26 LE CONTE.— COLEOPTERA OF THE 



Clytus irroratus, niger, pube subtili cinerea irroratus, thorace latitudine haud breviore, lateribus bene 



rotundatis, rude punctato, dorso longitudinaliter subelevato, tuberculis paucis transversis notato, utrin- 



que subplanato, elytris fusco-testaceis, subtilius dense rugosis, plagis nigricantibus, lineolisque angulatis 



cinereo-pubescentibus variegatis, ad apicem singulatini acuminatis femoribus apice bispinosis. Long. 



•5— -75. 



Texas, Mr. Haldeman. Resembles in color and markings C. nauticus, but 



differs very much by the thorax being regularly rounded on the sides, and the 



femora with two terminal spines as in C. 1 u s c u s , &c. The scutel is covered with 



dense white pubescence, divided by a black line. The cinereous angulated lines of the 



elytra are very indistinct. The antennse are thickened externally. 



Tetraopes discoideus, niger, undique cinereo-pubescens et nigro-pilosus, tborace lateribus parum 

 sinuatis, medio subito sed baud alte elevato, guttis 4 nigerrimis notato, apiee et basi coccineo, elytris 

 basi lateribus et ramo ad medium laterali obliquo coccineis, mox pone ramo macula utrinque niger- 

 rima notatis ; antennis nigris haud annulatis. Long. -32. 



Llano Estacado, Capt. Pope. Remarkably distinct from all other species by the 

 black head. It is more nearly allied toT. umbonatus Lee. than any other, and 

 its marking may be conceived to be derived from the design of that species by 

 extending the black over the greater part of the thorax, and enlarging the anterior 

 black blotch of the elytra so that it unites with the posterior one, as in some varieties 

 ofT. canteriator. 



Euryscopa aeneipennis, feneo-nigra, undique dense cinereo-pubescens, thorace latitudine haud 

 breviore, lateribus rectis, confertim punctato, linea dorsali obsoleta, elytris viridieeneis glabris, fortiter 

 seriatim punctatis, seriebus versus basin introrsum confusis, lobis humeralibus majusculis pubescenti- 

 bus ; antennarum articulo 3io 4to paulo minore. Long. -26 — -33. . 



Llano Estacado, Capt. Pope. Belongs to Lacordaire's Division IV. (Col. Phytoph. 



2, 506.) 



Euryscopa vittata, nigra, subtus dense cinereo-pubescens, capite dense, thorace ad latera modice 

 pubescentibus, hoc latitudine breviore, lateribus subrotundatis, medio parce subtiliter lateribus distincte 

 punctato, elytris seriatim punctatis vitta lata rubra a humero longe ultra medium extensa. Long. -29. 



One male, Llano Estacado, Capt. Pope. Seems related to the Mexican Eu. 

 Pilatei and scapularis Lac, but differs by the longer elytral vitta: it covers en- 

 tirely the lobe of the epipleurae, but leaves the humeral callus black. 



Doryphora R o g e r s i i , rotundata valde convexa, nigro-cyanea, thorace minus dense punctato, subtilius in 



medio, lateribus rotundatis, postice subparallelis, elytris auruntiacis, seriatim punctatis, seriebus per 



paria approximatis, externis confusis, macula magna humerali, alterisque pluribus parvis nigris. 



Long. -32—47. 



Platte River, Nebraska: Llano Estacado, Capt. Pope. Related to D. trimacu- 



lata, but apart from the markings of the elytra, it differs by the sides of the thorax 



being nearly parallel posteriorly, so that the base is not at all narrowed as in that 



species. The spots on the elytra are variable in size, and the two middle ones are 



sometimes confluent. They are placed : on each, two small ones near the base, and
