242 THE CANADIAN ENTOMOLOGIST. 



with the name given is that he had before him an insect with dark legs, 

 which neither of the species mentioned nor the nondescript has, and with 

 little tendency to in any individual observed. Possibly the insect described 

 may belong to some foreign country. 



Haltica igiiita 111. — This species is so protean in colour, form and in 

 the wide range of the vegetation it affects, that it is difficult to believe all 

 the forms included under this name really belong to one species till one 

 looks for tangible structural differences. It has a very extended distribu- 

 tion, from the Hudson Bay region to Florida and Texas, and was 

 described by Dr. LeConte, from Fort Simpson, on the McKenzie river, 

 under the name incerata. It is easily separable into at least three races, 

 two of which occur here in the greatest abundance. The first is the 

 typical form, having the upper side of a brilliant golden-copper colour, 

 though individuals occur with it violet or green. It is foimd during May 

 on Azaleas growing among huckleberry. A colour variation of this 

 form is found at the same time on Kalmia, with the upper side entirely 

 green, individuals occurring of a coppery and violet colour, or with the 

 thorax violet, or coppery and the elytra greeh. The length of this form 

 is from .14 to. 17 inch; the punctuation of the elytra is comparatively 

 coarse and not very close. 



The second form is much smaller, .11 to .13 inch in length; the 

 punctuation of the elytra is finer and less distinct ; the form is less 

 elongate, and more depressed ; the colour of the upper side is either 

 green or violet, but individuals occur with all the variations of the preced- 

 ing. It appears here about the first of June and depredates on the 

 Rosacea^, seeming to have a special fondness for the wild plum, wild 

 cherry and wild strawberry. I have this variety from New Jersey, 

 Florida and Texas ; the preceding, from Wisconsin, Michigan and 

 Canada. Dr. Horn, in his Monograph of the genus, mentions a deep 

 blue race, and likewise a brown race without metallic lustre, as occurring 

 in Florida, but I have met with neither. This species is distinguished 

 from all others except chalybea and nana by the deep ante-basal groove 

 of the thorax, which extends completely across to the marginal depres- 

 sions.
