ENTOMOLOGICAL SECTION. IX 



On p. 73 ]Mr. Bates seems to have doubts as to the position of 

 Polpochila. The difficuhy seems capable of sohition by accepting 

 as groups (or whatever else they may be called) those aggregations 

 of genera with male tarsi dilated and (1) biseriately squamose, or 

 (2) spongy pubescent, and (3) those with undilated male tarsi with 

 few or no squamules. While it is inferentially stated here that I 

 have suggested too many subdivisions I am reminded on p. 75 that 

 I have not made quite enough. 



Evarthrus constrictus Bates, p. 80. This name is preoccupied in 

 the genus and in the series with bisetose labial palpi. 



Blechrus glabratus DufU., p. 192. This Eurojiean species is quoted 

 from California. That the nigrinus Mann., is a Blechrus is undoubted, 

 as LeConte had a type from Mannerheim. It is highly probable that 

 the nigrinus is glabratus. I am not aware that Metabletus occui's in 

 California, but it is known from British Columbia, etc. 



On p. 220 Mr. Bates intimates that I consider Loxopeza majiiscula 

 Chd., a synonym of L. grandis Hentz (not Hald.). All my publica- 

 tions have been quite to the contrary. 



The Diseoderus mentioned on j). 27(3, as number 10, had been de- 

 scribed by me as rohustus. 



With page 256 of this volume the supplementary part begins, in 

 which we find introduced the species collected by Mr. Morrison. On 

 going over these latter it will be observed that, with extremely few 

 exceptions, all had been described from our territory. 



It seems worthy of sjiecial note that Scaphinotus mexicanus is the 

 only Cychride described or recorded, while in California species of 

 the subgenus Brennus are numerous. Arizona has not, to my 

 knowledge, furnished even a specimen of Cychride, while the adjacent 

 region of NeAV Mexico furnishes Scaphinotm Snmvii Lee, and north- 

 ward in Colorado we find only S. elevatus. 



The occurrence of a species of Carabus is remarkable. In Calo- 

 soma the fauna of Mexico is unexpectedly less rich than our own, 

 twenty being enumerated from Mexico and twenty-six with us. 

 Three are common to the two regions: scrutator, Sayi (armatum Lap.) 

 and peregrinator (carbonatum Lee.) while another, angulatum, is ad- 

 mitted to our lists with doubt.
