No. 2.] Notes on insect pests from the Entomological Section. 59 



"tail." Antennae and feet absent. The usual large spine is pre- 

 sent just above the abdominal process. The lac-tubes are, as usual, 

 situated on the thoracic region : they are prominent, sub-cylindrical, 

 and bearing groups of excretory glands. The body of the insect is 

 very inconspicuously segmented, and on each margin of a segment 

 is a group of very small subcircular spinneret-orifices. 



Female of the second stage, covered by a waxy test, which at 

 first is elliptical and very slightly convex, but later becomes sub- 

 circular, with a central small elongated and narrow corrugated 

 lamina, from which depressions radiate to the margin. These depres- 

 sions are comparatively more conspicuous than in the adult tests 

 producing a more deeply corrugated appearance. Usually the 

 median region is reddish or orange-coloured, the marginal corruga- 

 tions whitish or yellowish ; but the difference between a late second 

 test and an early adult are not easy to make out. These second- 

 stage tests average about -^-^ in. in diameter in the early stage. The 

 enclosed insect is at first elongated-elliptical, gradually assuming 

 a subglobular form, colour red. I have not been able to satisfy mj^' 

 self as to the antennae, or feet ; but probably both are absent. 



I have not observed any larvae after emergence ; but in some adult 

 specimens examined there were a great number of embryonic larvae ; 

 these were red, elliptical, tapering posteriorly, the abdomen ending 

 in two divergent and conspicuous anal tubercles, each bearing a long 

 seta and some short hairs. The antennae and feet were not suffi- 

 ciently developed for observation. 



Male pupa, covered by a test of red or yellowish red wax. The 

 form of the test is elongated-elliptical, convex above, the median 

 region moderately rough and frequently simulating the form of the 

 elliptical segmented enclosed pupa ; the margin is corrugated as in 

 the case of the female. Length of the test about ^\j- in. At the pos- 

 terior extremity there is a flat-hinged plate, on lifting up which the 

 adult escapes. The enclosed pupa is dark-red. 



Adult male dark-red, the wings hyaline with red nervures. 

 Length of the body about -^-^ in. exclusive of the spike. Antennae of 

 ten joints, the first two short and tubercular, the next five long and 

 slender but diminishing somewhat to the seventh ; the eight and ninth 

 shorter and thicker, the tenth as long as the fifth, very thick and 

 sub- elliptical : all the joints bear several hairs. Feet long and slen- 

 der, but with no special character. The abdominal spike is straight 

 and rather long, being nearly as long as the abdomen. The ter» 

 mintil abdominal tubercles bear each two setae, from which spring 

 moderately long cottony "tails/'
