many stations as pulicaria (Germ.) which species, as differ- 

 entiated below, appears to be very scarce in that state. About 

 Dunedin marginella occurs on the foliage and flowers of various 

 plants, both in low mucky and high sandy soils, being especially 

 frequent in early spring on the flowers of the dwarf papaw, 

 Asimina parviflora Michx., while at Ft. Myers both it and C. 

 lateralis were taken in some numbers while sifting the debris 

 of subaquatic plants along the margins of an extinct wet 

 weather pond. 



Dallas (loc. cit.) records his types of marginella from "New 

 York : presented by Edward Doubleday," and not from Hud- 

 son's Bay as erroneously stated by Van Duzee (1904, 9). 

 Doubleday collected both in Florida and New York and it is 

 possible that the types of marginella were really from the for- 

 mer state if not from southern. New York. The C. nanella 

 McAtee, described by Malloch (1919, 215) from Virginia and 

 Maryland, is a synonym of marginella. As there is so much 

 confusion in the synonymy, the range of this small southern 

 form is difficult to state. Since it occurs as far north as 

 southern Indiana and New Jersey, it probably takes the place 

 of pulicaria in most of the southern states and has been re- 

 corded by Distant from Mexico. 22

Oval, convex, widest across the humeri. Black, shining; costal mar- 

 gin of elytra ivory-white or orange-red, this pale color widened at base, 

 crossing the subcostal nervure and covering the 

 apical half or more of corium; ends of fifth and 

 sixth ventrals and, in female, of genital plate, 

 yellow or orange-red; antennae reddish-brown, the 

 terminal joints darker; femora piceous, knees and 

 tibiae reddish-brown, tarsi paler. Head as broad 

 between the eyes as long, its apex less produced 

 and more obtuse than in marginella; cheeks more 

 finely, less closely punctate than there, the tip of 

 tylus slightly recurved, not tuberculate; beak 

 Fig. 13, x 8. reaching hind coxae. Disk of pronotum finely 



and shallowly punctate, more closely so in front 

 and on sides than on basal portion, the latter elevated above the base 



"Uhler (1863, L55) described Corimeloena minuta from Cuba, and there is no 

 character in his description which distinguishes it from marginella as here recog- 

 nized. Van Duzee (1904, 76) records minuta from Jacksonville. Fla.. and. in his 

 catalogue, from Florida and Texas. Barber (Ms.) states that minuta differs from 

 marginella by being "very closely and coarsely punctate." and states that Van Duzee 

 was probably in error in regard to its occurrence in the two States mentioned. Since 

 Van lui/.ee in his i!r_\". paper does not recognize it from this country, l have not in- 

 cluded il in (lie kevs.
