AUTUMN NUMBER 19 
Indiana and Sanford, Fla. At hand from Sanford, Pahoka, Palmdale and 
Dunedin, Mch.-Apr., from the muck and grass roots about the margins of 
cypress swamps. But little more than half the size of typical pennsylvanica, 
and probably a distinct species. 
165 (15896). D. quinquevittata (Say.)—Schwarz in his Florida list 
records D. punctigera Lec. as “not rare.” That name is made a synonym of 
quinquevittata by Horn (1889, 314). No other mention from the State. 
166 ( ). D. fumata Lec.—According to Scheffer (1919) the D. cren- 
icollis (Say.) of Horn (1889) is this species. Under the latter name it is 
mentioned by Schwarz (Ms.) as occurring at Jacksonville. 
*167 (15898). D. caroliniana (Fabr.).—Enterprise and Capron (Sz. Ms.). 
Lakeland, May 8 (Davis Coll.). At hand from L. Wales, Palmdale and 
Dunedin. Swept in some numbers, Mch. 28, from the flowers of a tall St. 
Johnswort at Palmdale. Rare at Dunedin on fetter-bush. 
*168 (15901). D. glabrata (Fabr.)—Ormond, on oak (Bl. 1902); Dun- 
edin Mch. 9, one specimen at each place. Gainesville, abundant on bull- 
thistle, Apr.; riddling the foliage of pig-weed, Amaranthus, May (Doz.). 
These the only State records. 
169 (15902). D. abbreviata Melsh.—Recorded from numerous stations 
in the northern half of the State. Gainesville, sweeping low herbage 
Feb. 26 (Doz.); on golden-rod, Sept. (Wat.); these, in part at least, Oedi- 
onychis petaurista (Fabr.). Scheffer (Ms.) doubts the occurrence of the 
true abbreviata in Florida, but a specimen taken at Lake City, Apr. 18, is 
in the Gainesville collection. 
*170 (15902a). D. leptolineata Blatch., 1917, 143—Types from Dunedin; 
also taken at Lakeland and Istokpoga. Frequent on ferns in dense ham- 
mocks and cypress marshes; also hibernating beneath cover along the bor- 
ders of ponds. Described as a variety of abbreviata but evidently a dis- 
tinct species. 
171 (15906). D. triangularis (Say).—Gainesville, Apr. 15; sweeping low 
foliage along a moist hammock edge, and hibernating under old logs (Doz.). 
The only State record. 
G2 ( ). D. albida Blatch., 1924, 169.—Type in Davis collection; 
taken by him on Big Pine Key, Sept. 18. 
173 (15907). D. xanthomelena (Dalm.).—‘‘Florida” (Horn, 1889). St. 
Augustine (Ham.) as collaris (Ill.), a synonym. 
*174 (15910). D. mellicollis (Say.)——Capron (Sz. Ms.). LaGrange 
(Davis Coll.). Bradentown, Oct. (Wat.). At hand from Sanford, Lakeland 
and Dunedin, Feb.-Apr.; scarce at porch light and beneath cover. 
*175 (15911). D. collata (Fabr.)—Common along the sea-coast, where 
it occurs beneath cover, between the roots of grass and on low vegetation 
close to the water. At hand from Key West and Dunedin. Recorded from 
many stations, but inland only from Enterprise (C. & L.). 
XLIV. Argopistes Motschulsky. 
Small (3 mm.), hemispherical black and red species resem- 
bling Exochomus in general appearance; antennae gradually 
clavate, front coxal cavities open behind.
