SUBFAMILY II. — COREIN^. 247 



host plant, the heart-leaved umbrella-wort, Allionia nyctaginea 

 Michx. Described from Texas and Mexico. Known also from 

 Ohio, Illinois, Minnesota, Dakota, Colorado, Oklahoma and 

 Arizona. Hart (1907, 238) records it from the sandy regions 

 of northwestern Illinois as ''common on Rhus aromatica Ait., 

 Allionia nyctaginea Michx. and a variety of other plants, espe- 

 cially along roadsides." 



178 ( — ). Catorhintha borinquensis viridipes var. nov. 



Elongate-oblong. Head dull yellow with two ill-defined blackish 

 stripes on front and a wider irregular one behind each eye; pronotum, 

 ciavus and corium dark reddish-brown, the area just within both apical 

 and basal angles of pronotum vaguely blotched with fuscous ; scutellum 

 paler reddish-brown, its extreme tip yellowish; membrane pale brown; 

 connexivum rather broadly exposed, strongly reflexed, segments 2 — 4 

 blackish-brown, with incisures and basal third of each yellowish, 5 and 6 

 wholly pale; under surface greenish-yellow tinged with reddish, the 

 flanks of each pleurite and ventral with a rather large round black spot; 

 a smaller similar spot on the outer side of each coxa? and two dots 

 near middle of second and third ventrals; beak black, its basal joint 

 paler; coxa? and basal two-thirds of all femora dull yellow, apical third 

 of femora and all the tibia? bluish- or bottle-green ; tips of tibia? and of 

 each tarsal joint blackish. Antenna? with joint 1 black, extreme tips 

 of 2 and 3 and middle of 4 fuscous-black; remainder of 2 and 3 and 

 apex and base of 4 greenish-yellow; joint 1 stout, feebly curved; 2 and 

 3 slender, 2 longer than either 1 or 3 ; 4 stout, fusiform, almost as long 

 as 2, its middle as thick as 1. Subantennal plate much reduced in size. 

 Pronotum with sides straight, feebly converging from base to apex; disk 

 with a distinct transverse impression across apical fourth, the area in 

 front of this sparsely and finely punctate, remainder of disk, as well as 

 those of ciavus and corium coarsely, rather thickly and evenly punctate. 

 Membrane with veins more numerous than in our other species, all of 

 them nearly straight and but one or two of them forked. Length, 

 11.5 mm. 



Royal Palm Park, Fla., Dec. 15 ; a single male beaten from 

 fallen leaves of royal palm in the dense hammock on Paradise 

 Key. The spines on head behind the bases of antennse are 

 almost as prominent as those of Anasa armigera (Say) while the 

 veining of the membrane approaches closely that of Margus 

 obscurator (Fabr.). The typical C. borinquensis Barber (1923b, 

 1) is a Porto Rican species. It is smaller and more slender 

 with spines on front of head reddish and distinctly more 

 slender; black markings on head, antennse and connexivals 

 wanting; femora and lower surface thickly covered with red 

 dots ; small black spots on sternal pleurites only and tibia? red- 

 dish-yellow.
