at Montalban, February 22, 1918, on fruit heads of Solatium ver- 

 bascifolium and on young shoots of Eugenia calubcob; and one 

 specimen was collected in the forest of Culasi near a 700-meter 

 elevation. 



The nymphs (Plate I, fig. 4) were all collected at Montalban 

 on February 22, 1918, on Eugenia calubcob and are all in the 

 last instar. Since the immature form of this insect has not been 

 previously recorded, a brief description is given as follows: 



Brilliant yellow, marked with black; length, 5 millimeters; 

 width, 3; smooth, shining, not punctate, very sparingly pubes- 

 cent, head tuberculate above ; pronotum with three strong spines, 

 one on median dorsal line and one on each side ; mesonotum with 

 one strong median dorsal spine; abdomen with a strong lateral 

 spine on each segment except the last; wing pads reaching the 

 first abdominal spine. 



Head much broader than long, bright yellow, smooth, shining, 

 impunctate, only lightly pubescent at margins; base strongly 

 elevated at middle and bearing a strong tubercle on each side 

 of median line; eyes very prominent, produced laterally, jet 

 black; ocelli not visible; sutures distinct; inferior margins of 

 genag almost transverse; clypeus longer than broad, extending 

 for more than half its length below the inferior margins of the 

 gense, tip rounded and somewhat pilose. 



Thorax distinctly divided into prothorax, mesothorax, and me- 

 tathorax, not punctate, sparingly pubescent, shining, jet black in 

 front, bright yellow on sides and behind spines; humeral angles 

 very prominent, auriculate ; pronotum having three strong spines, 

 one on median dorsal line pointing upward and slightly backward, 

 one on each side above humeral angle projecting upward and 

 outward, an extension of dorsum behind median spine extending 

 to the spine of the mesonotum ; mesonotum with strong central 

 spine at posterior margin; metanotum without spine, bright 

 yellow above, jet black at sides ; wing pads very well developed, 

 reaching backward as far as the first lateral spine of the 

 abdomen. 



Abdomen broad, flattened dorsoventrally, bearing seven dis- 

 tinct segments, of which the first six have strong lateral spines 

 extending directly outward, these spines gradually becoming 

 longer from before backward ; entire abdomen shining, impunc- 

 tate, not pubescent, black above, yellow on sides, apex strongly 

 curved upward; anal tube long, upraised, wider at base than 

 at tip.
