446 BRITISH GENERA, IN THE 



Sp. 4. Thr. Apt. rufa. Fern. Fulva oculis et rostri apice 

 fuscis. 



Thr. rufa. {Gleichen, Tab. 16. fig. 6, 7.) Gmelin, No. 11. 



• Nicholsons Journal of Nat. Phil. Vol. XII. 



PI. 8. fig. 1. (very bad.) 



In profusion in the spikes of grass and cerealia. 



Sp. 5. Thr. Apt. nilidula. Fem. Testacea abdominis inci- 

 suris, SfC.Juscis. 



One half smaller than the preceding. 



Found on a muddy sea-coast, I believe on the heads of 

 Plantago maritima; but not common. 



Subgen. IV. — Thrips. 



Prothorax cequilatus : antennce stylus articulo 6*°. brevior : 

 ocelli ires {alceqne ut plurimum) : segmentum feminag ulti- 

 mum compresso-conicum inerme. 



Thrips spp. Auctt. 



Within the limits to which this sketch must be confined, 

 I cannot pretend even to indicate all the species I have seen. 

 At some other time I hope to resume the subject. The follow- 

 ing divisions are not exactly those which I should adopt, did 

 the space allow me to characterize the species ; but they will 

 serve for the present purpose. 



N, B. The males are mostly one-half smaller than the 

 females, and paler, sometimes widely different in colour. 



Sect. A. Tihia et metatarsus anticus apice intrinsecus uncinati. 



Sp. 6. Thr. Ulicis. Mas et Fem. Elytris nigricantibus basi 



albidis. 



In profusion on flowers of Ulex Europcea. I once met 

 with several of the half-grown larvae in the keel of the blossom. 

 They were much paler than in any other species that I know. 

 The same species sometimes strays into the blossoms of Crocus 

 Susianus ; and I once found an individual on corn, so late as 

 July.
