82 TIIK KNrOMOl.OlilSX's UECUKIJ. 



This individual was bred in my obsei'vation nest of ^f. (jrainiiiirola ; the 

 colony of which I obtained at Box Hill on May 1st, 1910, and have 

 still under observation. It pupated in ]\Iay, 1911, enieroed in July, 

 and died on December 15th. It was a pugnacious little ant and would 

 attack a paint-brush when presented to it. It was generally to be 

 found wanderuig- about the nest, or sitting by itself, away from the 

 other ants. 



No. 3. (Fig- 3.) Foniiira i^autjuinea, Latr., partly winged $ . l^ug 

 up in a /''. saiKininea nest at Woking, on June 12th, 1914. The right 

 posterior leg is short, and deformed, the femur being short and abruptly 

 bent, the tibia short, and the tarsus twisted and deformed. The tarsal 

 claws are short and blunt, being almost absent. The right forewing, 

 though broken, was still present, which would appear to show that this 

 female dated from, not less than, the year previous to that of capture. 

 The formation of the leg may be due to injury received during an 

 earlier instar ; or possibly to neglect, as in the case of the antenna; of 

 A/, (/laiiiiiiicola recorded above. This latter supposition, however, is 

 not so likely to occur in a nest in natui-e as in one in captivity ; more- 

 over, the shortness of the femur and tibia, etc., are a,gainst this. 



No. 4. (Fig. 4.) I'Oniiico nijibarbia, F., ^ . Both the antenna", 

 the labial palpi, and all six legs are deformed, being twisted in all 

 directions. This ant (and a similar specimen) was reared m an obser- 

 vation nest of F. rnjibarbiii, the colony of which was taken at Wey- 

 bridge, on July 10th, 1912. These two cripples, though quita unable 

 to walk, lived for some time in the nest. I am inclined to consider 

 their condition to be due entirely to neglect; their pupal skins not 

 having been properly removed. Although 1 had the nest in question 

 under observation for six years, and the queen laid eggs regularly, very 

 few ants were reared. The workers appeared to resent captivity, and I 

 eventually liberated them. 



No. 5. (Fig. 5.) l-'onitica fiisca, L., S • Taken at Cratloe, Co. 

 Clare, Ireland, in 1895, and presented to me recently by Mr. Stelfox of 

 the Dublin Museum. The left antenna is deformed ; the scape being 

 shorter than that of thjB right one, which is of normal length, and the 

 joints of the funiculus are soldered together into a sort of spiked club 

 (see figure). Although most of the joints of the funiculus are so mixed 

 up, yet it is almost possible to recognise 12, which is the normal num- 

 ber of joints (not counting the scape, which makes it 13) in the S of 

 Form tea. 



T'his ant is otherwise quite normal ; excepting that the mandibles 

 possess 4 or 5 well-developed teeth. This latter character, though 

 remarkable''" in itself, has nothing to do with the deformity of the 



* Tliis struck me as being remarkable as, though I have examined hundreds 

 of male specimens of F. fus^ca, I have never seen a specimen with toothed man- 

 dibles before ; moreover, in the following works, both in the tables and under the 

 descriptions of the species, the J' of F. fnsca is stated to possess mandibles without 

 teeth — Andre, Spec. Ilijiu. Furope (ISSl) ; Uonisthorpe, lirithli Aiil.t (19I.5) ; 

 Emery, PdlaearktiKclie Formicidcn (lHOill ; I'ormiciddr Italiaiiae (19111) ; Forel, 

 Foiiiinis <lc la Saisxe (1874). Nevertheless Wheeler, in his l!evigu»i of tlte Ant)! of 

 the Geiiuit Fovmica [Bull. Mtis. Coiupar. Zoo/., 53, 495 (U)18)] , when describinp; 

 the ,} of F. fused, L., states that the mandibles are •■ often, it not alwajs, denticu- 

 late " ; so the fact was evidently well kno.vn to liim.
