 (COCCID.E) OF THE UGANDA PROTECTORATE.

Mr. C. C. Gowdey, the Government Entomologist o£ Uganda, is to be 

 congratulated upon the number of interesting forms which he has forwarded 

 to this country for identification from time to time. Many of the species, 

 if not all, are of economic importance, and, judging by their numbers, must 

 have sorely taxed the plants upon which they were found. 



One of the most remarkable facts connected with the Coccids from the 

 Uganda Protectorate is that a very large percentage of them has been 

 parasitized by small Chalcidids. I have never before seen so many indi- 

 viduals destroyed by these parasites from any other part of the world. A 

 study of the bionomics of these insects would no doubt prove of great 

 interest from an economic as well as from a biological standpoint ; and 

 it is to be hoped that it will be possible in the future to give some attention 

 to this interesting group of the Hymenoptera. 



Inglisia conchiformis, sp. n. 



Test of adult female (fig. 1) shaped like a miniature bivalve shell, standing 

 -erect upon the branch of its food-plant, with the hinge uppermost and its 

 lower edges resting upon a pad of white secretion, which often projects 

 beyond the test, forming a narrow flocculent fringe ; surface of test with 

 distinct vertical striae ; pale horn-colour, with confluent streaks of golden- 

 yellow and brown-yellow. 



Length 5-6*5 mm. ; width l*5-2*5 mm. ; height 2*5-3*5 mm. 



Female^ adult. — Very elongate ; margin with a narrow band of stout 

 conical spines, consisting of three or four irregular rows in front and behind, 

 but merging into two at the sides. Stigmatic areas with a few additional 

 spines between which are a number of circular spinnerets. Antennae and legs 

 short, the former of seven segments. Tarsi ivith a deep pseudo-articidation. 



Length 5 mm. (average). 



Puparium of male. — Opaque glassy-white, surface somewhat scaly ; margin 

 with an irregular fringe of stout glassy-white filaments. Shape somewhat 

 like the puparia of the genus Lecanium, but the so-called " coronet " is not 

 clearly defined. 



Larca ellipsoidal, but narrowing posteriorly. Antennae relatively short, 

 being scarcely half the length of the legs ; segments six in number, the 

 third longest and stoutest. ' Legs very long, normal. Anal lobes large
