Descriptions of some new species of Insects, with observations on described speciese 
By 8. S. Hatpeman. 
CEcINDELA LEconTEI Hald. Dull cupreous, beneath green, with cupreous 
reflexions; white pubescent ; head rugulose longitudinally upon the front, and 
transversely behind; labrum white, anterior margin blackish, short, transverse, 
strongly tridentate in the middle; palpi blackish green. Prothorax minutely 
wrinkled, narrowed posteriorly, disc convex, transverse impressions and dorsal 
line profound. Elytra convex, nearly double the width of the base of the pro- 
thorax, finely and obsoletely punctured, with an irregular stria of large punc- 
tures, base greenish; lunules submarginal, distinct, and yellowish white, the 
humeral one rectilinear, and extending to one-fourth the length of the elytra, 
where it is incrassated on the inner side, touching the medial fascia, which is 
triangular, with the apex extending one third of the distance towards the suture; 
the apical lunule is bent at a right angle, and reaches the suture. 
Allied to C. rugifrons and C. scutellaris, resembling the latter in the charac- 
ter of the prothorax, and differing from the former in having the humeral lunule 
entire. 
Wisconsin, Guex. Cab. Le Conte. 
C. ancocisconensis Harris. ©‘ Urper lip 3-toothed, thorax narrowed behind. 
Bronzed blackish brown above, with white humeral and terminal lunule, and 
intermediate angular band enlarged on the margin; body beneath green, tail 
purple.”? Harris. 
Form rather slender, head tinged with metallic green, longitudinally rugulose, 
especially upon the orbits; front with distant impressed shallow punctures; 
labrum white or discolored, the margin obscure, strongly 3-toothed, with an 
obsolete tooth on each side; mandibles black, with the base white; antenne 
and palpi metallic green and blue, with white hairs. Prothorax as wide as the 
eyes, and with the scutel, minutely scabrous, anterior, posterior and dorsal lines 
well impressed with metallic green, lateral margins punctate. Elytra minutely 
punctate with blue or green impressed microscopic points, with an indistinct 
subsutural irregular line of larger distinct punctures, and one or two very short 
similar lines on the humerus. Humeral lunule curving slightly inwards poste- 
riorly, terminal lunule abruptly enlarged anteriorly, sometimes continuous with 
the marginal portion of the middle fascia, which is behind the middie of the 
elytron, extending transversely less than half the distance towards the suture, 
and bent backward and inward, terminating in an enlargement near the suture. 
Beneath and feet green, with white hairs. In the male the base of the maxil- 
lary palpi is yellow. 
New Hampshire, Dr. Harris; Philadelphia, Schafhirt; Cab. Le Conte. 
Evarturus Gravipus. Black, somewhat shining, robust and depressed, pro- 
thorax transverse, lateral margins reflexed, broadly rounded, slightly sinuate 
posteriorly, dorsal and anterior line impressed, basal angles square, with two 
well impressed longitudinal stria, the surface of this part and the posterior part 
of the dorsal line being marked with irregular waved transverse strie. Elytral 
striz well impressed, finely punctured toward the base, except the submarginal 
ocellate row, interstices slightly convex. Length 102, breadth (elytra) 4 lines. 
Var. 2. Interstices of the elytra smooth, with the punctures more distinct. 
Var. ¢. Elytra smooth, the striz and punctures indistinct. 
This species adds a group (2f,) to the five of Le Conte, given in the Journ. 
Acad. Nat. Sci. 2d ser. 2, 227, and establishes a complete paratlelism between 
the two divisions of the genus Evarthrus formed by him, the relations between 
the sections 2e and 2f, being equivalent to those between la and 1b. The cha- 
racters of group f. are: Elytrorum striis non approximatis, thorace qvadrato, 
postice utrinqve bi-impresso. |

Le Conte alluded to this species, Journ. Acad. 2d ser., 2, 223, specimens have
