The last four forms mentioned are, as treated by Horn, only 
color varieties of one species, but whether that species is typical 
canella or not, is questionable. It should probably be known as 
aterrima (Oliv.). The P. sellatus Horn and P. opacicollis Lec. are 
both, in my opinion, valid species. 
lala dan ( ). P. opacicollis Lec.—Gainesville; taken by Watson in July 
by beating along the edge of a cypress swamp. Since I first recorded this 
form from Florida (1923, 31) I have taken several additional examples in In- 
diana, and a careful study of them shows that they are undoubtedly distinct 
from any of the forms listed as varieties of canella. 
XXIV. Labidomera Chevrolet. 
Large oval, strongly convex species (8-12 mm.) having the 
elytra yellow with large black markings; front femora of male 
strongly toothed. Adults on milkweed. This and the genera 
up to XXIX possess the characters mentioned under Colaspis 
except that the front coxae are transverse and the third tarsal 
joint usually entire. (Subfamily Chrysomelinae.) 
*118 (15639). L. clivicollis (Kirby.)—Dunedin, Feb.-Mch.; taken by beat- 
ing dead leaves and bunches of the slender climbing milkweed, Metastelma 
scoparium Nutt. (Bl., 1919). The only definite record for the State. 
XXV. Leptinotarsa Stal. 
Oval, strongly convex species of medium size (6-11 mm.) hav- 
ing the elytra dull yellow, with double rows of confluent punc- 
tures, the suture and five narrow stripes on each black; front 
femora unarmed. 
119 (15648). L. decemlineata (Say).—Northern tier of counties from 
Pensacola to Jacksonville; on the Gulf coast as far south as Panama City 
(Wat.). Known as the “Colorado potato beetle.” Food plants, potato, horse 
nettle and other Solanacea. No definite Florida record in any of the lit- 
erature at hand. 
XXVI. Calligrapha Erichson. 
Oval, convex species of medium size (6-9 mm.), having the 
elytra yellow with brown stripes or small bronzed spots, and sides 
of thorax not thickened, third tarsal joint entire. Both larvae 
and adults feed on foliage of various species of shrubs and herbs. 
*120 (15665). C. similis Rog—Northern two-thirds of the State. At 
hand from Gainesville, Lakeland and Dunedin. Frequent about Dunedin, 
Dec.-Mch., on flowers of various Composite. 
121 (15667). C. cephalanthi Sz., 1878, 366.—Types from Ft. Capron, 
L. Harney and Tampa. Enterprise (C. & L.). Ft. Myers, Apr. 26 (Davis 
Coll.) (Bl., 1923). Labelle (Kn.). Occurs only on the button-bush, 
Cephalanthus occidentalis L.
