126 PHYTOPHAGA. 
Hab. Panama, Bugaba (Champion). 
Three examples, found in the forest-region of the “tierra caliente” of Chiriqui. 
These differ from the Amazonian specimen of D. cossyphoides, Guér., in the British 
Museum, determined by Boheman, and from a second from the same locality in 
the Baly collection, in having an additional row of impressions on the expanded 
margins of the elytra, the innermost (the ninth from the suture) being also much less 
coarse. D. panamensis is perhaps an extreme form of the rare D. cossyphoides, but in 
any case it is advisable to name it. To avoid future confusion, the description of an, 
allied South-American species is added below *. 
HIMATIDIUM. 
Imatidium, Fabricius, Syst. Eleuth. i. p. 345 (1801). 
Himatidium, Miiger, Mag. iii. p. 181 (1804) ; Boheman, Monogr. Cassid. i. p. 63. 
A Tropical-American genus containing numerous described species, four only of 
which inhabit Central America. Chapuis has noted an important character in this 
genus, viz. the more or less connate first and second segments of the abdomen, this 
peculiarity being common to the Hispide; Himatidium, in fact, forms one of the 
connecting-links between the families Cassidide and Hispide. 4H. limbatelium, Boh., 
from Mexico, was transferred by Baly to the genus Demotispa, see anted, p. 28.

* Delocrania latipennis. 
Obscure ferruginous, the outer portion of the disc of the elytra darker ; the margins of the prothorax dilute 
ferruginous, becoming flavous in front; the margins of the elytra dilute flavo-testaceous, ferruginous at 
the extreme base ; the antenne obscure ferruginous. Head with a few rather coarse punctures behind, 
depressed and canaliculate in front. Prothorax densely and rather coarsely punctured on the disc; the 
margins thickly covered with irregular fovex, each formed by two confluent punctures. Elytra 
considerably wider than the prothorax, subparallel, separately rounded at the apex; the disc coarsely 
and closely seriate-punctate, the suture and the fifth interstice, and the third interstice at the base, 
costate; the margins concave towards the base, with four rows of impressions—those of the innermost 
row (the ninth from the suture) exceedingly coarse and deep, and somewhat distant from each other, 
those of the three outer rows rather irregular, small, shallow, and closely packed, and separated from the 
inner row by a distinct space in which traces of another row of small impressions is visible,—the inter; 
spaces feebly transversely wrinkled.—Length 54 millim. 
Hab. Eicvavor (coll. Baly). One example.
