7. Apathus elatus Fab. Not rare. 



Andrenidce. 



8. Andrena hilar is Smith. A few only, on flowers. 



9. M hirticeps Smith. n tr 



10. 1- miser abilis Cress. Abundant. 



1 1 . Hal ictus coriasccus Smith. A few only. 

 \2. M iigatns 'Sidiy. Common. 



13. " discus Smith. Common. 



14. II albitarsis Cress. Common. 



15. M Icevipennis. This name does not appear in the Check List, 



but the insect so named by Mr. B. is remarkably abundant. 

 There are numerous other species of Andrena and Halictus 

 not yet determined, some of them being very plentiful. 



16. CoIIetcs tJioracica Smith. Not common. 



17. Osinia lignicola Prov. Not common. 



18. Megachile brevis Say. Abundant, resting very often in the burrows 



made by Buprestis lauta Lee. 



19. 'I mendica Cress. Also very common. 



20. Ceratina tejonensis Cress. Rare. 



Vespidce. 



21. Vcspa maculata Fab. Only too numerous, building enormous nests 



of more than a foot in diameter. I suppose it is equally 

 abundant in the eastern provinces. 



22. n media OXw. Common. The suspended nests of this wasp are 



very noticeable in early spring. 



23. M sp. A species which Mr. Brodie could not determine. It is 



of the size of V. media. 



24. M sp. Another Vespa which may be a new species. It is exceed- 



ingly abundant and remarkably savage. The sting, too, is 

 more than ordinarily painful. Its nests are subterranean, and 

 the racoons evidently consider the comb a favorite morsel. 

 These animals probably destroy the greater number of nests 

 before the close of the season, and if it were not for this 

 check, I am afraid the insects would soon become an intoler- 

 able pest. Being so common here, I shall be pleased to send 

 a long series to any Hynienopterisl who will send me a box.
