196 GENUS GARGAPHIA 



of areoles at point of greatest width. Subcostal area with three rows. Apical 

 angle of discoidal area nearly median, slightly nearer outer side. Length, 4 

 mm.; width, 2.2 mm. 



Four specimens in the C. F. Baker collection, which is on deposit 

 in the United States National Museum, are the only representa- 

 tives of this species which I have examined. They bear a label 

 which states that the determination was made by Champion. 

 The specimens are from Alabama. No record of a food plant 

 is given. 



Fasciata Stal has been placed, by Osborn and Drake in 1916 

 and Van Duzee in 1917, as a synonym of tiliae Walsh. Osborn 

 and Drake state that their conviction was confirmed by Heide- 

 mann. This error of synonomy was probably due to the fact 

 that the specimens Heidemann determined first as fasciata were 

 later properly recognized as tiliae, and that he never examined 

 the specimens determined by Champion above mentioned. 



Fasciata may readily be separated from tiliae by the greater 

 length of head spines, greater width of pronotal margins and 

 narrower subcostal area. There is also no darkening of nervures 

 of elytra in fasciata, as there is in tiliae in the costal area opposite 

 the discoidal area. Fasciata more nearly resembles patricia 

 Stal.

 Basal spines long and more or less decumbent. First three segments of 

 antennae yellowish, concolorous and hairy. Fourth segment black, except at 

 base, and hairy. Pronotal hood small and narrow. Pronotum black, punctate.

 with four rows of areoles, nervures more or less darkened. Pronotum and its 

 parts cjuite hairy. Elytra with four rows of areoles in the costal area and sub- 

 costal with two. Length of discoidal area less than one half length of elytra.

A long series from Cordova, Mexico, collected by the late Mr. 

 Frederick Knab, are in the collection of the United States Nat-
