Mr. Willoughby Ellis's energetic assistance— the species was distinctly 

 rare and difficult to get. One ? obtained by beating a dead sallow 

 branch near Kirtlington Park (Oxon), 21.ix.13, is apparently referable 

 to this species. 



HoPLANDROTHRIPS COLLINSI, sp. 11. 



Length about 1*5 mm. 



Colour almost as in H. ellisi ; antennal joints 6 to 8 wholly dark brown, 3 

 yellow, brown distally, 4 with basal third and 5 basally yellow or yellowish 

 brown ; basal joints greyish near base. 



Head only 1"1 times as long as broad, slightly converging posteriorly, genal 

 spines minute. Mouth-cone almost reaching across prosternum. Antennae l - 7 

 times as long as head ; relative lengths of joints : — 12 : 17 : 30 : 27 : 23 : 22 : 18 : 14 ; 

 3 and 4 clavate, broader than any of the others ; 5 broadly clavate, broader 

 than 6 to 8. 



Prothorax and setae about as in H. ellisi. Pterothorax a little broader 

 than long ; sides of metathorax converging to abdomen. Hind-legs compara- 

 tively a little longer than in H. ellisi ; fore-legs only moderately crassate, with 

 the pair of teeth near apex of femur within smaller than in H. ellisi ; tibiae 

 longer and more slender, without tooth at basal third within ; tarsal tooth 

 somewhat short, sharp. Coxae as in H. ellisi. Wings as in H. ellisi, 10 cili a 

 duplicated. 



Tube - 6 the length of head ; terminal hairs, bristles of 9th segment and 

 lateral abdominal setce as in H. ellisi. 



Readily separated from H. ellisi by its smaller size, shorter and relatively 

 broader head, and the coloration of the antennae. 



Type : In Hope Collections, University Museum, Oxford. 



Hob. : One £ taken with H. ellisi, Balsall Common, Warwickshire ; 

 and another <J by beating dead ash branches, Enslow Bridge (Oxon), 

 September, 1913. 



The genus Hoplanclrotlirips is "apparently composed of numerous 

 somewhat closely allied forms and is known from Europe, Africa, and 

 North America. 



The European species Phloeothrips annulipes, Reut. (Finland) ; 

 minor, Uzel ; parvus, Uzel (Bohemia) ; brevicollis, Bagn. (Norway) ; 

 and albovittatvs, Schille (Poland), are known from females only, and it 

 is probable that some or all of them should be referred to Hoplandro- 

 thrips. Of these, albovittatus is distinctive on account of the coloration 

 of the prothorax, whilst annulipes, parvus, brevicollis, and Hoplandro- 

 thrips bidens, Bagn. (Hungary) , are separated at once from the species 

 just described by having the intermediate and hind tibiae yellowish 

 both basally and apically. P. minor has the head only slightly broader
