punctatissima, Rog.— ? , three, ? , three, Gibraltar, also one $ possibly belonging 

 to this species, but haying extraordinarily developed eyes, as large in proportion as 

 those of the $ . I sent this specimen to Dr. Emery for examination, and he replied 

 that if he had seen two examples of this form he should not have hesitated in con- 

 sidering the cliaracter specific, but having only seen one, he thinks it may be an 

 individual anomaly. 



Family MYEMICID.E. 



Mthmecina, Curt. 



Latreillei, Curt. — <J , two, Tangier. 

 Tetkamorium, Mayr. 



ccBspitum, Latr. — $ , a few, from Gibraltar. 

 Leptothorax, Mayr. 



tuberum, Fab., var. luteus, For. — $ , several, Gibraltar, also a single $ and ? 

 with the head dark, and the ? very small, not larger than the $ . These I have 

 communicated to Dr. Emery, but he does not think it would be wise to establish a 

 new race on isolated examples. 



nigrita, Emery. — $ , a good series from Gibraltar, some with the metathoracic 

 spines quite pale, yax-Jlavispinus, Andre. It is this species which I quoted in error 

 as Rottenbergi, Em., in Ent. Mo. Mag., xxv, p. 17. 



recedens, Nyl. — ^ , two, and ^ , two, of tliis rare species from Gibraltar. 

 MoNOMORiUM, Mayr. 



Andrei, n. sp.—~ ^ • Testacea, nitens, caput nitidissimum fere impunctalum sub- 

 elongatum, postice leviter excavatum. Antennarum scapo capitis basin fere attin- 

 gents, flagelli articulo primo quatuor segmeniibus simul sumptis cequali, articulis 

 2—8 transversis brevissimis, 9-10 subaqualibus articulo apicali elongato quatuor 

 prcecedentibus longiore. Mesothorax nitidus, lateribus postice rugulosis ; metathorax 

 inermis, rugulosus planiusculus postice decliviter rotundatus. Abdomen nitidum, 

 postice infuscatum petioli articulo primo brevi, postice valde tumido et rotundato, 

 ruguloso, secundo rotundato ruguloso. Pedes flavi. Long., 2 mm. 



Gibraltar, several. 



Like minutum, Mayr, in shape, but differing in the colour and in the sculpture 

 of the metathorax, also in the much more glabrous surface and the less pilose an- 

 tennee ; from small workers oi gracillimum, Sm.,to which Prof. Mayr pointed out its 

 resemblance, it differs in the much shorter intermediate joints of the flagellum, 

 the longer head, and shorter 1st joint of the petiole. 



Salomonis, L. — $ , $ , a fair series of each. Cap Negro, ^ , a very few, Gibraltar. 



var. subopacum, Sra. — ? , $ , plentifully, Gibraltar. 

 APH.ENOGASTER, Mayr. 



barbara, L. — c? , ? , $ , common, Gibraltar and Tangier. 



structor, Latr. — (?,?,?, sparingly, Gibraltar. 



pallida, Nyl., var. Leveillei, Em. — (J , ? , ^ , a fair series of the winged forms, 

 but only five $ , Gibraltar. 



crocea, Andr^. — $ , a fair series from Gibraltar. 



testaceopilosa, Luc. — This species has been sent in some numbers from Gibraltar 

 and Tangier ; it occurs in large colonies and is very active. The workers from 

 Gibraltar appear to belong to typical testaceopiluia, those from Tangier appear to
