MISCELLANEOUS NOTES. 



Cicindelidse of Chile. — Seiior Eduardo Varas Arangua, an officer 

 of the Chilean Navy, whose address is casilla 1142, Valparaiso, Chile, 

 has sent me the following notes on Chilean Cicindelidse. Five species 

 only are found in this country (a statement confirmed by Dr. Walther 

 Horn's work in Genera Insectorum) as follows: 

 Cicindela trifasciata, subsp. peruviana Cast. 

 Cicindela chilensis Br. Found from Coquimbo to Valdivia, in the 



mountainous region, extending to the coast only at Concepcion 



al Sur. 

 Cicindela gormazi Reed. Southern Chile. 

 Tetracha Carolina, subsp. chilensis Cast. Northern Chile. 

 Tetracha Carolina, subsp. latreillei Cast. Northern Chile. 

 Pycnochila fallaciosa (Chev.). Southern Chile. 

 All except C. cliilciisis are of very restricted distribution. — C. W.

A Note on Cremastochilus. — Whatever may be the basis of the 

 association which subsists between beetles of this genus and ants, the 

 fact that such association is desired not only by the ants, which have 

 often been observed dragging their unresisting " captives " to their 

 nests, but is actively sought by the beetles themselves, seemed to me 

 clearly indicated by an occurrence which fell under my observation 

 this spring. 



On May 5, 1918, a warm sunny day on which nuptial flights were 

 generally prevalent, I stood on the summit of a ridge near Greenwood 

 Lake, N. J., watching the struggles of several Euphoria iiida which 

 were beset by hordes of Formica cxscctoidcs, on whose high heaped 

 home these blundering beetles floundered. Presently a Cremasto- 

 chilus appeared flying rapidly, and upon reaching the vicinity of the 

 ants' nest began circling about it in ever-diminishing circles, and 

 continually lower, until when about ten inches from the surface it 

 closed its wings and dropped on to the heap. It was immediately 

 seized by three or four ants, and without oflfering any resistance 

 suffered itself to be dragged about more or less aimlessly, but on the 

 whole upward and away from the margin of the nest. In a minute
