NOTES ON CHRYSOMELA

Extract

Chrysomela scalaris Lec. The question asked by Dr. Hagen in the June number concerning the name of this insect, is more easy to answer than to arrive at a definite conclusion. Stal, in his monograph, did not recognise many of the genera into which Chrysomela had been divided; among them were Doryphora and Leptinotarsa. Finding that Olivier in 1807 had described a D. scalaris, and the Maj. LeConte in 1824 a Chrys. scalaris, Stal superseded the latter name by multiguttis. Recent authors are in accord in adopting many of the genera rejected by Stal, and the name originally given our species becomes valid and has been adopted by Jacoby (Biol. Cent. Am., vi, pt. i., p. 197, pl. xi., fig. 6). That the name should remain in future Calligrapha scalaris is fortunate, since we have lately received from Arizona a specimen of Calligrapha multiguttata Stal (in cab. Lec.), which is well figured in the work above cited, pl. x., fig. 5.
