The paper wrappers iu which the specimetis were packed were all stained dull 

 crimson from contact with the waxen tests of these insects. Ceroplastes quadri- 

 lineatus, Newst., also produces a similar dye when crushed ; but although the 

 tests of these two species are almost identical in colour, there is no trace of the 

 four white lines in C. iigaiidce. Moreover, the female of the latter may be 

 easily determined by the papillate character of the derm, and the distinct central 

 and lateral tubercles. 



Ceroplastes galeatus, sp. n. 



Test of adult female. — Wax hard ; creamy white or dusky yellowish white ; 

 roughly hemispherical ; divided into distinct plates ; dorsum with a central dark 

 nuclear spot situate in a deep depression, the latter extending as a narrow 

 groove as far as the region of the anal lobes ; lateral plates separated by dark 

 depressed lines ; lateral margins over the stigmatic clefts projecting consider- 

 ably beyond the hemispherical portion, in the form of two peak-like extensions, 

 on both surfaces of which are the opaque white stigmatic bands ; area sur- 

 rounding the anal orifice almost denuded, so that the colour of the insect is 

 visible. Width, 4*50-5 ; length, 4-4-50 mm. 



Female, adult. — Hemispherical ; shining and uniformly castaneous ; cephalic 

 lobe strongly defined ; stigmatic clefts well marked. Antennse (fig. 9, a) of six 

 segments of which the third is much the longest; formula, 3, (2, 6,) 1, (4, 5,). 



Fig. 9. — Ceroplastes galeatus, Newst. ; «, antenna ; J, stigmatic cleft, with spines. 



Legs normal. Stigmatic spines (fig. 9, b) rather small, narrowly conical, and 

 more or less uniform ; they vary from 25-38 in number. Marginal spines 

 simple, and rather short. Derm cells ovate, rather large and widely separated, 

 though most numerous just within the margin. Anal lobes minute. Caudal 

 process obsolete. 



Food-plant not stated. Entebbe, Uganda, 10. VIII. 1910 (C. C. Goivdey). 



This insect belongs to that section of the genus Ceroplastes of which C.flori- 

 densis, Comst., may be taken as a type. The distinguishing feature of the 

 test is the lateral extension of the wax, which is seen best when the insect
