BAGNALL'S THYSANOPTERA 77 



Holotype $ of major. Norway : Bygdo near Christiana, lime tree leaves, 

 27. vi. 1909 (R.S.B.). 



Holotype $ of williamsi. England : Surrey, Merton, on hazel sticks, 16.xii.1912 

 (C. B. Williams). 



4 Cryptothrips ' shavianus Bagnall 



Cryptothrips shavianus Bagnall, 1918a : 216-217. 



This species has a heavy conical tube much as in Acalluruthrips but it differs from 

 both that genus and Diplochelaeothrips in having antenna] VIII constricted basally. 

 The pronotum has a concave anterior margin but the fore tibiae are not armed as 

 they are in Pharetrothrips. A new genus will probably be required when further 

 material becomes available for study. 



LECTOTYPE [probably $]. Australia : Victoria, Healesville, Acacia linearis 

 branch with galls, 31.L1916 (R. Kelly). 



DACTYLOTHRIPS Bagnall 



Dactylothrips Bagnall, 1923c : 629-630. Type-species D. australis, by monotypy. 



This genus is apparently related to Adrothrips Moulton in the shape of the tube, 

 the armed fore tibiae and tarsi, and the absence of postocular setae and fore wing 

 accessory cilia. Abdominal tergites II to IV have two pairs of wing retaining setae, 

 but the lateral abdominal setae of tergites III to VII are borne on bifurcate tubercles 

 which extend medially. The pronotum is not long and only the epimeral setae are 

 well developed. 



Dactylothrips australis Bagnall 



Ihutylothrips australis Bagnall, 1923c : 630. 



Holotype $. Australia : Victoria, Healesville, dead Acacia dealbata, 17J.1914 

 {R. Kelly). 



DERMOTHRIPS Bagnall 



Dermothrips Bagnall, 1910c! : 677-678. Type-species D. hawaiiensis, by monotypy. 



Cuticle largely reticulate. Head longer than broad, sharply constricted basally ; cheek 

 setae arising from tubercles ; postocular setae close to inner posterior margin of eye, about 

 half as long as eye, one pair of postocellar setae rather shorter ; maxillary stylets V-shaped, 

 mouth cone rounded. Pronotal major setae small ; praepectus present, mesopraesternum 

 small. Fore wings when present without accessory cilia, basal wing setae small ; abdominal 

 tergites with two pairs of wing retaining setae. Pelta broad, tube weakly constricted apically. 



Dermothrips hawaiiensis Bagnall 



Dermothrips hawaiiensis Bagnall, igiod : 678-680. 



LECTOTYPE $ aptera. Hawaii, Mauai : Haleakala, over 5000 ft., x.1896 

 {Perkins) .
