 about the intermediates ? 



Marolia (Dircaea) Iloimbergii, Mann. 



Three examples of this pretty little species from Queen Charlotte 

 Island, British Columbia, are before me, which agree absolutely with Man- 

 nerheim's description. Dr. Leconte described Ilyptihis ftiimitians irom 

 Oregon in words so similar to Mannerheim's, that his description is entirely 

 applicable to these examples, allowing for a little variation in the colouring 

 of the tibiee. As Dr. Leconte suggested, his species is probably the same 

 as Mannerheim's, and a comparison of types seems scarcely necessary. 

 (Bui. Mosc, 1852, 347 j Proc. Acad. Phil., 1859, 284.) Mannerheim's 

 type was a unique taken at Sitkha. 



Cteniopns nnirrayi, Lee. 



Andrhnus is proposed by Mr. Casey for this and four other forms 

 described by him as species, namely, brunneiis, concoior, nigrescens and 

 convergens. Lately came to hand one ^ and five ^ examples belonging 

 to this genus, said to have been taken at one place near Jacksonville, 

 Florida, which I would have referred without hesitation to imcn-ayi, had 

 it not been for Mr. Casey's paper. Using the characters he employs in 

 the separation of his species, there should be three as valid as any of his, 

 and neither of them murrayi nor Mr. Casey's species. One $ and its 

 assumed 9 a-re near brunneus, but not quite ; two $ 's approximate con- 

 color, but there are points of difference ; while the other two do not quite 

 agree with the description of murrayi. Without discussing details, with 

 these insects in hand, and a careful study of Mr. Casey's de.-^criptions, the 

 conclusion reached is that at least three of his species, and the three 

 which it would otherwise be necessary to create, are all one, and that 

 murrayi. The Cistelidae is one of the degredational families in which 

 great latitude must be allowed for individual structural variation, other- 

 wise there will be an excessive and artificial multiplication of species. 



Apion — A species occurs here very abundantly in June on Vaccinium 

 stamineum which seems to be undescribed, apparently belonging in section 

 4 of Smith's Synopsis ; it may be known by its slender beak, shorter in 

 the $ , antennae inserted near the base, with the first joint short and 

 strongly clavate, the second one half its length, but not more slender ; 

 by the thorax short, scarcely narrowed anteriorly, closely moderately punc- 

 tured, and with a circular impression at base more or less obvious, the
