and Volcan de Chiriqui, Panama. Champion also records its 

 occurrence in Guatemala. Nothing is known of its food plants. 



Gargaphia albescens Drake 



1917. Drake, Ent. News, xxviii, p. 22S. 



Small, elongate. Head with spines short. Basal pair somewhat decumbent. 

 First two and fourth segments black, except basal third of fourth. Antennae 

 very finely pubescent. Pronotal hood comparatively large for the size of the 

 insect. Carinae normal, with a distinct row of areoles, nearly i)arallel for 

 entire length, slightly farther a])art in front. Lateral margins romiding with 

 two rows of areoles in costal area, subcostal with two, and discoidal with three. 

 Length of discoidal area about one-half of length of elytra. All membranous 

 portions more or less hairy and clear white. Legs whitish. No color mark- 

 ings. Length, 3 mm.; width, 1.3 mm. 



Type locality: Sacramento, California. Type in collection of 

 Mr. C. J. Drake. Eleven specimens from this locality are in 

 the United States National Museum collection. 



There are no recorded food plants.

Resembles opacula Uhler, from which it can be separated by a 

 slightly wider and more flaring membranous margin of the prono- 

 tum, and by the three rows of areoles in the costal area of elytra. 

 Otherwise the description given for opacula will apply equally as 

 well for iridescens. At some later date it may be proved that 

 this is a synonym of opacula. Intergradations between the tw'o 

 have been at hand for study, but the writer hardly feels warranted 

 in making this a synonym of opacula with but this sort of evidence. 



Specimens have been examined from California, Arizona, New 

 Mexico, and Texas. Champion records it from North Mexico. 



Food plant records include Ambrosia species, Solan uni species, 

 Maiva species, and sand nettle. 



Gargaphia condensa new species 



Head with spines erect, basal spines long. First two and fourth segments 

 of antennae black, third reddish brown. Pronotal hood small, about twice as 

 long as broad. Pronotum black, membranous portions hairy. Carinae 

 parallel and low. Lateral margins angular, with three rows of areoles at widest
