in tliree oblique series. The elytra are entirely red with a narrow 

 apical margin, and sub-scutellar trapezoidal spot black. Legs entirely 

 black. Length .22 inch ; 5.5 mm. 

 Occurs in California and Oregon. 



H. Gloveri, Horn, Trans. Am. Ent. Soc. 1870, p. 134. 



Form robust as in areuatus. Thorax with two entire strite. Elytra 

 with three entire dorsal and a short sutural stria. Subhumeral stria 

 obsolete replaced by a few punctures, humeral appendix short, moderate- 

 ly impressed. Prosternal lobe acutely produced in front. Hind tibite 

 biseriately spiuulose. Legs piceous. Color variable. Length .22-. 20 

 inch; 6.5 mm. 



From all the species of the group this may be once known by the very 

 acute prosternal lobe. In the typical specimen the color is entirely black, 

 while a variety in the cabinet of Dr. Leconte has the elytra colored as in 

 hiplagiatus, but with less distinctness of definition between the black and 

 red portions. 



Kansas and Indian Territory. 



H. instratus, Lee. Col. Kansas, 1859, p. 7. 



Similar in form to seUatiis. Thorax with lateral strire both entire and 

 with no apical intermediate stria3. Elytra with three entire dorsal strife, 

 a rudiment of a fourth and moderately long sutural, subhumeral stria 

 wanting or with merely a faint trace of a short humeral appendix. Elytra 

 colored as in sellatus. Legs colored as in areuatus. Hind tibiie biseri- 

 ately spinulose. Length .22 i«ch ; 5.5 mm. 



His species is very closely allied to hiplagiahts, Lee, but differs by its 

 more robust form, its more distinctly fimbriate thorax, and by the outer 

 row of spinules of the hind tibi;e being composed of spinules very closely 

 approximated. In the specimen before me there is a very short appen- 

 dicular stria under the liumeral prominence very feebly impressed, which 

 never exists in any hijtlagiatus that I have seen. From Uloi'eri it 

 differs in having the tip of the prosternal lobe broadly rounded and not 

 acute. 



Occurs in Kansas.

 1854, p. 552, pi. 9, fig. 119. 



There is no trace whatever of subhumeral stria or humeral appendix 

 in any specimens before me. Thei-e are three entire dorsal striae and 

 rarely a trace of the fourth at base. The sutural frequently extends one- 

 half to base, usually much shorter. Thorax sparsely fimbriate, hind 

 tibiie distantly spinulose, legs black or piceous. Length .20 inc|i ; 

 5 mm. 



Abundantly distributed from the ]\Iiddle States to Georgia, and west- 

 ward to Kansas.
