126 THE ENTOMOLOGIST. 



the middle on segments 1 to 4, those on 3 and 4 abruptly ending some 

 distance from lateral margin ; venter brown ; claws simple. 



Hah. Corpus Christi, Texas, October 20th, 1905 ; two females 

 (F. C. Pratt). Sent by Mr. Crawford. Probably from flowers of 

 Helenium. 



Pcrdita coreopsidis, n. sp. 



? . In my tables (Proc. Phila. Acad.) runs as near to snowii as 

 anything, as also does the male. Its appearance is most like P. m.ent- 

 zeliarum, but it is very different in detail. The female with spotted 

 abdomen might be considered to run to P. chamcesaracJm, but it is not 

 at all like that species. 



Length about 6f mm. ; head and thorax brassy green, very hairy ; 

 vertex dullish, mesothorax shiny ; mandibles dull yellow, the apical 

 part ferruginous ; labrum dark ; face-markings pale rather dull yellow, 

 consisting of a broad band occupying anterior margin of clypeus, and 

 sending a large pointed process upwards in the middle line, and trmis- 

 versely ohlong lateral marks, not at all produced upwards, nor reaching 

 even the level of top of clypeus ; metallic part of clypeus with a strong 

 rosy lustre ; scape yellow, with a dark band or streak above ; flagellum 

 dark above, dull yellowish beneath and at tip ; upper border of pro- 

 thorax, and tubercles, light yellow ; teguls yellowish hyaline ; wings 

 milky white, nervures and stigma faintly yellowish ; marginal cell 

 nearly squarely truncate, its post-stigmatal part considerably the 

 longest ; second s. m. large, third discoidal distinct ; legs with the 

 apices of anterior and middle femora, and their tibiae in front, yellow ; 

 abdomen broad, rather dull chrome-yellow, with narrow brown-black 

 bauds at the apices and bases of the segments, and a large black 

 spot on each side of first, anterior to the band ; in a variation the 

 bands are reduced to spots, namely, large transverse subapical subdorsal 

 spots on segments 1 to 4, and smaller, rounder, subbasal lateral spots 

 on 2 to 5. Venter yellow. 



^ . Somewhat smaller, with a large subquadrate head, the cheeks 

 with a large blunt protuberance or tooth ; face-marks more reduced 

 than in female, being confined to a large pale yellow mark occupying 

 the projecting corners of clypeus, and the linear lateral projection of 

 same, and a very small spot at each lower corner of face ; flagellum 

 orange, with some light markings at base above ; hind knees (as well 

 as the parts mentioned in female) yellow, and the tarsi yellowish or 

 pallid in front ; abdomen with the hind margins of the segments 

 rather broadly whitish hyaline, and the dark colour much increased, 

 occupying all of first segment except a fine yellow streak between it 

 and the hyaline margin, going also a little way up the sides ; second 

 segment dark, with a median subapical yellow band, and the posterior 

 lateral corners very broadly yellow ; third segment with a broad dark 

 basal band and a pair of spots (in the subdorsal region) ; fourth and 

 fifth with tliQ base broadly dark ; sixth with a broad dark basal 

 triangle ; venter yellow, heavily marked with brown. The reduced 

 face-markings, and hyaline hind margins of segments, recall P. sida, 

 female. 



Maxillary palpi 6-jointed ; labial palpi 4-jointed, the first joint less 

 than twice length of the others combined, length of second joint 150 //,
