of fifth and tapering to tip, two and one- half times as long as the two-jointed style. 

 Prothoras wider than head. Pterothorax one and one-quarter times the width 

 of prothorax, longer than broad, the metathorax tapering to abdomen. Legs mode- 

 rately long, a stout spine on tlie inner side of each hind tibia at tip. Pore-wings 

 dark brownish-grey, veins darker, a row of stout spines on the outer edge ; hind 

 pair lighter. 



Abdomen elongate-ovate, widest at the fifth segment, where it is only slightly 

 wider than pterothorax : transverse, brown dorsal patches on segments two to seven, 

 largest on the second segment, and diminishing in size to seventh. Spines on apical 

 segments nine and ten long, and those at posterior angles of segments seven and 

 eight not quite so long. 



Hahitat : Wylam-on-Tyne, Northumberland ; Kew Gardens, 

 London; Glasneviu Gardens, Dublin. Injurious to various hothouse 

 Orchids, Odontoglossum, Cypripedhim and Zi/r/opetaluvi. I am indebted 

 to the late Geo. Nicholson for the specimens from the Kew Gardens. 



Though the arrangement of anal spines differs from that in all 

 other species, I can only refer this insect to the genus Anaphothrips, 

 Uzel, and, apart from this, it may at once be recognised by its dis- 

 tinctive coloration. I have a single mutilated specimen of the male, 

 which has a ])air of very short, stout spines at the apex of the ninth 

 abdominal segment above. 



This species is the " Yellow Thrips " or '' Yellow Orchid 'J'hrips " 

 of most horticulturalists.

SOMK PnORID.lPj IN DUMBARTONSHIRK IN 1908, 

 WITH DESCRIPTION OF A NEW SPECIES. 



BY J. K. MALLOCH. 



During the year 1908 there was but little addition made to the 

 species already recorded belonj^ing to the section of the PhoridcB with 

 spinous tibia?, the only two which occurred being vifrea, Wood, and 

 (jracilis, Wood. Of the former I obtained three ^ (^ on the hillside 

 above Bonhill. The only specimen I found of (jracilis was one $ , 

 which agrees in all particulars with Dr. Wood's description of the 

 species, but a ^ which I have had for some time unrecognised in my 

 collection, differs in having no bristle at the base of the middle tibite. 



Of the species belonging to the group with four scutellar bristles 

 and without tibial bristles, lately dealt with by Dr. Wood in this 

 Magazine, I have taken several species, one of which I find has not
