MICROLEPIDOPTERA OF JUAN FERNANDEZ ISLANDS — CLARKE 85 



Another widely distributed pest, the notorious "potato tuber- 

 worm," may be expected wherever potatoes are shipped commer- 

 cially. 



Echinoglossa, new genus 



Type-species: Echinoglossa trinota, new species. 



Antenna simple in female, finely serrate in male, nearly as long as 

 forewing, basal segment without pecten. Labial palpus upturned; 

 second segment somewhat roughened beneath with brush expanded 

 apically; third segment about as long as second, smooth, acute. Head 

 smooth, ocellus small, posterior; tongue well developed, thickly scaled 

 basally. Hind tibia slightly roughened above with long, slender scales. 

 Forewing smooth, apex gi-eatly produced, attenuated; 12 veins; 2 

 remote from 3 ; 4 and 5 stalked, about as far from 3 as 3 is from 2 ; 

 6 from upper angle of cell, connate with 9, to termen; 7 and 8 stalked 

 out of 6; 9, 10, and 11 about equidistant. Hindwing with 8 veins; 

 2 distant from 3; 3 and 4 connate; 5 curved, well separated from 

 4; 6 and 7 parallel; crossvein between 7 and 8 present near base. 



Male genitalia typically gelechiid. Dorsal and ventral elements 

 of harpe present. Gnathos present. Aedeagus unarmed. 



Female genitalia with well-developed signum. 



In the large family Gelechiidae relatively few genera have veins 

 4 and 5 stalked in the forewing as in this new genus Echinoglossa. 

 Of the genera with this character that I have examined, Agathadis, 

 Alsodryas, Dissoptila, Eristhenodes, Molopostola, Synactias, and 

 Tholerostola all are South American. The Indian Ischnophenax and 

 African Epenteris approach the South American genera by having 

 connate veins 4 and 5 but apparently the stalked condition of these 

 veins is largely an American development. 



Echinoglossa is perhaps most nearly related to Dissoptila but in 

 the latter genus, vein 6 of forewing is separate from the stalked 

 veins 7 and 8 and the apex is not produced as in the former. Also, 

 in the hindwing, veins 4 and 5 are connate in Dissoptila, separate in 

 Echinoglossa.

Figures 85-88 



Alar expanse 9-10 mm. 



Labial palpus sordid white; second segment shaded with dark 

 gray in apical half; third segment with a dark gray, anterior, longi- 

 tudinal line. Antenna dark gray with paler annulations. Head, 

 thorax, and ground color of forewing cinereous; head and thorax 

 with slight infuscation; base of costa narrowly fuscous; stigmata
