sexes of one species was correct, and propose that they should be 

 united, the trivial name of wakcfieldi being retained for the species. 

 The variation in size of the individuals is remarkable, some of the 

 females being about 30mm. long, while other examples of the same 

 sex scarcely attain 15mm. The largest male I have seen is about 

 21mm. long. 



Thoramwi parriji, Cand. I have made acquaintance with the 

 male of this species by means of an example from the late Andrew 

 Murray's collection. It is extremely similar to the corresponding 

 sex of T.fercdayi, but has the meso- and meta-sterna between the 

 middle coxae more consolidated, the produced angles of the antennae 

 less elongate, the sides of the thorax without constriction, and the 

 punctuation of the interstices rather more obsolete. Thus the 

 species T. ivakeficldi, T. parryi, T. feredayi, and T. lavithorax 

 appear to be valid, though the female of T. feredayi is still un- 

 known, and, no doubt, will prove to be difficult to distinguish from 

 the smaller individuals of the corresponding sex of T. wakefieldi. 



Cryptohypnus. 



1994. C. pallipes, n.s. (Sharj); Trans. Boy. Dub. Soc, 1886, 

 p. 400.) Niger, antennis fusco-testaceis, basi, palpis, pedibusque 

 pallide tlavis ; protliorace magno, convexo, nitido, angulis posteriori- 

 bus elongatis, sat divergentibus, crebrius fere subtiliter punctato, 

 medio canaliculato ; ehjtris subtiliter striatis, interstitiis subtiliter 

 punctulatis. 



Long., 11mm. 



This is allied to C. thoracicus, but is readily distinguished by the 

 very fine sculpture, and the quite pallid femora and base of the an- 

 tennae ; the pubescence is short and extremely fine ; the thorax is 

 elongate, the length along the middle being just equal to the greatest 

 breadth ; the sides are a good deal rounded, and there is a very dis- 

 tinct constriction in front of the angles ; these latter are rather 

 divergent, there is a rather long basal plica on each side in addition 

 to the carina on the angle. 



Greymouth. Helms. Two examples, probably female. 



Obs.- — Cryptohypnus thoracicus, Sharp. Mr. Helms has sent me 

 from Greymouth a series of this species ; some of the examples are 

 only half the size of the typical example, and are besides narrower 

 and more parallel, with straighter sides to the thorax ; these indivi- 

 duals represent, I have little doubt, the male sex, and they come so 

 near to C . frontalis that I feel doubtful whether this latter may not 

 prove to be only a very sparingly punctate variety of C. thoracicus : 

 it may, however, be retained as distinct till further evidence can be 

 obtained to settle the point decisively. 



1995. C. picticornis, "■«• Elongate, nearly parallel, elytra 

 somewhat depressed, slightly nitid ; clothed with fine ash-coloured 

 hairs, becoming flavescent towards the sides, and more sparingly 

 ilistributed on the thorax ; fusco-niger, most part of femora (and
