when 'he flies escape fom the coenons 

 was not ascertained, bul from the posi- 

 tion they were in it is clear that a slight 

 fall in the level of the lai\e such as fol- 

 lows a change in the wind or comes nat- 

 urally in the hot sammer weather would 

 leave the cocoons on the dry sand and 

 probably the flies would escape at such a 

 tim.e. This habit of forming sand cccoons 

 is apparently unique, for there is no re- 

 cord in Europe of the ea' ly stages of this 

 genus (nor indeed of any other genus 

 forming sand cccoons), and the species 

 would doubtless repay further study. 



Spathiophora fascipcs Beck, is a Euro- 

 pean species that has been recorded in 

 North America only from one locality on 

 the shores of Lake Erie and two on Lake 

 Michigan. 



Amorostoma ma'ginata Loew, is a form 

 that is vei-y difficult to see. It lives on 

 the bare sand of the dunes of the main 

 ridge and the sandy shore line of the spit. 

 An allied species A. macidata lives in a 

 similar habitat at Pacific Grove, Califor- 

 nia. 



Fucellia ma itima Halliday is also of 

 considerable interest since it is normally a 

 sea shore form breeding in decaying sea- 

 weeds. It is abundant on the eastern 

 coast of the United States as far south as 

 Cape Hatteras and on the West coast of 

 Euro])e. While it has been found occa- 

 .sionally inland in Europe, it has only been 

 reported b^y Malloch from Waukegan, 111., 

 on Lake Michigan, and the LTnited States 

 X^ational Museum un'il now had no speci- 

 mens from any inland water. It is to be 

 noted that the sand beaches of this area a: e 

 very similar to the spit on which the spe- 

 cies was taken. 



Four specimens cf a Sapromyzid fly 

 were taken, which Dr. Aldrich informs me 

 beloiig to a new genus and new species that 

 he hopes he will be able to describe shortly.

Tlie tiger beetles C. histicollis were seen 

 occasionally on the beach in the bright sun 

 but proved difficult to catch. • On July 

 12th, 13th and lltli they were more plenti- 

 ful and many pairs were copulating. Wlien 

 disturbed they do not separate but fl^' to- 

 gether, the male, as far as could be seen, 

 carrying the female. This made the flight 

 slower and the insects more easy to cap- 

 ture. They were not seen so plentifully 

 although July 16th was apparenth^ an ideal 

 day. The species is not at all common in 

 the province and local in its distribution. 



The beetles C. ni alt i punctata were ex- 

 tremely common on the willow bushes and 

 all stages from eggs to perfect forms were 

 obtained on July 10th. Cer'^ain small 

 bushes they entirely stripped of leaves and 

 their choice of species was marked. Tliey 

 attacked mainly S<di.r lucida and <S. dis- 

 color, less frequently S. longifolia, and 

 never 8. peltita or S. Candida. In one case, 

 even when practically all the leaves of a 

 small 8. lucida were eaten, they did not at- 

 tempt to ea'^ those of an 8. Candida the 

 twigs of which were actually mixed witli 

 and touching theii- food plant. 



Tlie species Creophihis villosus was 

 found entirely in the shed where the fish 

 were cleaned and packed and was quite 

 common there. 



I'lij/Uophaga (ni.iia was not taken at 

 first, but during tlie evening of July 8'h 

 large numbers of them were flying abcut 

 and probably- a hundred or two di-opped 

 into the camp fiie. The next day tliey 

 were found on tiie spit, but not al all 

 plentifully. On the evening of the lOtli 

 they were again flying in large numbers 

 and fell into the fire. It would ai)i)eai' as 

 if they were in course of migration, frr 

 onlv a verv few were found after that date.
