extronicly densely punctured ; mesothorax minutely reti- 

 cuhite, with rather sparse small punctures ; hind spur with 

 only extremely minute saw-like teeth. 



Ilab. Waipara, New Zeahiud, Nov. 21, 1915 {Guy 

 Brill ill). 



Mr. Biittiu took four females, two with dark tcf^ulre, two 

 with ruro-tcstaeeous tegula?. I thouj^litat first that 1 could 

 distin<::uish two species, that with dari;er tegulaj being the 

 true H. sviithii (fainiliaris. Smith) and the other new. 

 After minute comparisons, in which I am fortunately able 

 to inchule a co-type of smitliii from Smithes collection, I 

 coucliulc that there is only one variahle s|)ecies. The hind 

 margins of the first and second ahdoaiinal segments of 

 H. sinii/iii are very narrowly vibrissate witii white hair, 

 though this is not always very evident. Cameron (Trans. 

 N. Zealand Inst. vol. xxxii. p. 17) separates smithii from 

 surdidus and huttoni by the character of the base of median 

 segment (metathorax), but his statement is unsatisfactory, 

 as the sc ulpturc in smithii is very delicate, appealing rugose 

 under a low magnification, but showing tine plictc under a 

 hiiiher. 



Halidus gulosus punctiferus, subsp. n. 



? . — Like H. gulosus {H. arcuatus gulosns, Ckll.), but 

 mesothorax more closely punctured, especially at sides < f 

 middle, where the punctures are hardly separated by a s])ace 

 ecjual to the width of one ; th(! bind margins of the abdo- 

 minal segments are very narrowly or often scarcely at all 

 pallid. Wings brownish. Very like H. craterus, Lovell, 

 but easily separated by the impunetate hind margin of first 

 abdominal segment and the larger stigma.
