Hoplothrips angusticeps (Bagnall) 

 Dolerothrips angusticeps Bagnall, igiod : 688. 



One micropterous male without antennae remains in the collection. 

 LECTOTYPE <$. Hawaii : Molokai, Kalae, 7.viii.i893 (Perkins 172). 



Hoplothrips barbatus (Bagnall) 

 Dolerothrips barbatus Bagnall, igiod : 683-684. 



Holotype (J. Hawaii : Kona, 4,000 ft., under rotting log, ix.1892 (Perkins). 



Hoplothrips bicolor (Bagnall) 



Dolerothrips bicolor Bagnall, igiod : 688-689. 



The colour of the unique micropterous female, which lacks antennae, does not 

 appear to differ radically from the other Hawaiian forms such as barbatus, dubius and 

 ovatus. 



Holotype $. Hawaii : Oahu, Kaala Mts., 2,000 ft., i.1893 (Perkins 56). 



Hoplothrips dubius (Bagnall) 

 Dolerothrips dubius Bagnall, igiod : 691. 



Only one macropterous female of this species remains in Bagnall's collection. 

 LECTOTYPE $. Hawaii : Molokai Mts., 4,500 ft., 21.xi.1893 (Perkins). 



Hoplothrips flavipes (Bagnall) 



Dolerothrips flavipes Bagnall, igiod : 685-686. 



Of the four females and one male, all micropterae, labelled flavipes in Bagnall's 

 collection only one female specimen has not been treated with strong caustic alkali 

 and this is here designated as lectotype. The figure in Zimmermann (1948 : 402) 

 by Bianchi and labelled flavipes Bagnall is almost certainly not this species. In 

 flavipes the postocular setae are softly pointed and their length is about equal to half 

 the head width. The epimeral and postero-angular pronotal setae are equal in 

 length to the postoculars, but the midlaterals are rather longer. The antero- 

 angulars are small except in one oedymerous male, in which they are about half as 

 long as the postoculars. None of the Hoplothrips species described by Bagnall from 

 Hawaii have pronotal setae as figured by Bianchi, moreover antennal VIII is con- 

 stricted basally in lateral view in flavipes (cf. Zimmermann, 1948 : 393). 



LECTOTYPE $. Hawaii : Maui, Haleakala, 5,000 ft., iv.1894 (Perkins).
