AMERICAN COLEOPTERA. 105 



The last ventral of the male is emarginate at tip, in the female simple. 

 The two elytral spots may coalesce and form a continuous vitta. 

 Occurs from Pennsylvania to Texas. 



H. fuscipeiinis Guer. — Form of pulchella, color yellow, elytra piceous or 

 black. Length .18 — .20 inch; 4.5 — 5 mm. 



The elytra are a little more densely punctured than in pulchella 

 and the pubescence somewhat more abundant. The under side is 

 usually entirely yellow, but a specimen in Dr. Leconte's cabinet 

 has the under side and legs entirely piceous, also two spots ou the 

 thorax. While it differs so decidedly in color I am unwilling to 

 consider it distinct. 



Occurs from Pennsylvania to Texas. Females only seen. 



H. tlioraciea Guer. — Broadly oval, nearly as broad as long, black, thorax 

 and antennse yellow. Thorax as in pulchella. Elytra not densely punctured. 

 Body beneath and legs black. Abdomen sparsely, rather coarsely punctate. 

 Femora piceous, tibiae and tarsi paler. Length .10 — .14 inch; 2.5 — 3.5 mm. 



The last ventral of the male is emarginate. 



Occurs from Canada to Georgia. 



CYPIION Payk. 



This genus is so very closely allied to Helodes as to have been 

 united with it by nearly all authors excepting the more recent. 

 Possessing all the generic characters of Helodes, Ctjplion differs in 

 the form of the labial palpi in which the last joint arises irom the 

 end and not from the side of the preceding. As extended com- 

 parisons are already given of the genera any further repetition here 

 is unnecessary. 



The species are not numerous but present difficulties in their study 

 from the flexibility of many of the usual specific characters. The 

 following table will be found of considerable assistance while many 

 of the difficulties will be noticed under the species themselves. 



Joints 2 — 3 of antennse short, their conjoined length usually less than that of 

 the fourth. 

 Thorax in front arcuate, prolonged slightly over the head, the margin re- 

 flexed. Joints 2 — 3 equal to four I'Obustus. 



Thorax truncate in front, not prolonged nor reflexed. 

 Form oblong, subparallel. 



Joint three very short, shorter than second rtificollis. 



Joint three as long as the second. 



Sides of thorax explanate brevicollis. 



Sides of thorax not explanate exiguns. 



Form oval, moderately robust, margin of thorax not explanate. 



Entirely piceous, form regularly oval obscurns. 



Elytra with large discal spot red, form slightly oblong couciiiuus.
