THE ENTOMOLOGIST S BECOED. 



mens are of this dark coloration, rufo- or castaneo-testaceous, with the 

 cuneus bright red and the hind tibiae dark. 



In the general collection at the British Museum, standing under 

 the name M. infusum, there are specimens from Austria which were in 

 Dr. Eger's collection, and still carry his labels bearing the name M. 

 infusum ; but as they are strongly pilose, they clearly belong to 21. 

 heckeri ; one is pale and appears to represent the var. lethiernji,Yi&h., 

 of which [ have seen an authentic specimen from Mr. Champion's 

 collection, and the other is dark like the Weybridge and Oxahott 

 examples. 



Mr. Donisthorpe tells me that his captures were all made from fir 

 trees, at the foot of which in each case there was a nest of the ant 

 Formica rufa, while no specimens were found on trees not so accom- 

 panied ; and he considers that, like Pilojihorus, which occurred with it, 

 the bug may have some sort of association with the ant. Beuter gives 

 as the ^habitat of M. heckeri, -JJlmus, etc.; but what the "etc.'' 

 covers nowhere appears, though it may, perhaps, include fir-trees. M. 

 infusum is with us most commonly found on oaks, but it is recorded 

 on the Continent from fir-trees also, and in the light of Dr. Eger's 

 specimens mentioned above, the question naturally arises whether these 

 fir-tree specimens may not, after all, have been M. heckeri. On the 

 continent, M. heckeri occurs in France, Italy, Austria, Hungary, 

 Eumania, Greece, and S. Eussia, and it appears to be rather more 

 southern in its distribution than M. infusum.. 



1 am much indebted to Mr. Donisthorpe for kindly placing three 

 of his captures at my disposal.
