yellow. The variation in color of the thorax hag been indicated, 

 that at the apex of elytra is variable in extent, rarely smaller than 

 shown in the figure, but sometimes much larger. 



A s})ecimen in my cabinet from Texas has the elytra nuich more 

 coarsely ])un(!tate than usual, the thoracic piceous area small, the 

 sides and apex of abdomen yellow. This may indicate a distinct 

 species, but with a uni(pie and the recognized variation observed in 

 other species it does not seem safe to separate it under a distinct 

 name. 



H((h. — Florida, Texas, Wyoming, Kansas and perhaps New York 

 and Missouri. 



H. seiiiiruber n. sp. — Oval, outline refjiilar, fouvex, head and thorax red- 

 dish yellow, elytra piceous, the apical third or nearly half reddish yellow, beneath 

 piceous, abdomen almost entirely and legs yellow. Head moderately punctate. 

 Thora.x narrower in front, sides feebly arcuate, basal marginal line distinct, sur- 

 face sparsely, indistinctly ])unctate. Elytra moderately coarsely, closely, not 

 densely punctate ; prosternuin in great part yellow, the elevated lines entire and 

 convergent ; metasternum at sides coarsely and closely punctate, the mesocoxal 

 line joining the suture one-third from the front. Abdomen closely punctate, the 

 metacoxal arc entire, not quite reaching the first suture, the enclosed area smooth. 

 Length .08 inch, nearly; 2 mm. 



This species resembles colluris, but ditiers in the much greater ex- 

 tent of the red elytral apex and by the almost entirely reddish yel- 

 low abdomen. The e:j^tent of the red elytral apex is as great, or even 

 greater than observed in Bralki {^ha'morrhoati Lee). 



H(tb. — Florida, Texas. 



^J. piineticollis Lee. — Oval, black, rather dull, sides of thorax indefinitely 

 yellow, apex of elytra narrowly reddish. Head pi(!eous, mouth i)aler, surface 

 finely punctate. Thorax narrowed in front, sides feebly arcuate, basal marginal 

 line distin(!t, surface evidently punctate, more closely toward the sides. Elyti-a 

 more coarsely jninctured than the thora.x and moderately closely ; prothorax be- 

 neath piceous, prosternal lines entire and nearly parallel; metathorax at sides 

 coarsely not densely punctate, mesocoxal line joining the lateral suture near the 

 fr<mt. Abdomen closely punctate, the metacoxal arc entire very nearly as long 

 as the segment ; tibiiP and tarsi pale, femora more or less piceous. Length .(W — 

 .10 inch. ; 2 — 2..5 mm. 



The fifth ventral is broadly and deeply emargiuate. The first 

 ventral has a smooth median area limited each side by a narrow 

 space of fine, short pubescence. 



The last two or three segments are usually paler, .sometimes also 

 this color extends indistinctly on the sides of the other segments. 



This species is allied by general characters to collariH. The head 

 has never been observed to be yellow, nor are the sides of the thorax
