workers, and I did nut find the nest or ascertain the kind and 

 importance of the honey they make. Tlie j^t'iiorie name is almost 

 too much like Trijonia of C'onchulogy, but a.s the |)r<»uuiii-i:iti..n 

 differs it can remain . 



2. T. LKiATA. — O lilaeliiish ; abdominal sogmentij margined 

 with oehreous. 



Inhabits Mexico. 



Body brownish-black, hairy; antennae beneath, particuhirly 

 the basal joint, anterior half of the anterior orbits, line distin- 

 guishing two lobes of the hypostoma and mouth, dull yellowiMh : 

 wings slightly tinged with fuliginous, particularly toward.s the 

 base ; nervures of the cubital cellules like those of the lilinrata 

 nob., but the first one is much more distinct : tcrgum shortly 

 hairy j posterior margins of the segments oehreous : feet dull 

 bonoy-yellow ; tip of the posterior tibiae and base of the first tar- 

 sal joint black. 



Length about two fifths of an inch. 



Of this I obtained but a single specimen, which is a worker. 

 It is widely different from the preceding species, particularly in 

 being hairy, and is much larger and of a somewhat different 

 habit. I have carefully compared it with Latreille's descriptions 

 and figures of Milipona [416]./'"i'S'f lUig., scukthiris liatr.,/<i«- 

 ruita Latr., {)ihrruj)ta Latr., and other species as given in Hum- 

 boldt's Zoological Observations j and even should it be referred 

 to that genu.s notwithstanding it.s denticulated mandibles,- 1 have 

 endeavored to draw out such characters as may distinguish it 

 from them. Latreille, however, says of Melipomi, " Mandibles 

 sans dentelures apparentes " which entirely includes this speciei', 

 although it agrees in habit.
