North-American Bees. 453 
Mr. Ehrhorn also sends Synhalonia acerba, Cr., 3, from 
this locality. 
Ceratina neomexicana, Ckll. 
A new locality is Rio Ruidoso, N. M., about 7600 ft., at 
flowers of Verbena Macdougali, Aug. 3 (C. H. T. Townsend). 
Ceratina submaritima Ehrhorni, subsp. n. 
$.—Length 4 millim. 
Yellowish green (submaritima is bluish green) ; face deci- 
dedly narrower than in submaritima. Hind femora produced 
to an acute angle. Apical plate of abdomen small and narrow 
as in submarttema. Very likely a distinct species ; probably 
confused with C. tejonensis. 
Hab. Alum Rock Park, San José, California, May 3, 1902, 
2 3 (H. M. Ehrhorn). 
Ceratina Townsend, sp. n. 
2? .—Length 8 millim. 
Similar to C. neomexicana, Ckll., but differing by the 
yellower tint of the green, the darker wings, the smaller and 
closer punctures of the abdomen, and the closer and more 
uniform punctuation of the scutellum. It has been confused 
with C. dupla, Say, from which it differs by the much sparser 
punctuation of the vertex and front, the more pronounced rim 
of the metathoracic enclosure, and the darker wings. From 
C. Crewt, Ckll., it differs by its brassy-green colour, and 
especially by the sparser punctuation of the vertex on each 
side of the ocelli, this region in Crew? being very closely and 
coarsely punctured. 
Hab. San Rafael, Rio Nautla, Vera Cruz, Mexico, on 
flowers of Bedens and Verbesina, March 8 to 19, 9 9 
(C. H. T. Townsend). 
Tettigoniide. 
Oncometopia undata garry, subsp. n. 
g.—Length 11 millim. (to tips of closed elytra). 
Light ground-colour (#. e. all except the black) of head, 
thorax, and sides of abdomen lilac, except that the black 
markings are mostly narrowly edged with dull white, and the 
lateral spots on the scutellum are orange-vermilion ; the 
reversed A in black on the vertex is very distinct, and its
