AMARIN^E 291 



united with rubrica by Horn, is apparently peculiar, not only in 

 the absence of thoracic basal punctures, which character however 

 is sometimes manifest individually in other species, but also in the 

 small eyes and in the vestiture of the under surface of the anterior 

 male tarsi, described as densely pubescent in two series; this ves- 

 titure usually consists of two rows of subelevated membranous 

 plates. I have tried to identify the lost pallida Csy., from material 

 very kindly sent me with that object in view by Schott and Shoe- 

 maker, but am very doubtful of the indentity of the form above 

 described under that name. The eyes in this example se.em to be 

 larger, the antennae just a bit longer and the general form of the 

 body perceptibly narrower.* 



The two specimens representing texana Putz., above described, 

 hold together very well in general characters, but exhibit even 

 unusual variability in some special characters, such as the punc- 

 tuation of the pronotum and of the elytral striae; the tarsi, micro- 

 reticulation of the female elytra, general outline of the body an 

 the coloration throughout are, however, virtually constant. 



Celia acutangula Putz., was placed in synonymy with harpalina 

 by Horn, but on reading the original description, I am almost con- 

 vinced that this is a mistake, perhaps not quite so marked as the 

 association of pallida with subcenea, but probable nevertheless. 

 However, I have not seen anything that can strictly be identified 

 as acutangula and so place the species under harpalina, though dis- 

 claiming any responsibility for this course. 



The species near musculus Say, form a rather difficult study. 

 Virginica is larger, with very fine and finely punctulate striae and 

 flat intervals; it also has a larger head and relatively larger eyes. 

 Limbalis has shorter prothorax and elytra, larger head and shorter 

 hind tarsi; the hind tarsi are much less abbreviated or tapering in 

 limbalis, however, than they are in the comparatively minute brevi- 

 tarsis from the same region. The three species volatilis, fluminea 

 and vegrandis, separated because of the postero-lateral flattening 

 of the pronotum, similar to that of the terrestris series, are distinct 

 among themselves and quite different from musculus, but it should 

 be remarked that this flattening has but little systematic value 



* This, as well as about a dozen other unique types.-including those of Amara 

 marylandica and ferruginea, disappeared from my collection while temporarily at the 

 Cambridge Museum many years ago, and I have never been able to trace them.
