rudimentary crochets in a single row. No anal feet, their posi 

 tions indicated by slight elevations. 



Ncalyda kinzelella Busck. The mines of this species were 

 rarely found in the leaves of Pisonia obtusata where they tend to 

 produce a red discoloration, often bordering the mine, especially 

 when old. But very few living larvae were found. Head flat 

 tened, pale brown ; clypeus high, but not quite touching the ver 

 tical triangle ; labrum and clypeal sutures dark brown. Body 

 flat, joint 2 wide, 3 and 4 a little smaller, 5 to 1 1 about equal, .12 

 and 13 tapering. Segmental incisures well marked, the segments 

 a little angularly widened laterally. Cervical shield large, bi 

 sected into two triangular halves, blackish purple with a few 

 pale dots. Body whitish at the sides, with a broad diffuse pur 

 plish dorsal band, paired round white spots on joints 3 to 12, very 

 small on 5 and 12, the others large. Later this marking fades 

 and the body becomes all yellowish, only the cervical shield dark. 

 Feet bent in arcs like N. pi so nice, their number not observed, but 

 probably as described by Busck for the preceding species, those 

 of joint 13 lacking. The mine is on the upper surface of the 

 thick leaf, but the larva emerged by a hole on the under side at 

 maturity. 



Aprocerema crotalariella Busck. The larvae occurred on the 

 Crotalaria pumila growing near the sea. Head rounded, flat, 

 clypeus high, triangular, just touching the apical triangle ; whit 

 ish, eyes black in a dusky band which runs along the lower 

 angle of the lobe. Body short and thick, thickest centrally, the 

 ends distinctly smaller ; joint 2 small with large transparent cer 

 vical shield, a large black spot on the lateral angles and tiny pair 

 on the posterior edge subdorsally. Anal plate dusky. Body 

 white, translucent, food a narrow green line ; ^ glands in joint 9 

 very large, dark purple. A series of rounded patches of dark 

 vinous on joints 3 to 13 anteriorly, subdorsally before tubercle i, 

 stigmatally behind iii and spiracle, subventrally, small, behind 

 iv-(-v. Tubercles small, brown-black ; on thorax ia and ib separate, 

 iia-f-iib, iv.-fv ; on abdomen i dorsad 'to ii and rather approxi 

 mate, iv+v. Feet short, normal ; thoracic ones black except at 

 base. Tubercle vi with a slight vinous patch, vii with a patch on 

 one tubercle. Crochets of feet black on a circular planta, the 

 ring broken without and within. On joints 3 and 4 the stigmatal 

 vinous patch is before tubercle ii and covers also iv-fv ; on joints 

 ii and 12 the stigmatal and subventral patches are also united. 



Aprocerema sp. A single collected specimen. 



Gnorimoschema tcrracottella Busck. The larvae were found 

 feeding in the leaves of Iva imbricata, growing actually on the 

 ocean beach. The following are my notes : Mining about in 

 the thick fleshy leaves with a more or less distinct hole at the end 

 of the mine, sometimes the leaves more or less webbed up or the
