I abstain from giving tedious details, as the accompanying outlines 

 will give a better idea of these creatures than many vpords, and I 

 fl^atter myself that they will now be unmistakeable, at least, until 

 other species of the same genus shall be discovered. I have not taken 

 ^ny characters from the under-side, the specimens being carded ; 

 hence the oral organs coiild not be described, but they may be pretty 

 safely assumed to resemble those of Belyta, Anectata, &c., and their 

 details would have been of little value. The under-side of the abdo- 

 men of the ?, should, however, have been examined, in order to count 

 the segments, the sutures being hardly visible from above. The 2nd 

 iand 3rd segments are soldered into one, which covers almost the whole 

 abdomen like a shield, leaving only the narrow edges of the apical 

 segments visible, and these, in the ? , are not easily counted.

NOTE ON TANTZONUS BOLITOPEIL^, MARSHALL, PARASITIC IN 

 THE NEW ZEALAND G-LOW-WORM. 



BY G. V. nUDSOlS^, F.E.S. 



During the early part of June a young friend of mine (Mr. Albert 

 Norris) informed me that he had found pupae of the New Zealand 

 "glow-worm" {Bolitophila luminosa) attached to rocks in the big gully 

 of the Botanical Gardens, Wellington, which, from their shrivelled 

 condition, appeared to have been killed by some parasitic insect. I at 

 once examined one of these pupae, and found that it had been destroyed 

 by a species of Hymenoptera, apparently nearly allied to the Family 

 Ichneumonidce. The pupa of the parasite was imbedded in a quantity 

 of refuse matter in the centre of the unfortunate glow-worm pupa. 

 As is often the case with the Rymenoptera a single specimen only 

 was contained in each host. 



On June 21st one of the parasites appeared in the perfect con- 

 dition. It was apterous, and resembled in the closest possible manner 

 a worker ant ; on a further examination, however, I found that the
