himself, and Dr. Horn, who transferred both species to Asida, 

 therefore changed the later one, which belongs to the present group, 

 to lecontei; but the name is not preoccupied in Euschides, a genus 

 which can never be legitimately united with Pelecyphonis, and still 

 less appropriately with Asida or Glyptasida, to which latter genus the 

 original costipennis is here assigned; so I have restored LeConte's 

 name, believing that the aphorism "once a synonym, always a 

 synonym" is unreasonable and consequently untenable. It is 

 stated by Horn under lecontei (Rev. Ten., p. 286), that some stout 

 females have a third discal costa, but his figure, which is evidently 

 drawn from a male, has the costa very prominently displayed, and, 

 moreover, the description of costipennis by LeConte, which is 

 evidently based upon the male, alludes to the third ridge as one of 

 its most conspicuous distinguishing features. The published size of 

 costipennis is apparently greater than that of any of the somewhat 

 incongruous examples in my cabinet. The description of costi- 

 pennis in the table in taken from the original by LeConte, with a 

 few additions inferable from the Hornian figure alluded to. Com- 

 pressus, of Horn, was not really described, the only written words 

 being that "the thorax and elytra are much more smooth [than in 

 costipennis] and the costee of the elytra represented by very faint 

 longitudinal ridges,," but, as a figure is given of the male which 

 may be assumed to be passably accurate, I have derived most of 

 the characters of the above description from this figure. As the 

 lustre of the upper surface is not mentioned by Dr. Horn, it is 

 assumed to be subopaque as in costipennis, otherwise so striking a 

 character as appears in the polished surface of neutralis would in 

 all probability have been mentioned. The male of neutralis differs 

 however very strikingly in its shorter and broader outline from that 

 of the male compressus, as portrayed on the plate. 



Group IV- -Type puncticollis Lee. 



This group is more northern than any other, inhabiting the 

 regions from the Columbia River Valley to northwestern Utah. 

 So far as known at present it is composed of but few rare species, of 

 very distinct habitus and distinguished from any others of the genus 

 by having visible pubescence, very short generally and perhaps only 

 distinct on the posterior parts of the elytra, but sometimes becoming
