In explanation of the above synonymy, it may be said that on 

 the accompanying plate are given several detail drawings, wliich 

 show the close similarity obtaining between Phlcrothrips, Acan- 

 tJiothrips, and PselapJiotlirips, and, consequently, the relationship 

 of all with Eupathithrips and Sedulothrips. They are discussed 

 below under the species headings. 



Acanthothrips nodicornis Renter, Fig. 7. (Drawn from a 

 specimen ex collection O. M. Reuter, from Helsingfors, Finland.) 

 It will be noted that the eyes of this species differ in no essential 

 features from those of Pselaphothrips (Fig. 2); they are as finely 

 and closely faceted, fully as prominent, very nearly as contiguous 

 anteriorly and show almost as great a tendency to surround the 

 ocelli; while on the ventral surface, it may be added, they are just 

 as well separated. 



Acanthothrips albiviitatus Hood, Fig. 6. The antennte of this 

 species are very similar to those of Pselaphothrips, in color, form, 

 and chffitotaxy. With but few exceptions, every bristle and every 

 sense cone finds its analogue in Pselaphothrips (Fig. 3) . Further- 

 more, the antennte are inserted more on the ventral than on the 

 dorsal surface of the head ; and the latter, while not crested dorsally, 

 is nevertheless slightly elevated along the median line. 



Acanthothrips magnafemoralis Hinds, Fig. 5. The third antennal 

 segment is in this more slender than in the other species of the 

 genus, and approaches the Pselaphothrips-Evpathithrips-Sedulo- 

 thrips type very closely.

' The names ^.olothripidse, Thripidoe, and Phlnoothripidoe were proposed by Uzel in 1S95, 

 and should be credited to him, instead of to Haliday. The latter proposed three family names — 

 Coleoptrata, Stenoptera, and Tubulifera, — the last being employed also as a subordinal term. 

 According to modern ideas, Haliday's names are invalid, because not formed from the oldest 

 genus of the family by the addition of -idse to the root.
