 Seincophanes ocellatus. Dorsal views macropterous female at left, micropterous 

 female in middle. Male at right. Below, ventral views of female abdomen macrop- 

 terous at left, micropterous at right. Male extreme right. 



globular portion of abdomen; wings wanting or very rudimentary; abdo- 

 men at base slender; joints three to eight forming a sub-globular, slightly 

 flattened broad portion; a prominent pleural fold extending from the base 

 to end of seventh segment. 



Color: Head, thorax, elytra, base of abdomen, the second joint of 

 antennce, femora, tibia? and base of tarsi reddish brown; first joint of 

 antennae yellow; a bright yellow spot on elytra as in macropterous forms, 

 apex of second joint and all of third and fourth, and tips of tarsi fuscous. 

 Abdominal 4-7 segments black or pitchy brown entirely, beneath in two 

 triangles, the apices of which nearly meet in the median line. 



No brachypterous male has been observed. 



Macropterous form. — Female: Similar to brachypterous form but with 

 fully developed elytra and wings, a much less extended abdomen, and the 

 pronotum widened at base with prominent angles. Length, 2.50, to tip 

 of elytra, 3 mm. 



Head smaller and with front less convex than in brachypterous form; 

 antennae similar; prothorax much less tumid, narrower in front and widen- 

 ing posteriorly to form prominent humeral angles, and with the posterior 

 margin overlapping scutellum and base of elytra; scutellum similar or a 

 trifle larger; elytra broader and shorter than in males; the tip of corium 

 not projecting as an obtuse angle; wings reaching to tip of elytra; abdomen 

 slender at base, expanding to end of seventh segment, where they are 

 almost as wide as the folded elytra, then contracting sharply to tip, flat- 

 tened, the tip of ovipositor projecting.
