MAY, 1910. NOTES ON SOME CLERID.E WOLCOTT. 343 



distinct ; sides at basal third parallel, posteriorly very slightly broader ; 

 apices conjointly rounded; disk rather strongly convex; stri ate with 

 rows of moderately large, closely placed quadrate punctures, becoming 

 finer posteriorly and entirely obliterated at apical fifth; the lateral 

 striae slightly longer; intervals feebly convex, slightly narrower than 

 the punctures, very finely and sparsely punctate. Abdomen very 

 finely and densely punctate. Length 8 millim. 



Female. Fifth ventral segment arcuate-truncate at apex; sixth 

 very short, arcuate-truncate at apex; fifth dorsal short, truncate at 

 apex; last dorsal short, truncate at apex; angles obtusely rounded. 

 (PI. VI, figs, i, 2.) 



Differs from longicornis, to which it is nearest related, by 

 having the head densely punctate, the thorax coarsely and densely 

 punctate, the absence of ante-scutellar impression, the rows of elytral 

 punctures longer, the form of apical segments of abdomen, structure 

 of the antenna?, and the unicolorous brown elytra. From usta Lee., 

 which it also resembles, it may be separated by the much longer 

 antennae, the second and third joints of which are shorter and less 

 conical, the more densely punctate head and thorax, the elytra nar- 

 rower at base and the secondary sexual characters of the female.

Cymatodera subsimilis sp'. nov. 



Yellowish testaceous; head, thorax, and antennas slightly darker; 

 elytra shining pale yellowish, base narrowly, scutellar region broadly, 

 sutural and lateral margins and an oblique fascia at apical two-fifths 

 slightly darker, clothed with moderately short, erect, rather dense, 

 pale brownish hairs. Antennae stout, nearly half as long as body; 

 joints two to four small, each much shorter than joint five or any of 

 the remaining joints; joints three and four much narrower than joint 

 two; eleventh joint one-third longer than joint ten. Head finely, 

 not very densely punctate; eyes only moderately prominent. 

 Thorax nearly one-half longer than wide; base slightly narrower than 

 apex, rather strongly constricted subapically, more strongly com- 

 pressed behind the middle; disk finely and rather sparsely punctate ; 

 ante-scutellar impression very feeble. Elytra parallel, less than 

 twice as wide as the thorax at base; humeri distinct ; apices conjointly 

 rounded; disk feebly convex; striate with large rounded punctures 

 which become finer posteriorly but extend nearly to apex, the apices 

 somewhat scabrous; second, third, and fourth intervals broader than
