482 ENTOMOLOGICAL SOCIETY 



Body slender, segments monilif'orm, joint 12 smaller, sharply noniliform, 

 13 small and slenderer. Thoracic feet large, pale; abdominal ones very 

 small, slender, close together on joints 8, less so on joint 9, more separate 

 on loand remote on 7 ; a longer pair on joint 13; crochets few in a circle. 

 Setae i moderate, ii minute, posterior, iii small, iv large, substigmatal, a 

 little posterior; a tiny seta (v?) just above vi ; vi large, somewhat anter 

 ior; vii small on base of leg; viii within. On thorax iii and v are pre 

 sent. Translucent whitish green, food dark green. Anal plate shield- 

 like, rugose, blackish on the lateral edges. Dorsal vessel with whitish 

 edges. 



At maturity the larva is pale green, a dorsal, a broad geminate 

 lateral and faint subventral dark red lines. Pupation in a delicate 

 web remote from the leaf. The pupa resembles a seed, a point 

 in front, cases nearly reaching the cremaster. 



Metriochroa psychotriella Busck. The larva mines the leaves 

 of the u wild coffee " {Psychotria undatd] as described by Busck. 

 Head rounded, prominent, the labium a broad, even band to base 

 with small spinneret and palpi at tip ; labrum moderate, clypeus 

 a broad bancl extending to vertex and not narrowing ; lobes -full ; 

 antennae colorless ; no ocelli ; a few rudimentary setae ; translu 

 cent yellowish. Body flattened moderately, round, tapering 

 much behind, not so before; segments moniliform. Joint 2 

 wider than head, without shield ; 3 still wider (setae ia and ib 

 fairly distinct on joints 3 and 4) ; joints 4 to 10 about equal, n 

 to 13 tapering, the latter divided by a strong suture. No plates ; 

 no dorsal setae on the abdomen. Skin finely granula, not annul 

 ate nor creased. Thoracic feet absent, represented by three 

 pairs of smooth circular plates. Abdominal feet represented by 

 narrow concave ellipses containing brown spicules on joints 6 to 

 10 and a terminal median patch on joint 13 posteriorly with a seta 

 on either side. Color translucent whitish with a yellow tint. No 

 setae except on the thorax and joint 14. 



Marmara guilandinella Busck. The larvae mine the stems 

 of Guilandina bonducella under the epidermis of the bark, a 

 linear, widening, irregular, wavy and recurving mine, white at 

 first with central dark line of frass ; later turning brown. 



Lithocolletis verbesinella Busck. The larvae form mines on 

 the under side of the leaves of Verbesina virginica, blotch-like, 

 a little swollen and red above, membranous below, finally sewed 

 up into longitudinal furrows. A white cocoon slung in the ho- 

 low of the mine. The larva has the head flattened, the vertex 

 under joint 2, clypeus high and not narrowing much till above 

 the middle, nearly touching the vertical triangle ; mouth prom 

 inent, brown, ocelli black. Body whitish, no marks.
