our species the vertex is more or less obtusely angled. and not 

 evenly rounded as in the South American lineata with which 

 Burmeister was evidently comparing - his cana, and I believe 

 that a comparison with his type if that were possible would 

 show that this is the form he was describing. If he meant that 

 the vertex of his cana was acutely angled before it could not be 

 a Gypona as that character alone would throw it into another 

 genus. Spangberg has evidently redescribed this same species 

 as flavilineata Fitch. He describes the vertex as "subangu- 

 larly produced" which is frequently the case in this species 

 especially in the males I am unable to distinguish between 

 this form and that described by Provancher as quebecensis. The 

 latter has a slightly different aspect as it is of a deeper green, is 

 a little smaller, and the fulvous vittse are almost or quite obso- 

 lete. Provancher's species has the elytra entirely reticulated as 

 I know from the examination of a typical specimen sent me by 

 himself at the time he was publishing his Petite Faune Ent. du 

 Canada, although this character was not mentioned in either of 

 his descriptions of the species. 



286 Gypona striata Burmeister, variety. 



This form I took with the preceding from which it differs 

 in being of a clearer green color with the elytra reticulated at 

 apex only. It is smaller and darker than the typical striata as 

 found farther north and is really intermediate between these 

 two species. The typical striata Burmeister was redescribed 

 by Fitch as flavilineata. 



287. Gypona sp. 



Sanford and Sevenoaks ; two examples. This species seems 

 to have about the same distribution as cana but perhaps does 

 not extend its range quite so far north and south. It can read- 

 ily be recognized by its dark olive green color closely mottled 

 with pale and marked with two black points on the pronotum. 

 It is perhaps the olivacea of Spangberg but at present I have 

 not access to his description. 



288. . Gypona tenella Spangberg. 



Sanford and Sevenoaks. This is a neat little green species 

 having the elytral areoles without reticulations.
