the customary measurements, and, in addition, has reduced the lengths 

 of antennal segments to microns. In most other respects the phin 

 adopted l)y Hinds has been followed. The writer has redescribed the 

 three species of Miss Daniel {CryptotJiripscallfornicux, Eiithrtps pyy'i,, 

 and SerlcotJirqjs ajjteris) to make their descriptions conform with the 

 others. 



CLASSIFICATION OF CALIFORNIA THYSANOPTERA. 



KEY TO THE SUBORDERS AND FAMILIES. 



I. Female with a saw-like ovipositor. Terminal abdominal segment of female coni- 



cal, of male usually broadly rounded. Wings usually present; fore pair 

 strongest, with more or less well-developed veins; double fringed behind. 

 Membrane of wings with microscopic hairs Suborder Terebrantia. 



A. Antennai with nine segments. Fore wings broad and rounded, 



with prominent ring vein and cross veins. Ovipositor up- 

 curved ( A ) Family ^olothripid^. 



B. Antenna.' with six to eight (nine?) segments. Wings present or 



absent; when present usually narrow and pointed at tips. Ovi- 

 positor downcurved (B) Family Thripid.e. 



II. Female without ovipositor. Terminal abdominal segment tubular in l)oth sexes. 



Wings usually present, both pairs similar; front pair with only a rudi- 

 mentary, median, longitudinal vein; wings with simple fringe on both 

 margins except fore wing, which is double fringed on posterior edge near 

 tip by a few hairs; membrane of wings without microscopic hairs. 



Antennae eight-segmented Suborder Tubulifera. 



(C) Family Phlceothripid^. 



KEY TO THE GENERA. 



(A) Family yEoLOTHRiPio.T:. 



1. All segments of antenna' freely movable and diminishing in size grad- 



ually at tip. Maxillary palpi seven-segmented, labial palpi four- 

 segmenteil (1) Orothrips, new genus. 



2. Last four segments of antenna' closely united and together shorter than the 



fifth. Maxillary palpi three-segmented, labial palpi four-segmented. 



(2) jEolofhrrps Haliday. 



3. CaHothrips Daniel." 



(B) Family Thripid.e. 



L Antenme with eight segments (nine?). 



a. Wings wanting; jirothorax almost as large as pterthorax; body with or 



without reticulated structure (3) Genus <S'mco//iryjs Haliday. 



a\ Wings fully developed. 



//. Body with markedly reticulate surface; last segment of antenna 

 drawn out and very much longer than the seventh. 



(4) Genus ITeUotJtrips Haliday. 

 b\ Body without reticulate structure; eighth antennal segment only 

 a little longer than the seventh. 



(5) (Tenus Euthrips Targione-Tozzetti. 



« Caliothrips woodworthi, new genus and species, was described in Entomological 

 News for Novemt>er, 1904 ( Vol. XV, No. 9, pp. 296-297) . The writer of the present 

 paper has been unable to see the type specimen, but from the description believes 

 that it will prove to be none other than the male of Ifeliolhripxfasclatus Pergande, (ir 

 a closely related species.
