﻿nor angle of the head) ; apical margin of clypeus minutely notch- 

 ed, extending apically distinctly beyond the apical margin of the 

 genae. 



Male: vertex nearly twice as long as pronotum ; maximum 

 width greater than median length. 



Female: vertex about twice and a half as long as the prono- 

 tum ; maximum width less than median length. 



Length 3^ mill. 



Hab. New South Wales, Alittagong (Jan., K. ). 



This species, (which I name in honour of Dr. W. T. Brigham, 

 Director of the Bernice Pauahi Bishop Museiim in Honolulu, 

 whose "Index to the Islands of the Pacific" (1900 Alem. Bishop 

 Mus. I, 1-172) is of such great value to the student of Pacific 

 Faunas), seems very distinct frqm such Paradorydia as lanceo- 

 latnin, fovcolatnin, etc., but I can see no generic differences be- 

 \ond the nmch shorter head. On this and the straight lateral 

 margins of the vertex, 1 found a new subgenus Deltodorydium. 



5. ovidii sp. nov. 



Allied to the last, but the head more elongate, the head and 

 pronotum forming two-fifths of the entire length, and the lateral 

 margins are concavely curved, the species thus falling into the 

 ty]3ical subgenus. It differs from P. fovcolatuni Sign., by the 

 much less spatulate head and less pointed tegmina. 



Length (female) 5 mill. 



Hab. New .South Wales, Mittagong (Jan.). 



Dorycephaliis. 



3. trilineatus. 



The exact habitat was "New South Wales, Sydnev ( |an., 

 K.)." 



Tribe lassiiii. 



Van Duzee includes this as a tribe cf his Jassina. but it is far 

 more distinct from his 'Deltocephalini' than these are from his 

 'Subfamily Acocephalina.' The lassinae are characterized by 

 the vertex being perpendicularly raised at the sides and base, 

 the latter being practically truncate between the eyes, and dis- 

 tinctly narrower there than the apical margin of the scutellum. 

 Head and eves distinctly narrower than the pronotum. Frons
