and narrower, the prothorax different in shape, and there are other minor 

 differences. 



Description of Female. — Head longer than broad, with elongate con- 

 cave-sided clypeus, evenly rounded temporal lobes, and slightly concave 

 hind margin, with very small median rounded projection on to prothorax ; 

 markings much the same as in the last species, save that the suture is much 

 more distinct, the acuminate point of the signature is forked anteriorly, 

 the inner antennal bands do not reach so far forward, and the occipital 

 bands are well defined ; prothorax with sides converging anteriorly, and 

 hind margin slightly convex ; metathorax with postero-lateral angles not 

 truncated, but acute, and with deeper and more angulated projection On 

 to abdomen ; hind margin with about 20 pustulated hairs, not 26. 

 Abdomen more roundly oval, with last segments not so much pro- 

 duced ; transverse bands not so distinctly angulated at apex, and 

 produced further inwards, leaving a much smaller clear space ; the 

 pustulated hairs of the segments generally fewer in number, ranging 

 from 6 on segment I, through from 12 to 14 on the intervening 

 segments, to 4 on segment 7 ; 1 to 3 hairs in the posterior angles, 

 except the first, which is without hairs ; genital blotch closely resembling 

 that of the last species, and more easily compared on reference to the 

 figures. 



Length, 1-97 mm. ; breadth, 0-91 mm. ; head, 0-66 mm. by 0-60 mm. 



Trichodectidae. 



Trichodectes climax Nitzsch, in Giebel (1874, p. 58, pi. 20, fig. 2). 



Many specimens of both sexes were obtained from the introduced 

 domestic goat (Cwpra hircus Linn.). 



The types of the new species and variety described in this paper are 

 deposited in the Dominion Museum, Wellington, New Zealand. Where 

 there has been sufficient material, cotypes have been retained in our own 

 collection. 



All the figures in this article have been drawn with a camera lucida, 

 and have been equally magnified.
