44 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 7 



irregular reticulated pattern of rust-colored blotches (pi. 6, fig. 82). An 

 individual from La Libertad, Ecuador, has the rust-colored pigment re- 

 placed by sooty color. Base of palpi dark, appearing tucked in at its 

 insertion. 



Elytra are neatly fringed on their external margins. Median elytra 

 oval, with a slight excavate anterior margin. The surface is covered 

 with minute, chitinous tubercles, with a broad squat base and a slender 

 stalk. Scattered irregularly over the surface but leaving a pale area over 

 the elytral attachment are rust-colored blotches. Under high magnifica- 

 tion they are seen to be mesh-like because of clear, cellular areas among 

 them (pi. 6, fig. 78). 



Notopodial setae are fine, short, serrated. They number about 30 in 

 a median parapodium, and do not extend distally beyond the neuro- 

 podium. Neuropodial setae are heavier, longer, including about 20 

 supraacicular and over 50 subacicular in a median parapodium. Dis- 

 tally they have a minute subterminal tooth, but the inferiormost setae 

 tend to be entire (pi. 6, fig. 81). This weakly bifid condition of the 

 neuropodial setae agrees with the condition shown by Augener, and is in 

 contrast to the condition shown by Kinberg for L. caeruleiis from 

 Brazil (1910, pi. 4, fig. 16). The first 2 or 3 neuropodia have setae 

 that are distinctly bifid, those of the first parapodium are more dis- 

 tinctly toothed and have a longer serrulated blade (pi. 6, fig. 79) than 

 those in the following segments ( pi. 6, fig. 80 ) .
