SOME ADDITIONAL COLEOPTERA FROM CAVAN. 



BY G. W. NICHOLSON, M.A., M.D. 



As I had the good fortune to take a specimen of Pteros- 

 Hchus aterrimus, Pk., at Cloverhill, in September, 1913/ 

 I revisited that place at the end of May of last year, a 

 time that I thought would be suited for finding it again. 

 I was, however, doomed to disappointment. Diligent 

 search in every conceivable spot, both at Cloverhill and on 

 several of the neighbouring estates, produced no result as 

 far as this insect was concerned. In spite of this my time 

 was not wasted, and I now give a list of the more note- 

 worthy of my captures. 



Among them there are the following additions to the 

 Irish list : — 



1. Ips iv-guttata, F. Six specimens in the burrows of 

 Hylastes palliatus, GylL, under the bark of the stump of a 

 Scotch Fir, at the felhng of which I had assisted the previous 

 September, in a wood at Cloverhill, on June 4. 



2. Dryophilus pusillus, Gyll. Twelve specimens beaten 

 out of a pine on the avenue at Castle Saunderson, Co. 

 Cavan, on June 2, and another at Cloverhill on June 4. 



3. Salpingus ater, Pk. A specimen beaten out of a 

 Birch on the bog at Cloverhill on May 25. This may be a 

 doubtful species, but my specimen agrees in every detail 

 with the description in Fowler's " British Coleoptera." 



4. Trypodendron lineatum, 01. I found a single specimen 

 under the bark of the same stump as the Ips on June 4. 



The following species, all of which, I believe, are ad- 

 ditions to the county list, may be mentioned. Except 

 where otherwise stated the locality is Cloverhill : — 



Bembidium punctulatum, Drap., B. bipundatum, L., 

 B. assimile, Gyll., and B. aeneum, Germ., on the shore of 

 Lough Erne at Castle Saunderson. ; here I also found a 

 purple variety of Anchomenus parumpunctatus, F. ; Brady - 

 cellus placidus, Gyll., in moss beside one of the Cloverhill 

 lakes ; Coelambus v-lineatus, Zett. ; Hydroporus pictus, F. ; 

 H. lineatus, F. ; H. nigrita, F. ; H. memnonius, Nic. ; 

 Agabus chalconotus, Pz. ; A. affinis, Pk. ; Ilybius ater,
