with a whitish film that also extends toward the underside at the sternum. Hood 

 not much inflated, cristate and shghtly tapering towards front; covering the head, 

 except the eyes, with quite large areoles at the sides near top and a few smaller ones 

 at lower part. The three pronotal carinse yellowish,the median one strongly declining 

 towards apex of the triangular posterior portion of pronotum, with, a row of long, 

 large areoles of which the middle ones are divided hy a few cross ner\nires and em- 

 browned; outer carinse very low, only half as long as the median carina, extending 

 from base of hood to sides of pronotal portion posteriorly; the triangular part of pro- 

 notum rather short, yellowish and finely reticulated; membranous pronotal margins 

 strongly rounded behind, reflexed, widening moderately at sides, narrowmg toward 

 the neck and reaching the lower part of hood close to the eyes, with two or thi'ee 

 rows of average-sized areoles. Elytra ovate, iridescent, extending one-haK their 

 length beyond abdomen, a httle less in the male; discoidal area pjTiform and short, 

 angularly raised at the outer nervure, somewhat rounded at apex and broadlj^ scooped 

 out on the upper surface, with three or four rows of quite large areoles at the widest 

 part. Subcostal area subvertical, wider than the discoidal area, having about five 

 rows of irregular small areoles, those of the upper row much larger; costal area broadly 

 expanded, with four or five rows of very large, more or less irregular areoles, dimin- 

 ishing to three and two rows at base. Surface of elytra very pecuUarly undulated, 

 with two transverse, sharp impressions, and another at apex formed by the outer 

 nervure of subcostal area; a Hght transverse fascia on basal half. Median nervure 

 of subcostal area strongly sinuate towards tip of elytra; sutural area at inner part 

 irregularly reticulated with rows of some extremely large areoles. Entire margin of 

 el}i:ra, lateral margins of pronotum, crest of hood, carinse, and most of the ner^-ures 

 beset closely with long, very fine hahs. Rostral groove uninterrupted, broad at 

 mesostemum and metasternum, angularly closed in front; rostrum reaching meta- 

 sternum. Abdomen of female broadly rounded at apex, in the male more elon- 

 gate, the sides of genital segment sinuated; at tip two strong claspers. Length 3.6 

 mm.; width of each elytron across widest part, 1.4 mm. 



Control 



Our experience has shown that it is not a difficult matter to control 

 these insects. They may be killed by a soap, and water spray, at the 

 rate of 1 pound soap to 10 gallons water. The spraj^ should be directed 

 at the under side of the leaves, and applied as soon as the njanphs are 

 observed. It may be necessary sometimes to spray more than once 

 during the season. Any good soap may be used without injurj^ to the 

 leaves. In the case of rhododendron, care should be taken not to spray 

 the plants while the hot sun is shining; otherwise the leaves will be 

 scorched.
