 Another addition to our list, belonging to the subgenus Cxlocrabro, Thorns. 

 This may easily be known from any other of the section by being entirely black, 

 and by tlie well defined basal area of the propodeum, surrounded by very strong 

 crenatures.

There are four British species in tliis section with well defined crenatures, en- 

 closing the propodeal area, gonager, podagricus, carbonarius, and aphidum ; aphi- 

 dum can be known at once in both sexes by its pale yellow clypeus, podagricus by 

 the dull but almost impunctate surface of the mesonotum, and gonager may be easily 

 known from carbonarius by the wide scutate anterior metatarsi of its S > and the 

 yellow rings at the base of the tibise of the ^ .

CRYPTOHYPNUS PULCHELLUS, L. 

 BY JAMES E. BLACK, F.E.S. 



During the summer of 1903, while working the banks of the 

 river Truim, a tributary of the Spey, about three miles from Newton- 

 more, Inverness-shire, the writer took two examples of a Cryptohypmis 

 which at first sight appeared somewhat different from the abundant 

 G. dermestoides var. qiiadriguttatus, Lap. These were submitted to 

 Prof. T. Hudson Beare, of Edinburgh, and to Herr Eeitter, and con- 

 firmed by them as O. pulchellus, L. 



A subsequent visit to the same locality the following year failed 

 to produce any more specimens, but in June of this year I took 

 several more examples of this rare species, and being joined by Prof. 

 Beare, we thoroughly worked the locality and obtained a number of 

 specimens. The species appears to be an extremely local one, only 

 being obtained on one particular spot on the Truim, and onl}^ two 

 examples were obtained on the banks of the Spey, although hundreds 

 of the var. quadriguttatus were observed. 



In this spot, a gravelly bank near the confluence of the rivers, 

 the two species occurred together, creeping amongst the gravel on the 

 grassy edges of the shingle beds. They could quite easily be dis- 

 tinguished from each other, after a little practice, even without
