298 AMERICAN PACHYBRACHYS (cOLEOPTERa) 



luctuosus. Identity established with reasonable certainty 



from type. 

 albescens. A type from the Suffrian Collection shows this 



to be the same as hivittatus Say. 

 pallidipennis. Identity established from type. 

 1858. LeConte — Proc. Acad. Nat. Soc. Phila., p. 84 — describes 



livens and caelatus. 

 1861. LeConte — Proc. Acad. Nat. Sci. Phila., p. 357 — describes 

 analis. 



1873. Crotch— Proc. Acad. Nat. Sci. Phila., p. 32— describes 

 xanti. 



1874. Crotch— Trans. Am. Ent. Soc, V, pp. 78-79— describes 

 donneri and circumcinctus. Crotch's types are in the Le- 

 Conte Collection. 



1880. LeConte— Trans. Am. Ent. Soc, VIII, p. 205-209— 

 makes the first attempt at a tabulation of our species. 

 Only 29 are thus treated, the remaining 20 or more being 

 listed at the end as too indefinite for tabulation. The fol- 

 lowing new species are made known: 



striatus { = pallidipemiis Suffr.), virgatus, dubiosus, cruentus, 

 lustrans, renidens { = umbraculatus Suffr.), subvittatus, 

 iurhidus and hrevicollis. 



1880. Jacoby — Biologia Centr.-Amer., Coleoptera, VI, Part I, 

 p. 72 — describes laticolUs from Mexico. Of this species, first 

 recognized by Bowditch from Brownsville, Tex., I have seen 

 typical examples, sent me by Mr. Gahan. 



1889. Jacoby — Biol. Centr.-Amer., Coleop., Part VI, Suppl., 

 pp. 136 to 151 — describes from Mexico — thoracicus, marmo- 

 ratus, immaculatus, and sonorensis. Thoracicus is at once 

 recognizable from Jacoby 's figure; the other identifications 

 are due to Bowditch. 



1909. Bowditch— Canadian Entomologist, XLI, pp. 237-244, 

 285-292, 312-324— describes a large number of North 

 American and a few Mexican species. The following are 

 those from our territory, listed in order of description: 



brunneus jacohyi minor 



wickhami mellitus lodingi 



discoideus coloradensis marginipennis 



marginatus densus punctatus
