when the flies escape from the cocoons 

 was not ascertained, but from the posi- 

 tion they were in it is clear that a slight 

 fall in the level of the lake such as fol- 

 lows a change in tlie wind or comes nat- 

 urall}' in the hot summer weather would 

 leave the cocoons on the dry sand and 

 probably the flies would escape at such a 

 time. This -habit of forming sand cocoons 

 is apparently unique, for there is no re- 

 cord in Europe of the early stages of this 

 genus (nor indeed of any other genus 

 forming sand cocoons), and the species 

 would doubtless repay further study. 



Spathiophora fascipes 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 nuvginata Loew, is a form 

 that is very 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. maculata 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 

 Europe. While it has been found occa- 

 sionally inland in Europe, it has only been 

 reported by Malloch from Waukegan, 111., 

 on Lake Michigan, and the Ignited States 

 National Museum until now had no speci- 

 mens from any inland water. It is to be 

 noted that the sand beaches of this area are 

 very similar to the spit on which the spe- 

 cies was taken. 



Four specimens of a Sapromyzid fly 

 were taken, which Dr. Aldrich informs me 

 belong to a new genus and new species that 

 he hopes he will be able to describe shortly. 



Order Coleoptera. 



The Coleoptera were kindly identified 

 for me by Mr. J. B. Wallis, of Winnipeg, 

 as follows : 



Family Cicindelidae, Cicindela duode- 

 cimguttata Dej. var. hucolica, Casey; Ci- 

 cindela hirticolis Say; Family Cambidae, 

 Bemhidion ca inula Cho. ; Family Omo- 

 phronidae, Omophion icrsalatum Say; 

 Family Dytiscidae, Ilyhius angusiior Gyll ; 

 Family Gyrinidae, Gyrinus maculiventris 



Lee; Family Silphidae, Silpha tritubercu- 

 lata Kby ; Family Staphylinidae. Creophi- 

 lus maxillosHS var. villosus Grav ; Family 

 Histeridae, 8op inns fratenius Say; Fa- 

 mily Phalaeridae, Olih. us semiatriatus (?) 

 Lee; Family Coccinellidae, Voccinella pei- 

 plexa Muls (?) trifasciata L; Coccinella 

 transversoguttata Fald ; Family Scaraba- 

 eidae, Phyllophaga anxia Lee (dubia 

 Smith); Family Chrysomelidae, Callig.a- 

 pJia multipunctata Saj' ; Galerucella nym- 

 phaeae L; Tre hahda netidicollis Lee 

 (larva of this or closelv related species 

 A. 0. Boviry, U. S. Nat. Mus.) ; Family 

 Cureulionidae, Hylobius confiisus Kby. 



The tiger beetles C. hisUcollis were seen 

 occasionally on the beach in the bright sun 

 but proved difficult to catch. On July 

 12th, 18th and 14th they were more plenti- 

 ful and many pairs were copulating. When 

 disturbed they do not separate but fly 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 IGth was apparently an ideal 

 day. The species is not at all common in 

 tlie province and local in its distribution. 



The beetles C. rmUtipunctata were ex- 

 tremely common on tlie willow bushes and 

 all stages from eggs to perfect forms were 

 obtained on July 10th. Certain small 

 bushes they entirely stripped of leaves and 

 their choice of species was marked. They 

 attacked mainly Salix lucida and S. dis- 

 color, less frequently 8. lovgifolia, and 

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

 even when piactically all the leaves of a 

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

 tempt to ea"^ those of an S. Candida the 

 twigs of which were actually mixed with 

 and touching their food plant. 



The species Creophilus villosus was 

 found entirely in the shed where the fish 

 were cleaned and packed and was (juite 

 common there. 



Phyllophaga anxia was not taken at 

 first, but during the evening of July 8'h 

 large numbers of them were flying about 

 and probably a hundred or two dropped 

 into the camp fi: e. The next day they 

 were found on the spit, but uot at all 

 plentifully. On the evening of the 10th 

 they were again flying in large nuinl^ers 

 and fell into the fire. It would appeal- as 

 if they were in course of migration, for 

 only a very few were found after that date.
