sides, the mesonotum not at all. The latter lias an elongate, median 

 tubercle. Meso-epinotal suture narrow and deep. Epinotal teeth 

 short, as long as two-fifths of the interval between them. First 

 segment of petiole with a very short and blunt tooth below in front, 

 much the same as in C. Scutellaria ; somewhat wider than long. 

 Second segment with a complete median groove and 2 not very 

 projecting discs. Abdomen cordate. $ minor shining, lightly reticu- 

 late, distinctly but sparsely and finely punctate, the abdomen and 

 back of the head nearly smooth, the cheeks sparsely striate. ^ major 

 less shining, more sharply reticulate all over, the head in greater part 

 very finely and closely striato-rugulose and reticulate, with shallow 

 and widely spaced punctures which are distinct and abundant. 

 Pubescence very fine, scattered. Pilosity almost entirely wanting, 

 except on the ventral surface. ^ major, brownish-black, mandibles, 

 cheeks, club of antenna and articulations of the legs dark yellowish- 

 red. ^ minor, yellowish or dark yellowish-brown, posterior half of 

 the abdomen blackish-brown.

Fig. 47. — C. gallicola, Forel. 



The ^ $ before me are all small examples, 24 mm. or less, derived 

 from an incipient nest. In these the head is as wide as long, excluding 

 the mandibles. Frontal area feebly defined. The 2nd-7th joints of 

 the flagellum wider than long. The pro-mesonotal suture is very 

 shallow but fairly visible. The declivity of the mesonotum is quite 

 two-thirds as long as the anterior plane, and the latter has a rounded 

 tubercle in front. The 1st segment of the petiole is as long as wide, 

 with the anterior angles somewhat obtusely truncate. 



Apart from these slight differences these specimens agree fairly well 

 with Forel' s description ; they have also been determined as gallicola 

 by Dr. Santschi. 



9- 8 mm. (hitherto undescribed). Blackish-brown, tarsi and 

 flagellum ferruginous, mandibles castaneous red. Erect pilose hairs 

 very sparse on the abdomen, and almost entirely wanting elsewhere. 

 Pubescence moderately plentiful, decumbent ; fairly long on the legs 

 and antennae. Sides of the head, in front of the eyes, finely and 

 longitudinally striate, behind the eyes very superficially rugulose and 

 feebly punctured, moderately shining. Clypeus nearly smooth in the 

 middle. Mandibles coarsely striato-punctate. Mesonotum and scutellum
