BAGWORM MOTHS OF THE WESTERN HEMISPHERE 63 



Male genitalia. — (Fig. 257.) As described for genus. Eighth 

 tergite (fig. 202a) unusually large, elongate, faint notch at narrow, 

 posterior end. 



Case. — (Fig. 75.) "Length, 10 to 12.5 mm.; widest at the col- 

 lapsible mouth (2.5 to 4 mm.), thence tapering to a diameter of 

 about 1 mm. at the distal end. Many small fragments of vegetable 

 matter (principally bark) are embedded or partially embedded in 

 the silk; on the widened flexible mouth these fragments are larger 

 and less enswathed in the silk, than on the firm-textured, tapering, 

 tubular portion, where they scarcely project above the sm^face. 

 The case is probably carried upright, not suspended, by the living 

 larva" (Jones, 1926). 



Type.- — In the British IMuseum of Natural History. 



Type locality. — Georgetown, British Guiana. 



Recorded hosts. — "On bark of lime trees" (Jones, 1926). 



Distribution. — (Map 7.) Known only from the Guiana Coastal 

 Plain of British Guiana. 



Discussion. — Neither adult specimens nor larval cases of this 

 insect were available for study, but microscopic slides of the abdomen 

 and genitalia kindly were sent to me for examination by the British 

 Museum. As a result, the foregoing generic and specific descriptions 

 are taken largely from the original description of F. M. Jones (1926) 

 with some deletions and additional comments. 



10. Lumacrttf new genus 



Chalia, Clania, Cryptothelea, Eumeta, Oiketicoides, and Platoeceticus, in part, of 

 authors. 



Type of genus. — Eumeta hmsiliensis Heylaerts, 1884. 



Male. — Body moderately robust; densely hairy; bro\vnish to 

 dark fuscous. Antennae (fig. 373) broadly bipectinate, pectinations 

 long, slender, gradually diminishing in length toward apex, arising 

 apically at least on segments of outer half of antenna; sensory hairs 

 erect, very long, fine. Foretibia (fig. 175) with prominent epiphysis, 

 extending almost entire length of tibia; first tarsal segment doubling 

 second. Meso- and metathoracic tibiae completel}^ unarmed. Ab- 

 domen exceeding hindwings by nearly Yz its length. 



Wings (fig. 158) broad, usually evenly scaled, but apical third of 

 primaries hyaline in one species. Primaries 12-veined, relatively 

 acute apex, outer margin straight to slightly convex; R3 and R4 

 stalked; R5 usually connate, may be stemmed to R3+4; base of 

 medius either simple or forked ^vithin cell of both wings; M2 and 3 

 normally stalked; anal veins similar to that of Cryptothelea, spur of 

 3A usually prominent. Secondaries normally with 8 veins; Sc + Ri 

 and Rs connected by oblique crossvein either below or beyond apex 

 of discal cell; M2 and 3 either connate or stalked.
