134 ORDER COLEOPTERA. 



Adimonm . ( Plate xiv, fig. 4.) 



Color yellowish green : head and its appendages black. A dejiression and two eminences 



behind the antennse. The three first antenna; yellowish green ; on the outer side, 



brown ; the remainder dark brown or black : pectus black : abdomen yellowish 



green. Thorax greenish yellow predominating, innnaculate : two slight indentations 



•on each side, with a slight lateral ridge or dilatation Elytra pale green, marked with 



eleven black rather quadrangular spots : most of them have their angles rounded, so 



as to approach an oval form ; the basal spot is common to both elytra. Legs black : 



upper half of the thighs greenish. Length one-fourth of an inch. 



It will be evident from the above generic and specific descriptions, that this insect is 



neither a Cralemca, Lema or Haltica, and probably uot an Adivionia : it belongs, however, 



to the vast family Galerucidje. It is rather common in September and October on the 



asters and solidagos. Either the descriptions within my reach are faulty, or else it has not 



been described. 



Lema trivittata. 

 Rufous : thorax and head rulbus ; the former punctured transversely at its base, and 

 marked with two black dots. Elytra marked with longitudinal black stripes, the 

 middle sutural : punctures arranged in lines. Antennje black ; first joint rufous : 

 lower tibia and tarsi black. One variety more rufous, and marked with wider stripes 

 and larger dots upon the thorax : sometimes the dots are absent. 

 Resembles the striped cucumber-bug. 



Galeruca vittata. 

 Color yellow : head black. Elytra marked with three black longitudinal stript s, including 

 the sutural one : abdomen black ; forelegs mostly of that color : knees and feet o 

 the other legs black. 

 This insect is troublesome to various vines, anH especially to young cucumber vines 

 when not of a vigorous growth. The best remedy is to secure a strong and rapid growth : 

 other remedies, which are more or less successful, are, washing the plant with offensive 

 liquors, or sprinkling them with strong-scented powders. Tobacco in its various forms, 

 whale-oil soap, etc. are all more or less useful. 



Galeruca calmariensis ( Lin.). ( Plate xii, fig. 12.) 



This is a European insect, which has been introduced in o this country alx)ut Baltimore. 

 It is destructive to the foliage of the elm. It is about one-fourth of an inch long, and is 

 described by Mr. Stephens as follows : ' Oblong-ovate ; i:bovc testaceous, deeply punc- 

 tured : crown, furrow on the thorax, scutellum, a dash in the elytra, 1 reast find ba^'c of 

 abdomen, black ; apex of the abdomen and base of the antennae testaceous.
