qiient reports of piuoapple fields turning yellow in spots, and when 

 the plants were npi'ooted the soil was fomid to contain many white- 

 grubSj which turned out to l)e the larvae of this species. Coffee 

 groves are subject to attack of tliis May-beetle due to the fart that 

 they are grown under shade of certain forest trees, the foliage of 

 which is much relished by tlie beetles. After feeding, the beetles 

 descend to the coffee trees beneath the larger shade trees, burrow 

 doAvn into the soil in great iininViers at their bases and tliere deposit 

 the eggs. Naturally, the eggs are found, and the wliite-grubs that 

 hatch from them do the damage, in whatever locations the beetles 

 descend into the groiuul. One of tlu^ principal shade tr-ees of coffee is 

 the '"gnama" {Inga lauri)ia), and its foliage is often bjuUy damaged 

 by May-beetles of this species. Mr. Van Dine in a note of Ai^ril 27, 

 1912, reports tlie finding of seventy-four ]May-beetles at 1lie base 

 of a "gnama" tree in a coffee grove, and one hundred aiul sixteen 

 beetles at the l^ase of one coffee tree near by. It is not uncommon 

 to find thirty or more May-beetles of this species at the l)ase of a 

 coffee tree. The beetles do not feed \\]^ou the coffee foliage, but 

 that fact does not. liowever. in-event the larvae from attacking the 

 coffee roots. 



In sugar i>lantations. tiiis species has been known to do local 

 damage, sometimes even extensive damage, particularly in tlie For- 

 tuna and Aguirre districts, and at Hiuuacao, Fajardo, and Cano- 

 vanas. Xo doubt there has been damage in otliei- districts, not so 

 far reported. Outbreaks to an injurious extent seem however to he 

 sporadic, and in none of tlie infested districts mentioned has attack 

 been so severe as to necessitate the continued employment of women 

 and boys to gather the grubs and beetles, as is done in the (iuaniea 

 district in the casi^ of thi^ preceding si)eeies. 



I'lll-: l>KETLE. 



The adult very closely rc>eml)h s that of the lU'eceding species, 

 but is iisnally somewhat greater in size (averaging 1 to 2 millimeters 

 more in length), dai'ker in color, and with the surface somewhal 

 polished. In these characters it varies greatl.w It is at once dis- 

 tinguishalilc. in the male, by the sexual chai-acters given in the table: 

 i. p.. ill the adnate armatures nf the male genitalia i'ciiio- spatiilate 

 at the tip w hei(^ ill /'. rniHliiici they are hit'urcate. 



Like the prec('(liiiu-. the adult of this species may he foiuul in 

 the Held fliiring eight to nine months oi' the year. It ap|)eais the 

 latter pai't of Fehniary to early .March, and disappears (lining .\o- 

 A'ember. Stragglers are occasionally found in the wintci' months.
