discoidal arises just outside the middle of the subcostal, obsolete, just a base, 

 curves so as to have convex surface towards tip of wing, no longer than the first 

 discoidal. All veins brown. Style — (Figure 2.S8, 4). Short, wider at the base 

 than at the apex, which is nearly straight across, rough, with long hairs or spines, 

 green, length 0.07 mm., width at base 0.08 mm. 



APTERors viviPAHors FEMALE (Figure 238 B) 

 Length 1.;? nnu., width of the abdomen 0.7 mm. Body — Flat, widest just 

 in front of the cornicles, covered with long curved hairs or spines, well seg- 

 mented, very small. Prevailing color — Rich green with a distinct light green 

 or yellow cross on the dorsum (hence the name crucis), light spots or areas

around tlic basis of the cornicles and a liglit posterior spot. The main axis of 

 the cross extends in a longitiidin.-il liiii- on the dorsum from the base of the head 

 to the end of the style, while the cross bar is a transverse band across the middle 

 of the body. Surrounding the liglit area of the cross are dark green areas, which 

 are darker than tiie rest of the body and which help to bring out the distinctness 

 of the markings. Due to the smallness of tiiis species the cross cannot be dis- 

 tinctly seen witiioiit the air of a liand lens. Heart — Large, considerable wider 

 at the base than at the front, rounded between the .intennw, which are far apart, 

 covered with long hairs, dark green with median b;ise lighter. Eyes — Large, 

 dark red, distant from the bases of the antennae. Antennae — (Figure 238, 7 and 

 8). Reaching to the middle of the abdomen, slightly longer than half the length 

 of the body, with fiw long h.iirs or spines, imbricated, light yellow with the tip
