Corythucha hoodiana spec. nov. 



Hood moderately elevated, very broad, very abruptly constricted 

 at the middle, widely reticulated, the areolae becoming smaller at the 

 sides in front; anterior portion narrowed anteriorly, with the sides 

 depressed; posterior portion rounded, but not globose. Antennas 

 slender, clothed with a few long hairs, the basal segment nearly three 

 times the length of the second. Pronotum not very closely punctate, 

 with the lateral margins broad, reniform, bullate just back of the middle, 

 with the anterior and posterior margins .slightly turned up, the spines 

 on the outer niargin almost entirely obsolete; median carina highly 

 elevated, the areolae long-rectangular, except a few divided cells that 

 form a double row of nearly square cells ; lateral carinae raised anteriorly, 

 with three or four areolae. Mesosternal laminae diverging posteriorly, 

 the metasternal ones cordate; rostrum reaching the meso- metasternal 

 suture. Elytra broad, reaching considerably beyond the abdomen, 

 with large, nearly round, tumid elevations, with the outer margins 

 sinuate, slightly emarginate, and the lateral spines almost entirely 

 obsolete; costal area broad, unevenly reticulate, with three rather 

 irregular rows of areolae and a few extra cells near the base and hyaline 

 portion; sutural area broad, unevenly reticulate. Abdomen very broad. 

 Length, 2.5 mm.; width, 2.6 mm. 



Color: Pronotum, a spot on each lateral margin, a rather broad 

 l^and near the base of the elytra, another near the apex (except two or 

 three cells near inner margin hyaline), a spot on the posterior portion 

 of tumid elevation and a few small spots near inner margin brown. 

 Areolae mostly hyaline, the nervures whitish. Antennas and legs 

 testaceous. Body beneath black. 



Described from a 9 specimen, taken on Mt. Hood, Oregon. 



Corythucha eriodictyonae spec. nov. 



Hood low, narrow, amied with a few long spines on the sides, with 

 the median nervure sinuate, rather abruptly constricted back of the 

 middle, the anterior portion long and narrow and the posterior short. 

 Antennae clothed with a few long hairs; basal segment constricted 

 bevond the middle, more swollen and a little more than twice the 

 length of the second; fourth segment swollen towards the tip. Pronotum 

 punctate, tricarinate; median carina low, undulate, uniseriate, very 

 low near the middle and where it conjoins with the hoed; lateral carinas 

 widely separated from the hood, raised anteriorly, with 4-5 distinct 

 areolae; membraneous margins widely reticulate, long, rather broad, 

 armed with very long spines on the outer margins. Rostral sulcus 

 broad, the rostrum extending between the posterior coxae. Elytra 

 long, broad, the tumid elevations small, armed with very long spines on 

 thcouter margins; costal area broad, mostly triseriate, the areolae_ large 

 and not of a uniform size; subcostal areokc \'ery sm.all. Wings visible. 

 Length, 3.2 mm.; width, LS mm. 



Color: Nervures of hood, pronotal margins, and elytra yellowish, 

 shghtly marked with brown and fuscous; areolae hyaline. Pronotum
