at Montalban, February 22, 1918, on fruit heads of Solanum 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 
gense 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.
