A NEW PSEUDOPHYLUID FROM JAMAICA 57 



twisted case. The moths which emerged hom the cocoons found on 

 bayberry were, in nearly aD cases, smaller than those from sweet fern, 

 measuring about 18 to 21 mm. in expanse in the former and 22 to 

 23 mm. in the latter. As a rule the basal area, within the scale ridge, 

 and median portion of the wing above and including the discal dots, is 

 much pciler and the posterior line more distinct than is the case with the 

 form from sweet fern. It seems quite probable that we have here two 

 distinct species, but if this is true, they are so close that more evidence is 

 needed before separating them. 



Acrobasis betulella Hulst. 



The nearly globular cocoons of this species, which have been suffi- 

 ciently described by Hulst (Trans. Am. Ent. Soc, XVII, 125, 1890), 

 were found in abundance on Betula alba and a good series of moths 

 was obtained from them. 



A NEW PSEUDOPHYLUID FROM JAMAICA 



(Orthoptera, Locustida) 

 By A. N. CAUDELL 



In a small lot of Orthoptera sent to the National Museum for determi- 

 nation by W. R. B. Robertson was a new species of Jamaicana. This 

 genus was described from Jamaica and is probably confined to that island, 

 the Meroncidius lativittata of Walker, a South American species listed 

 in this genus by Kirby, probably not belonging here. 



The above mentioned new species I have designated as Jamaicana 

 flava in reference to the genereJ yellowish color, which is very different 

 from the brownish cast of the other species of the genus. Structurally the 

 species of Jamaicana are very similar but the coloration of flava, a com- 

 paratively clear yellow, will serve to readily distinguish it from its browner' 

 relatives. The pronotal disk is also distinctive in color, being uniformly 

 piceous. The three species now known to surely belong to Jamaicana 

 may be separated as follows : 



KEY TO THE SPECIES OF JAMAICANA 



General color brownish ; pronotal disk not uniformly black. 



Pronotal disk concolorous with the lateral lobes . . uniformis Brunner 

 Pronotal disk marked longitudinally along the latero-dorsal margins with 



black subguttata Walker 



General color yellowish ; pronotal disk uniformly black . . flava a. sp.
