of other caterpillars had been feeding; 

 t\vo larvae of Eacles imperialis on maple; two of Ccratomia
