present in elliotii. A female, compared with one of Smith's 

 cotypes of elliotii, is somewhat smaller, and has the first two 

 abdominal segments more shining and strongly punctured. The 

 general structure and the colour of the bands (brilliant yellowish 

 green shot with vermillion) are quite the same. Gribodo's 

 description of N. incerta, from Java and the Sulu Islands, 

 evidently applies to our species. 



Nomia elongata, Friese. 

 Males ; Los Banos, Luzon (Baker 6). Determined by Friese, 

 who described the species from Java. This is close to the 

 Australian N. yseudoceratina, Ckll. Smith described two species 

 of the same type, with clavate abdomen, from the Malay region : 

 N. ceratina from Sarawak, and N. clavata from Gilolo. Just at 

 present I am not able to say how N. elongata can be distin- 

 guished from ceratina and clavata ; they are at least very closely 

 allied. N. clavata may perhaps be separated by the more 

 highly-coloured tarsi. 



Nomia elo7igatula, n. sp. 

 Males ; Los Banos, Luzon (Baker 3850). A small species with 

 clavate abdomen, like N. elongata, but smaller (length 6-5-7 mm.), 

 with the stigma clearer red and the apex of wings less distinctly 

 infuscated. The knees are bright ferruginous, and the flagellum is 

 red beneath, these parts being only very obscurely reddish in elongata. 

 The really decisive character, however, is found in the fifth ventral 

 abdominal segment, which has a pair of bright red spots, each 

 bearing a pair of black tubercles, the posterior of which is compound. 

 N. elongata has not this character. 



Nomia takauensis philijjpineni^is, Friese, n. subsp. 

 Both sexes from Los Banos (Baker 312). N. takauensis was 

 described from Formosa, only the male being known. The meso- 

 notum in true takauensis has the hair almost felt-like ; in the 

 Phihppine insect the hair is thin, exposing the finely punctured 

 surface. The legs appear to be darker in the Philippine form. The 

 female differs in the usual sexual characters ; the first four abdominal 

 segments have apical ochreous hair-bands, while the fifth is densely 

 margined with soot-coloured hair. The head is broad, and the 

 flagellum very short. Hair on outer side of hind tibiae white. 



Nomia palavanica, n. sp. 

 5 . Length 7 mm. or slightly more ; similar to N. takauensis 

 philippineyisis, but differing as follows : stigma much lai'ger, pale 

 amber, not dusky ; head shorter, being transversely oval ; apical half 

 of mandibles red ; mesothorax more closely punctured ; hair on and 

 about scutellum not bright fulvous ; hind margins of abdominal 

 segments castaneous, with weaker hair-bands, hair on apical margin 

 of fifth wholly light ; first abdominal segment not so broad ; anterior 

 and middle knees bright ferruginous. The stigma is larger and
