Bingham it also occurs in Ceylon. Bingham describes the ab- 
domen as “deep obscure bottle-green.” 
Mesotrichia bombiformis (Smith). 
Evidently common at Manila, where Mr. McGregor took it, 
July 23 to 26, at flowers of Peltophorum inerme and Antigonon 
leptopus. Also one from Obando, Bulacan Province, Luzon, 
October, 1919 {McGregor) . 
Mesotrichia philippinensis chlorina Cockerell. 
Luzon, Manila, 9 females, collected as follows : March 2, 1919, 
at flowers of Gliricidia sepium (Jacq.) Steud. ; June, and July 
23, at flowers of Peltophoncm inerme; July 26, at flowers of 
Antigonon leptopvs; and September 21. All collected by Mc- 
Gregor. One specimen, taken in September, has the green wings 
of chlorina, but the yellow band on thorax posteriorly is nar- 
rowed to a line in the middle, so that the insect approaches true 
philippinensis. Another, taken July 23, has the wings mainly 
purplish, approaching philippinensis in this respect; but the 
thoracic band is as in chlorina. Two have a distinct patch of 
yellow hair beneath the wings, but this is usually wanting or 
reduced to a few inconspicuous hairs. In the type of chlorina 
it is present but small. The absence of this patch is a character 
of the form hilineata (Friese), but none of our bees is small 
enough for that. 
With the females comes a male; Manila, July 26, at Antigonon 
leptopus. It is the insect which I provisionally regarded as the 
male of M. bakeriana Cockerell, but it now seems likely that it 
belongs to chlorina. 
Megacbile valdezi (Cockerell). 
Luzon, Manila, February 12, 1919 {McGregor) , 1 female. 
Megacbile mcgregori Cockerell. 
Luzon, Bulacan Province, Obando, October, 1919 {McGregor) , 
1 male. In my table of Philippine Megachile this species is 
placed among those in which the tarsi have no long fringe 
behind. This is erroneous ; all the tarsi have long creamy-white 
fringes, those of the hind tarsi in front. From M. laticeps 
Smith it is easily known by the white hair bands, broadly in- 
terrupted or reduced to a few hairs in middle, on abdominal seg- 
ments 2 to 4. 
Antbopbora korotonensis var. stantoni (Cockerell) . 
Luzon, Manila, February 11, 12, and 14, 1919, 1 female and 
8 males; October 9, 1918, a male at flowers of Stachytarpheta
