mimic a Melipona bee of the same localities. In O. compressipes the elytra pass the 
tip of the third ventral segment; in 0. apicula they do not reach the end of the 
second segment, and are rapidly narrowed (both edges equally contracted) from about 
the middle.

4. Acyphoderes velutinus. (Tab. XX. fig. 19.) 
A. acutipenni affinis; differt elytris basi angustioribus, capite thoraceque nigris velutino-opacis, hoc solum callo 
elongato dorsali fulvo. In hoc genere angustus, niger ; antennis castaneo-rufis, scapo nigro, pedibus nigro- 
fuscis, femoribus quatuor anticis tibiisque subtus testaceo-fulvis; thorace subcylindrico, ante medium 
paullo rotundato-dilatato; elytris sicut in A. acutipenni flavo-testaceis, elongato-subulatis apice truncatis, 
subtiliter sparsim setifero-punctulatis, politis ; corpore subtus nigro, ventris segmento primo rufo-testaceo ; 
antennis brevibus, articulis 6°-10™ paullo latioribus, serratis.

Two examples, males, captured on flowers in a forest-clearing in the low hot Pacific- 
coast region. Narrower, especially across the base of the elytra, than A. acutipennis, 
and resembling an Odontocera rather than an Acyphoderes; but the elevated central 
callus of the thorax, the much-narrowed elytra, the strongly tumid club of the middle 
femora, and the form of the antennal joints, show that it belongs to the latter genus. 
5. Acyphoderes suavis. (Tab. XX. fig. 20.) 
Elongatus, gracilis, fulvescenti-rufus ; elytris fulvo-testaceis, circum scutellum pallidioribus ; pectore medio, 
femoribus 4 anterioribus supra, 2 posterioribus annulo mediano tibiisque macula, nigris; thorace breviter 
cylindrico-ovato, callo elongato dorsali alteris duobus parvis lateralibus, paullo elevatis, confertissime 
punctato, marginibus anticis et posticis aureo-pubescentibus ; scutello aureo-pubescenti; elytris basi sat 
angustis, segmentum secundum ventrale paullo excedentibus, gradatim angustatis, nec subulatis, apice recte 
truncatis, supra discrete sat conspicue punctulatis nitidis ; antennis brevibus, articulis 4°-7™ dilatatis 
serratis, 8°-11™ minoribus.
