74 The Ottawa Naturalist. [July 



15. Anoplius n. sp. ? Two specimens sent some years ago to 



Dr. Fox were stated to be a new species (?) near biguttatus. 



16. Anoplius scelestus, Cress. A purplish-black species with 



smoky wings (not so dark as those of No. 13); 4 females 2 males. 



17. Anoplius luctuosus, Cress. Closely resembles the pre- 



ceding but has paler wings; 7 females, 4 males. 



18. Anoplius hyacinthus, Cress. With bluish or purplish 



reflections; 3 females, 2 males. 



19. Anoplius angustatus, Cress. A purplish, dark-winged 



insect, of which only one male has been taken. 



20. Anoplius cylindricus. Cress. This is a smaller and slender 



species represented by 3 males. 



21. Anoplius virginiensis. Cress. A somewhat common 



slender species; 6 males. 



22. Anoplius americanus, Beauv. This insect has the first 



and second segments of abdomen red; 1 female. 



23. Anoplius tenebrosus. Cress. Appears to be a common 



species but males seem rare; 6 females. 



24. Anoplius marginatus. Say. An abundant and pretty 



species with an orange or red band on the second segment of 

 abdomen. It reseinbles No. 22, but has the third submarginal 

 cell distinctly petiolate instead of inerely narrowed toward the 

 marginal; 12 females and 1 male. 



25. Anoplius parvus, Cress. ? A specimen received from 



Guignard is labelled as the male of this species determined by 

 Provancher. It is, however, a female and does not agree very 

 well with Cresson's description, except in size. 



26. Anoplius n.sp. Two speciinens sent to Dr. Fox were so de- 



termined by him. One male also yet in my collection. 



Subfamily VI. — Ccropalince. 



27. Ceropales bipunctata, Say. This is a large handsome 



species with very long hind legs, the femora of which are con- 

 spicuou-sly red. One year it was abundant in the Beaver 

 Meadow (Hull) on the flowers of Spiraea, but since then I have 

 only taken one male. 



28. Ceropales fraterna, Smith. A smaller species which is 



gaily banded and spotted with yellow. It is abundant and varies 

 greatly in size. It has been reared from the nests of Anoplius 

 liictnosiis. C. minima, Prov. described from one of Guignard's 

 specimens is evidently only one of the small males, and one of 

 my females is not much larger; 3 males and 7 feinales. 



29. Ceropales Robinsoni, Cress. One female received from 



Guignard, determined by Provancher as his C. superba. It is 

 a very fine insect; thorax and head black with yellow markings 

 and silvery pubescence; abdomen and legs red. 



Family XXVIII.— Vespidae. 



Subfamily I. — Vespince. 



30. Vespa diabolic a, Sauss. This is our commonest yellow- 



jacket and constructs its nests even attached to houses or in 

 barns, etc.; 9 females, 7 workers and 6 males.
