species of Galeodes of similar appearance, and perhaps poison 

 ous, which would account for the fear of the natives. 



Mr. B. P. Mann stated that he had decapitated some living 

 Caloptenus femur-rubrum to utilize the remains as food for 

 tortoises, and that he had observed that while the bodies were 

 upon the ground in natural posture they exhibited apparently 

 normal powers of sanitation. Some ants having seized the 

 tarsi of the decapitated locusts, the latter sprang away with 

 vigor and alighted upon their feet again. The experiment 

 was repeated several times with the same and with different 

 individuals. When the locusts were confined so that they 

 could not jump, they kicked vigorously and flung the ants 

 away from them. Locusts confined but not mutilated did 

 likewise for a time, .but after awhile yielded to the ants, and 

 allowed themselves to be bitten without resistance.

COLEOPTERA ON BLACK LOCUST (Robinia pseudacacia). 



BY E. A. SCHWARZ. 



Early in May, Mr. H. Ulke found a rare and interesting 

 Cucujid beetle, Ino reclusa, on dead branches and trunks of 

 black locust trees, and as I was desirous of finding this 

 vSpecies myself, I made during May and June a rather 

 careful investigation of a few small trees which had recently 

 died from the combined influence of fire and insect attacks. A 

 few of the most promising pieces of the trunks and larger 

 branches were carried home by me, and an astonishing num 

 ber of specimens bred from them. The following list includes 

 the species that have been bred up to the middle of June, as 

 well as those which were cut from the trees in the field. All 

 come from a small locality in the vicinity of Washington 

 known among the resident entomologists under the name of 

 "red-bug meadow," and where, besides the Acarid which 

 furnished the name, a host of rare insects of all orders can be 

 found throughout the whole year.
