92 THE ENTOMOLOGIST’S RECORD. 
appears to be an undescribed species, but I prefer to wait in the hope 
of further material before describing it. 
(14) Camponotus (Myrmogonia), sp. 8% sminor. In default of soldiers 
I propose to give a brief description of this ant, which I cannot trace 
in any published description, though it appears to come close to 
Forel’s gibbinotus. 
L. 7-8 mm. — 
Dark castaneous, pronotum and anterior half of head clearer, antennae and 
legs clear testaceous. Basal borders of gaster segments testaceous. 
Mandibles 5-6 dentate, clypeus carinate; head longer than broad, with 
parallel sides, narrowing behind the eyes, the occipital border feebly emarginate. 
The whole thorax in profile forms a high and regularly curved arch, the base 
of epinotum sharply compressed. The whole body is superficially and transversely 
reticulate-striate. 
Body with a few stiff erect hairs, none on the scapes, and on the 
tibiae only on the underside.

Anopheles and Malaria. 
Malaria is due to the presence of the terrible little parasite dis- 
covered by Laveran, a French medical man, some thirty years ago, and 
called Laverania malariae. 
In the spread of Malaria the part which the mosquito plays is that 
of a carrier of the young parasites or spores, which are present in large 
numbers in the saliva of the mosquito. Thus, when the Anopheles bites 
a human being to feed upon the blood, some of this saliva carrying 
spores enters a minute capillary through the wound. ‘The spores thus 
introduced into the circulation immediately attack and penetrate the 
red corpuscles of the blood, where they develop and multiply. This 
multiplication of the spores, by simple division or splitting, is termed 
“ Schizogony,”’ and the spores are themselves called “‘ Hnhaemospores.”’ 
The attacked corpuscles are destroyed, setting free spores which attack 
other corpuscles. Sexual forms of the parasite soon appear in the 
blood of the infected person and pass into the next mosquito, which 
bites the sufferer to feed upon the blood. These male and female forms 
are sausage-shaped when transferred to the alimentary canal of the 
gnat (Anopheles), but in a short time become sphericle. The male form 
produces spermatozoa, which fuse with and fertilise the female spheres 
or ege-cells. A series of metamorphoses then ensues in which a worm- 
like form partly pierces the intestinal wall and is nourished by the 
enat’s blood. Cysts are formed which finally break up and produce 
fresh spores, which accumulate in the salivary glands in the body of 
the affected mosquito, ready to still further spread this fell disease. 
This second spore production is known as ‘‘Sporogony,” and the spores 
produced are termed ‘ Exotospores,” to distinguish them from the 
former series. 
Thus the parasite is absolutely dependent upon the mosquito 
for part of its development, and the moral therefore is ‘‘ Do away with 
the Anopheles and you do away with the parasite.’’ In order to do this 
the carrier of the parasite must be located, and this is the task which 
the Local Government Board want to carry out; to map out with all
