394 Mi-. R. S. Bagiiall on new Thysanoptera. 



Hah. India, Maddur, Mysore, 30. viii. 1918, and Coimba- 

 tore, 7. ix. 1918^ single females with Dendrothripoides ipomece, 

 sp. iiied., on Ipoinea stcqjfiylina {Ramakrishna). 



Physotkrips andrewsi, sp. n. 



? . — Length c. I'-i mm. 



Belonging to the P. vulgatissimus gioup, having the an- 

 tennal joints 3 and 4 long, slender, atid fusiform. 



Colour uniform dark brown ; fore-wings brown, with the 

 basal fourth or more light, practically clear. Antennse 

 brown, joint 2 yellowish distally, 3 wholly light greyish- 

 yellow, and 4 basally greyish-yellow to light yellowish- 

 brown. Anterior legs wholly light greyish-yellow, inter- 

 mediate pair also light, but with the fore margin shaded 

 to a deepish brown — chiefly medianly ; |)osterior pair with the 

 femora dark brown, lighter distally, and the tibiee greyish- 

 yellow. 



Head transverse, dorsal surface irregularly transversely 

 striated ; ocelli placed well back, interocellar sette short and 

 stout, about equal in length to the width separating them. 

 Antenna3 about 2'.5 times as long as the head, relative lengths 

 of joints 2-8 ap|)roximately as follows: — 44 : 72 (with pedi- 

 cel) : 68 : 44 : 65 ; 5 : 7. Intermediate joints slender, very 

 approxinuitely of uniform breadth. Maxillary jKilpi long, 

 relative lengths of joints approximately 21 : 12 : 20. 



Pronotum transverse, approximately r3 times as long as 

 the head and about 8 as long as broad. Surface trans- 

 versely striated, sparingly and minutely setose, bristles at 

 each hind angle subequal in length, long and stout, between 

 0'55 and 0*6 the length of the pronotum. Legs somewhat 

 stout, especially the anterior pair ; regularly setose. Hind 

 tibiae with series of spines in the distal two-thirds (or tliere- 

 abouts) within, closely set, moderately long and stout, and 

 numbering a dozen or more, the terminal pair very long and 

 stout. Setffi of fore-wing somewhat long and stou^, 1 + 1 + 1 

 in the distal half of the upper vein, 24-26 and 12-15 on the 

 costa and lower vein respectively. 



Abdomen oblong-ovate, terminal bristles long. 



Easily distinguished from vulgatissimus by the coloration 

 of wings and legs. It conies very near indeed to the Japanese 

 P. palUpes, Bagn., and differs chiefly in the coloration of head 

 and thorax, the longer intermediate antennal joints, the longer 

 pronotum (14 : 10), the longer pronotal bristles, whilst there 

 are differences in the chietotaxy of the head. Both palU^es
