it be a western species distinct from abbreviata as suggested by Van 

 Duzee ('05). 



Note 10, p. 238. — Euschistus variolarius. In a study of the 

 genus Euschistus, I noted examples of an apparent variety of variolari- 

 us having the usual black terminal ventral dot of the male, but with 

 small black dots at the sutural intersections of the abdominal mar- 

 gin as in fissilis and other species. The humeral spines are very 

 prominent in these specimens, and the lateral edge just in front of 

 the spines is concave or straight instead of being more or less con- 

 vex. This variety is represented in variolarius from H.2 and 3. 



Note 11, p. 239. — Homauius wneifrons. In this genus the gen- 

 eral aspect of the punctuation varies to a remarkable degree. The 

 surface pattern is formed by sudden changes in the density of the 

 punctures, emphasized by contrasting shades of the ground color, 

 which also varies excessively in distinctness, from sharp contrasts 

 to their almost total obliteration; but its form is nevertheless very 

 constant for each species. The differences in the median scutellar 

 pattern may be tabulated as follows : 



Median pale line of scutellum rather suddenly widening back of middle into 



a broad medio-apical stripe. 



Medio-apical stripe parallel -sided, the dark adjacent color gradually 



shading off. Length, 7-8 mm. .... geneifrons Say. 



Medio-apical stripe usually narrowing posteriorly, margined by a dark 



line. Length, 4.5-6 mm. .... grammicus Wolff. 



Median pale line gradually widening into a narrow medio-apical stripe. 



bijugis Uhl. 



Median pale line very narrow or interrupted at posterior third of scutellum, 



in front of and behind this usually very distinct, posteriorly spread 



out fanlike or broadly subtriangularand gradually darkening, to apex. 



proteus Stal, 



Proteus is readily recognized also by the deep notch in the flap 

 like anterior extension of the prosternum each side of the middle. 



Note 12, p. 242. — Ilarpalini, n. sp. This interesting carabid 

 appears to be generically and specifically new. It belongs to the 

 tribe Harpalini, but as the single specimen obtained is a female, 

 its systematic place is uncertain, and it does not seem advisable 

 to do more at present than to call attention to its striking 

 peculiarities. 



It is about the size of Harj>alu8 testaceus, but even paler than 

 that species, yet apparently perfectly matured ; the thorax has the
