uzeli, Zim. ; Haplothrips gowdeyi, Frankl., in flowers of Melanthera 

 deltoidea, in tobacco seeds and in galleries of Agromyza sp. on tomato 

 leaves ; Heliothrips liaemorrhoidalis, Bch., on leaves of Per sea gratissima 

 and mango ; Hoplandrothrips affinis, Hood, and Podothrips semi- 

 flavus, Hood, on sugar-cane at the base of the leaves ; Heliothrips 

 {Selenothrips) rubrocinctus, Giard, on leaves of Mangifera indica ; 

 Thrips ahdominalis, Crawf., in flowers of Bidens leucantha ; Thrips 

 tabaci, Lind., on leaves of Allium cepa and in flowers of Cruciferae ; 

 and a new species of Zygothrips at the base of sugar-cane leaves. 



Wood damaged by Cryptotermes, should be treated with carbon 

 bisulphide or bichloride of mercury 20 : 1,000. Other remedies are 

 arsenic acid distributed about cellars, which is taken on to the feet of 

 the insects and thus poisons them ; for wooden objects, books, etc., 

 1,000 cc. of methylated spirit, bichloride of mercury 20 grms., phenic 

 acid 25 cc, with sufficient shellac to produce a slightly adhesive 

 liquid, should be used. This should be brushed lightly over the covers 

 of books. Other injurious termites are Eutermes sp., in decayed wood, 

 and a new species of Calotermes, taken in the decayed trunk of Persea 

 gratissima, together with Arrhinotermes simplex, Hagen.

The fungi of Cuba that naturally infest injurious insects and exercise 

 some measure of control over them include : Aegerita webberi, on 

 Aleurothrixus (Aleurodes) howardi ; Aschersonia aleurodis, on white- 

 flies ; A. cubensis, on Saissetia hemisphaerica ; A. goldiana, on white- 

 flies on Citrus ; A. tnrbinafa, on undetermined species of Lecanium ; 

 A. viridans, on whiteflies ; Aspergillus jlavus, which apparently keeps 

 in check the sugar-cane mealy-bug [Pseudococcus sacchari] ; Botrytis 

 rileyi, on the larvae of various Noctuids ; Cephalosporium lecaiiii, on 

 Saissetia hemisphaerica and Coccus mangiferae ; Cordyceps barberi, 

 on the larvae of Diatraea sacclmralis ; C. dipterigena, on the common

The Encyrtid subfamily Signiphorinae is revised in accordance 

 with new material that has recently been collected. A key to the 

 genera is given, and Thysanus ater, Wlk., is redescribed. This species 

 is abundant in central Spain during July and August on the branches
