282 MR. M. JACOBY ON COLEOPTERA [May 21, 
latter bifoveolate; elytra metallic green, rugosely punctured, the 
lateral and apical margin flavous. 
Male. Elytra with an elongate tubercle near the apex. 
Length 23 lines. 
Male. Head impunctate, entirely fulvous, with a small fovea 
between the antenne ; the clypeus transversely subquadrate, spar- 
ingly pubescent, labrum and palpi flavous; antenne two thirds the 
length of the body, black (the two penultimate joints in the female 
flavous), the basal joint flavous below, the third more than double the 
length of the second; thorax twice as broad as long, the sides but 
slightly rounded before the middle, the surface impunctate, fulvous, 
shining, with a deep fovea at each side; scutellum flavous; elytra 
dark metallic green, the disk transversely wrinkled and rugose, with 
some narrow longitudinal costz and a strongly raised longitudinal 
tubercle near the apex, the lateral margin narrowly, the apical one 
more broadly, flavous ; underside and the upper edge of the femora 
and tibis as well as the tarsi entirely black. 
San Esteban. 
Allied to D. ambitiosa, Erichs., D. puncticollis, Baly, and several 
other species, but differing from all in the metallic elytra and the 
different system of coloration, especially in the black underside. 
DIABROTICA VARICORNIS, Nl. Sp. 
Fulvous ; intermediate joints of the antenne black ; thorax bi- 
foveolate ; elytra finely punctured, a ring-shaped mark at the base 
and another semilunate one near the apex as well as the breast 
black. 
Length 3 lines. 
Head impunctate, fulvous; labrum black; antenne elongate, 
extending to two thirds of the length of the elytra, fulvous, the 
fourth and the following five joints fuscous or black, the second 
joint short, the third slightly longer ; thorax impunctate, nearly as 
long as broad, the surface with two deep foveee; scutellum fulvous ; 
elytra finely and closely punctured, the base of each with a regular 
black ring-shaped mark, another semilunate similar mark, open at 
its posterior portion, placed near the apex. 
San Esteban. 
Closely allied to D. inequalis, D. haroldi, Baly, and D. biannu- 
laris, but differing from all these species im the fulvous head and 
legs ; from D. delineata, Jac., a still more closely allied species, the 
present insect may be separated by the much longer antennz, which 
have their joints (with the exception of the second and third) much 
more elongate and also differently coloured, and by the elytral 
broader markings which in D. delineata are very thin and fine. 
DIABROTICA OBSCURO-MACULATA, N. Sp. 
Subdepressed, obscure testaceous ; antennze long, the third joint 
elongate ; thorax finely punctured, transversely depressed ; elytra 
closely punctured, the interstices subrugose, the suture anteriorly,
