it has been recognized from Mexico by Mr. Jacoby in Biol. Cent. 

 Am., vol. VI, pt. I, p. 193, and is figured on tab. X, fig. 1 as ccncivcntris. 

 It is not a Lina but a Plagiodera, at least, it is recorded under the 

 latter genus by Mr. Jacoby. 



Zygogramma estriata new species. 



Reddish-brown, elytra flavous with subsutural vitta confluent with the 

 narrow sutural vitta, the former not reaching quite to base and of rather ir- 

 regular outline and a number of relatively large, reddish-brown spots, which 

 are surrounded by moderately large punctures. Head sparsely punctate. Pro- 

 thorax strongly transverse, apical angles rounded ; sides feebly arcuate ; basal 

 margin moderately arcuate ; surface finely alutaceous with very few punctures, 

 which are more numerous and coarser towards the lateral margin. Elytra 

 convex ; flavous with sutural and subsutural vitta confluent and numerous spots 

 of variable shape reddish-brown, the punctures between these spots brown and 

 not densely placed ; the regular row of submarginal punctures absent ; epi- 

 pleurse pale, except the exterior margin which is reddish-brown. Body be- 

 neath reddish-brown with very faint metallic tint ; metasternum and abdomen 

 sparsely punctate with moderately large punctures. Length 5.75 mm. 



Huachuca Mts., Arizona. 



This species is apt to be taken for a var. of my Z. arizonica, from 

 the same region, in which the irregular dorsal vitta is broken up into 

 spots. It differs, however, from that species by having a pale elytral 

 epipleura and the absence of the regular row of punctures near side 

 margin, which latter is present in all our species of Zygagramma. 

 The form is also a little shorter and more convex than in Z. arizonica. 



Phyllobrotica vittata Horn. 



My series of this species which are mostly from New York and 

 New Jersey, show more variation than indicated by Dr. Horn from 

 his four specimens in the remarks following the description. 



The head above is generally black and in front yellow, but occa- 

 sionally entirely yellow. The elytral vitta is more or less distinct or 

 entirely absent and the ventral segments black, or the segments black 

 with yellow margin, sometimes entirely yellow. The males have the 

 antennal joints stouter than the females and the outer joints distinctly 

 dilated. 



Agelastica alni Linn. 



Three specimens of this European species were collected by Mr. 

 G. P. Engrelhardt on his office window of our Museum.
