Hetcerius brunnipennis Rand. Occurs here occasionally with a 

 medium-sized honey-yellow ant in April and May. 



H. Blanchardi Lee. Mr. Blanchard, the discoverer of this species, 

 took it and Ulster perpunctatus with the same species of ant. (Tr., 8, 

 190.) 



Echinodes aetiger Lee. This singular form has occurred variously ; in 

 South Carolina and Georgia with a pale ant. (Horn. Proc. Am. Phil. Soc, 

 13, 305.) Zimmerman found it at Columbia, South Carolina, in April, 

 with a small brown ant. (Tr., 2, 253.) And it has been taken in Haber- 

 sham County, Georgia, in the nest of a small ant under bark. (Pr., 1859, 

 3i6.) 



Cremastochihis Schaumii Lee. Dr. Horn frequently found this 

 species in ants' nests in California. (Tr., 3, 339.) 



C. Westivoodi Horn. Found in or near ants' nests in Owen's Valley, 

 California, where it is not rare. (Pr. Am. Phil. Soc, 18, 139.) 



C. a,7igtilaris Lee. This species was taken frequently in ant's nests in 

 California by Dr. Horn, who several times saw large black ants dragging 

 the beetles towards their nests. He strongly suspects the fossa; at the 

 anterior angles of the thorax and the finely punctured and perforated 

 patches under the hind angles yield a secretion grateful to the ants. This 

 species extends to Vancouver. 



C. variolosus Kirby. One specimen occurred here with ants. 



C. canaliculatus Kirby. Is the most abundant species found here ; it 

 is found from April till June with large black ants, perhaps of two species, 

 inhabiting usually under stones or other covering, but not infrequently 

 throwing up small mounds in old pastures and open ground. The nests 

 under stones rarely yield more than two beetles, but the mounds often con- 

 tain five or six at once, and with care will yield a crop every two or three 

 weeks. The beetles are found near the surface, none having been taken 

 below the plane of the base. 



As soon as it becomes warm, from the middle of April onward, this 

 species takes leave of the ants and flies away ; like the Cicitidelce it only 

 flies during the hottest sunshine and for short distances, alighting suddenly 

 on a stone or the middle of a dusty road. Its flight is low and heavy, 

 and after it lights cannot take wing again without some delay, and I have 

 seen it flying as late as August. Whether after having left, the same beetles
