THE ENTOMOLOItIST S RECORD. 



say that I was looking for /uu/rmi, as I have always said that if the 

 nests of c.rsecta were worked for beetles in this country, that this 

 species would occur. In 1902, I went to Bournemouth to search for 

 this ant, and was joined by Mr. W. C. Jackson of that town, but we 

 failed to find any nests. In 1904, Mr. Jackson sent me some ants, and 

 said he had found a nest, so this year I determined to go down again 

 and examine this nest. We found two nests, but only one beetle was 

 taken, by me, out of the smaller one. F. e.rsecta makes a small nest 

 of ling and grass, and is very scarce in this country. 



When I got home I compared my beetle with a specimen of D. 

 kaijom, given to me by Father Wasmann, and found that the antennte 

 did not agree, joints 4-10 being much shorter and broader. I, there- 

 fore, concluded that I had got a new^ species, and sent it on to Father 

 Wasmann to examine. He compared it with all his Dinardas and 

 found that it agreed with the typical specimen of D. hagenai, taken by 

 Yon Hagens, and described by Wasmann in Wien. Knt. Zeit., 1889, 

 p. 281. This specimen he kindly sent for me to examine. It is 

 probable that this is the original form, and those taken by Wasmann 

 at Linz-am-Rhine, with F. e.vnecta, and redescribed in Dfutsch. Kiit. 

 Ztsrhr., 1894, p. 275, are either another species or a more recent 

 development. They have the antenna? longer and the sides of the elytra 

 somewhat turned up, etc. In mj" specimen the elytra are much 

 narrower than the thorax, the sides are not explanate or turned up, 

 and the edges are serrate, wbich will at once separate it from our other 

 species. It is smaller than 1>. dcntata, the colour is a lighter red 

 (more yellow), and the posterior angles of the thorax and elytra are 

 less produced. 



This is, perhaps, the most interesting discovery made as to the 

 inhabitants of ants' nests in this countr}^ since the late E. W. Janson 

 first took Hetacriux. sesquieornis. We now possess three species of Dinanla 

 — Dinarda ntaerkeli, only found with Formica rii.fa : D. dentata, found 

 with F. sangiiitica and F. fusca ; and I). Jiai/ensi, found with 1''. easccta. 



OLEOPTERA. 



Gramoptera holomelina, Pool, a (^ood species. — In the Fnt. 

 Jurord {antca p. 133), Mr. Pool described a totally black form of 

 (jrramoptera under the above name, and pointed out that he had taken 

 three specimens in 1904, and that a specimen just like these was 

 taken by Mr. E. A. Waterhouse, in Yorkshire, thirty j'ears ago. Mr. 

 Pool has now taken some thirty more specimens from the same haw- 

 thorn hedge at Enfield, and I had the pleasure of taking my series 

 with him on one occasion last month. I consider that this form is a 

 good species, since, in all these specimens, there is not the slightest 

 variation, nor are there any intermediate forms. Mr. Pool has taken 

 both 3 s and J s, which only differ from each other in size and length 

 of antennse, neither showing the slightest red on antennjB or legs 

 whatsoever, nor the slightest pubescence such as is found on nificoriiis : 

 he has also taken them in capida. G. niticornis is not uncommon at this 

 hedge, and it varies considerably, but not for one minute could the 

 true holomelina be mistaken for it ; however shght the red may be at 

 the base of the femora, the typical ruricornia pubescence will be found 

 on the elytra, and where the pubescence is more scanty the legs have
