COLEOPTERA OF KANSAS 



jointed antennJB and simple ungues. The rough sculpture and short sparse pubes- 

 cence o-ive the insect very much the appearance of an Ochodceus. 



D. rudis feiTugineo-fuscus, oblougus, parum uitidus, pilis brevibus minus subtilibus, albidis minus 

 dense vestitus, capite punctate, liemihexagono, clypeo antice latius emarginato, thorace convexo 

 antrorsum angustato, lateribus valde rotundatis, dense punctate, elytris rugose punctatis, sutura 

 costisque solitis tribus parum elevatis, pygidio eonfertim punctate. Long. -30. 



Two specimens from the black hills: Dr. W. A. Hammond. The punctures are 

 large and not deep. The body beneath is more shining, and less densely punctured.

O. SCIltellaris, apterus, niger, thorace cataphracto valde inaequali, lateribus rotundatis, elytris 

 seriatim minus distincte punctatis, transversim cailatis, interstitiis subquadratis, subaequaliter 

 parum elevatis. Long. -6 — "65. Tab. I, fig. 4.

Fi'om Platte river to Santa Fe. Other nearly allied species found in Texas are 

 described by me in the place above cited ; from all of them, however, it may be 

 distinguished by the assemblage of characters here given. 



CA]\'THO]¥ ILLIGER. 



C praticola, subovatus, ater opacus, supra subtilius licet evidenter granulatus, clyijeo 6-dentato, 

 dentibus duobus mediis obtusis, reliquis latis modiee prominnlis, thorace brevi convexo, lateribus 

 valde rotundatis, elytris capite thoraceque vix longioribus, basi late emarginatis, lateribus et apice 

 rotundatis, planiusculis versus scutellum paulo impressis, striis parum distinctis ; thorace subtus 

 versus angulura anticum tubcrculo minuto marginali instrueto, pro receptione pedum parum exca- 

 vato, pygidio convexiusculo, parce subtiliter granulato. Long. 27 — '37. 



Kansas and New Mexico. Eesembles C. nigricornis, but the form is less abbre- 

 viated, the lateral teeth of the clypeus are more prominent, the elytra are less 

 sparsely granulate, and the pygidium is more finely granulate, not impressed or 

 carinate towards the base. 



For the purpose of enabling the relations between the species of Cantlion inha- 

 biting the United States to be understood, as well as of providing names for several 

 nondescript species, I add the following synoptic table : — 



A. Prothorax pleuris linea transversa a eosis proeedente obsoleta vel nulla. 



a. Prothorax pleuris raargine versus angulum anticum tuberculo minuto subinterrnpto. 



* Clypeo rotundato, bidentato ; (species magna;). 



rotundatus supra granulatus, oculis latiusculis vigilans. 



rotundatus, oculis angustissimis ; 



supra evidenter granulatus Isevis. 



obsolete granulatus chalcites. 



** Clypeo 6-dentato; (species minores). 

 I Pygidio rude granulato, basi plus minus carinato ; 

 elypei dentibus omnibus magnis ; 

 oblongo-rotuudatus, supra rude granulatus ebenus. 



rotundatus, supra subtilius granulatus depressipennis. 



elypei dentibus lateralibus minus prominulis ; 

 breviter rotundatus, supra subtiliter, elytris parcius granulatus nigricornis.
