What is quite evidently the larva of this species was col- 

 lected from the same grass at the same time. Head characters 

 are similar, the general body color is soiled yellowish white, the 

 frons is marked by fuscous arcs and the eyes are blackish 

 fuscous; each segment of the abdomen above from the second 

 to the sixth is bordered by four rectangular black points which 

 are separated from each other by a median white line which 

 runs the length of the abdomen, and also extends forward as a 

 broken stripe over thorax and extends forward on the vertex 

 where it widens anteriorly and fades out near the apex, and by 

 two rows of whitish spots either side of the middle line. 



Dictyophara microrhina Walk. 



Adults of this species were taken in considerable numbers 

 from beach grasses at about the level of high tide. There was 

 no evidence of their being adapted to complete submergence 

 and as the species occurs on rank lowland grasses away from 

 the coast there is evidently no restriction to the aquatic habitat. 

 The species, however, illustrates the persistence of an insect in 

 following its food plant into conditions of life that must be 

 quite dissimilar from those under which it first formed the 

 association. 



Acanalonia pumila VaiiDuzee. 



This species was taken in the same association as the Dic- 

 tyophara microrhina and there is apparently the same or very 

 similar adaptation to. the condition prevailing at the high tide 

 line. Among the examples taken were a number which instead 

 of the normal green color were of a dull straw color closely 

 resembling the color of the dead leaves of grass. No evidence 

 as to the place of egg deposition or concerning the early stages 

 was secured but it would seem very probable that the eggs 

 must be laid in such positions that they would be exposed to 

 the submergence at periods of unusual high tide if not in ordi- 

 nary high tide.
