Dr. G. H. Horn published (Tr. Am. Ent. Soc., VII, p. 41) a few 

 remarks concerning the synonymy of Batyle in its comprehensive 

 scope, but they are apparently based upon a very hasty and super- 

 ficial survey. This is indicated at least by the assignment of Eriphus 

 coccineicollis Hald., as a synonym of ignicollis; it is in no way related 

 to Batyle but is a synonym of Phymatodes amcenus Say. The synony- 

 my given under Batyle suturalis is erroneous, except in the case of 

 miniatitm Germ., and therefore cannot be adopted. 



Batyleoma n. gen. 



The species of this genus have a different facies from those of 

 Batyle, due to their peculiar scheme of ornamentation, sculpture 

 and vestiture; they are moderately numerous. The type is the 

 Callidium suturale of Say (miniatitm Germ.), rather abundant from 

 Pennsylvania westward and southward to Iowa and Mississippi. 

 In a large series at hand there is only one example having the black 

 sutural vitta described by Say, the upper surface being red through- 

 out normally. From the upper Missouri Valley to Colorado occurs 

 another form, allied to suturalis but somewhat larger on the aver- 

 age, more elongate, rather more convex and invariably having a 

 deep black sutural vitta beginning at about basal fourth or fifth 

 and often greatly expanded at apex to the margins, sometimes in 

 nearly apical half of the elytra; this was described under the name 

 Eriphus pearsalli by Bland (Pr. Ent. Soc. Phila., 1862, p. 6) and is 

 a perfectly valid species, as shown by the large series before me 

 from Colorado, kindly communicated by Mr. Frost. Rutilans Lee., 

 (Journ. Acad. Phila., ser. 2, II, p. 18) from Santa Fe, New Mexico, 

 might at first glance be thought to be the same as pearsalli, but we 

 infer from the description that the elytra are black only behind the 

 middle. This never occurs in pearsalli, for the vitta in that species 

 is never abbreviated anteriorly; it is virtually certain therefore 

 that rutilans Lee., is also a distinct species. 



Ruber Lee., (Eriphus?, Pr. Acad. Phila., 1858, p. 82) and cylin- 

 drella Csy., (Batyle, Ann. N. Y. Acad. Sci., VII, p. 587) are more 

 elongate and cylindric species, with longer legs and form a feebly 

 demarcated separate group of the genus, in which the elytra appar-
