Hylotoma scapularis Kluo-. 



Yellowish, hku k-S])Ottfil, ( Jlcrpilhirliki- larvae iiearl)- ""4 inch long, feed on the 

 foliage of Anu'iiean elms in August. 



This species has hccii sliidied b_\' Mr j. ( .. Jack ol Jamaica Plain, aiul 



his description of tin- hir\ae ami account ot their habits follows : 



The full o;^ro\vn larvae have a ])retty (general resemblance to those of 

 11. [) e c t o r a 1 is Leach and are al)OLit i cS nun lung-. Head light orange 

 yellow, body somewhat llattish and light yellowish green in color. There 

 are six distinct rows of small closely adjoining black spots on the upper por- 

 tion of the boily e.xtcnding from the head to the anal segment. On ijach 

 of the fleshy projections on the sides of the segments, except the last, there 

 is an oblong dark sjjot ; but these spots above the two posterior pair of 

 true legs appear as two large somewhat triangular l)lack blotches. Above 

 the anal segment there is a large oval shajjed lilack spot. The legs are 

 black on the outer side, and the prolegs are marked b)- a dark brown blotch 

 on the outer side. The black legs and black l)Iotch on the anal segment are 

 the chief marks which distinguish this larva from that of H. pectoral is 

 in which the legs and anal segment are yellowish. The cocoons are of a 

 tlirty white or light brown color and average about i 2 mm in length. They 

 are composed of two walls, the inner being closely, and the outer looseh' 

 sjnin. 



The eggs are deposited along the margins of the leaves ot tlie common 



American elm ( 1-' 1 ni u s a m e r i c a n a) on which, the lar\ae feed. \'otmg 



lar\ae were found early in August and those oI)ser\ed attained full growth 



about the end of the month. Two males and many females were raised 



from these about the first of July billowing. 



Alder leaf beetle 



Clirv^^oiiiclti scalaris \a\c. 



A l)rilliant, liottle-green, o\',il lieetle about 's ini h long, with sihery white wing cov- 

 ers, the latter ornamented with several conspicuous green spots and with a im-dian jagged 

 stripe of the same color down the l)ack, feeds on the leaves of elm, linden, wUlow and 

 alder throughout the season. 



This, one of the prettiest of our naluc Ix-etles, sometimes becomes 

 excessively abuiulant, and l)r Hagen records an instance in 1884, when this 

 insect was ver\' aliundant on elms in Cambridge, and in 1S81 it was so
