H. isthmalis is readily distinguished from H. plebeins, 

 Ckll., by the area of metathorax much more strongly sculp- 

 turedj and not produced apically. 



Halictus docldi, sp. n. 



? . — Length about 8 mm. 



Rather sleuder, black, the first two abdominal segments 

 light ferruginous, with a large transverse black dorsal patch, 

 that on the first brown-black, straight behind and obtusely 

 pointed in front, that on the second straight in front and 

 behind, extending right across the segment, its upper border 

 not far from the base ; hair of head and thorax ochreous, on 

 mesothorax thin and fuscous ; tubercles and adjacent upper 

 border of prothorax with a dense ochreous fringe ; scuteilum 

 and postscutellum. except at extreme sides, covered vrith a 

 dense reddish-ochreous felt-like tomentum, which also 

 extends, somewhat thinner, as a pair of subtriangular patches 

 on hind part of mesothorax ; head broad ; mandibles dark 

 red apically; clypeus and supraclypeal area shining, sparsely 

 j)unctured ; front dull, except at sides, quite hairy ; flagellum 

 dull reddish beneath ; mesothorax very finely and densely 

 punctured ; area of metathorax very finely irregularly 

 wrinkled, without a sharp boundary ; posterior truncation 

 Avitli salient upper corners ; tegulae clear ferruginous, 

 minutely roughened anteriorly. AVings dusky yellowish ;

 red on inner side, except at apex, and middle tibiae with a 

 large bright ferruginous patch anteriorly ; hind spurs 

 simple. Abdomen long and parallel-sided, with extremely

By the dorsal patch of dense tomentum this resembles 

 //. Itichardti, Ckll., from which it is easily known by the 

 colour of the abdomen. It also approaches Parasphecodes 

 basilautiis^ Ckll., and should perhaps be referred to Para- 

 sphecodes.
