median furrow, the sides of the median segment rounded, obscurely 

 reticulate ; petiole shorter than thorax, remainder of abdomen as long 

 as head, thorax, and petiole united ; pygidium punctured. Black; the 

 mandibles in the centre, the second and third abdominal segments, and 

 sometimes the margins of the remaining segments, dark red ; tibiee at 

 base and the whole of the tarsi' more or less testaceous, calcaria pale ; 

 clypeus and front covered with short, silvery pubescence ; thorax, 

 femora below, and apical two or throe segments of abdomen with longer, 

 sparse, greyish pubescence ; wings hyaline, the first recurrent nervure 

 is received into the second cubital cell before the middle, the second 

 recurrent nervure into the third cubital cell just beyond its inner angle. 



Long. 12 mm. 



Habitat : Mount Abu ; throe specimens. 



This species belongs to Cameron's Annulipes group. Of the Indian 

 species it comes next to P. re/iventr/s, but can easily be distinguished 

 from it by the petiole being shorter than the thorax, whereas in rufi- 

 ventris it is as long as head and thorax united. 



Stigmus cuculus, n. sp. (Dudgeon M. S.) 



" 5 Differs from S. eongruus (Walk.) in being less than half the 

 " size, in the whole of the antenn?e being testaceous, clypeus subtrian- 

 " gular and slightly produced ; tubercles not white. 



" Long. 3-5 mm. 



"Habitat : Holta, Kangra Valley. 



" This small insect nests in the holes bored in soft pine by a minute 

 " species of beetle. It stores its nest with aphidas, and lives in colonies 

 " of thirty or forty together. My specimens were procured from a table 

 " in my verandah, where I had many opportunities of watching their 

 "habits. It is much smaller than the other two Indian species of the 

 " genus." 



Passalckcus dtjdgeoni, n. sp. 



9 Head and mesonotum finely and closely punctured, median 

 segment finely reticulate, abdomen imptmctate or nearly so ; clypeus 

 broader than long, subtriangular, its anterior margin rounded, labrum 

 triangular, mandibles blunt at apex ; eyes divergent towards the 

 vertex, their distance apart there being half as much again as at the 

 base of antennae ; front without tubercles, scape of antennas as long as 

 the first four joints of the flagellum united, these latter joints being 

 subequal. apical join' of flagellum the longest ; mesopleur;e with a
