An extremely abundant species wherever found, but swarming in 

 certain grassland locations. 



Mestobregma thomasi Caudell. 



St. Louis, Missom-i, Aug. 27, 3 c? , 1 9 . 



These specimens are not separable from male individuals from 

 Indiana received from Prof. Blatchley. 



Found in a field overgrown with tall weeds in the city. 



METATOR McNeill. 

 Metator pardalinus (Saussure). 



Waco, Montana, Aug. 4, 1 d^, 3 9 . Knob Hill, Colorado Springs, 

 Colorado, Aug. 17 and 22, 1 c^, 2 9 . Prairie land, Colorado Springs, 

 Aug. 18, 6 d", 2 9. 



Of the series here mentioned nine possess red or reddish wings, five 

 yellow wings and one (Colorado Springs, prairie, Aug. 18, 9 ) has the 

 wings orange. The evidence of this material would thus support the 

 view held by Caudell,^^ w^ho regards Psinidia maculosa Saussure as 

 merely the yellow winged form of pardalinus, an opinion entertained 

 as possible by Saussure in the original description, his words being, 

 'Annae prgecedentis varietas?" 



The Waco record is the most northern for true pardalinus, but if 

 maculosa is identical the range is extended as far north as Fort McLeod, 

 Alberta. 



The specimens taken at Waco were captured among the sage-brush 

 where the species appeared extremely plentiful. I also found this 

 species plentiful at Colorado Springs, in the prairie wherever there was 

 a damp depression. The insect is not swift of flight and may be 

 easily taken with a net. 



CONOZOA Saussure. 

 Conozoa sulcifrons (Scudder). 



Grand Junction, Mesa Co., Colorado, Aug. 15, 11 d*, 12 9 . 



Several specimens of this species were submitted to Mr. A, N. 

 Caudell for comparison with material in the U. S. National Museum, 

 and his remarks are quite interesting and worthy of record. In part 

 he writes : ' ' They are not Conozoa wallula ; they are either C sulcifrons 

 or hehrensi .... I can scarcely tell these species apart. Behrensi is 

 supposed to have shorter wings and elytra, have the median carina of 

 the prozona more deeply cut and have the wing-bands wider. I have
