JASSIDAE. 
Dorydium maculatum, n. sp. 
Light cinereus with brown or fuscous on vertex, pronotum 
and elytra. Vertex at tip, sinuous lines on the face, clypeus, 
coxae, pectus and spots on the legs black. Length of female 
5 m. fn.; male 4 m. m. 
Head with eyes scarcely wider than the pronotum, eyes large, vertex 
narrow, about three times as long as width between eyes, flat faintly 
impressed on median line and with slight depression on disk and next the 
tip. Apex acute, slightly upturned, front rather strongly keeled at tip 
becoming convex at clypeus. Clypeus with parallel sides nearly twice as 
long as wide; lorae longer than wide, outer margin nearly semi-circular 
not reaching margin of cheek. Genae broad rather deeply sinuate behind 
the eye. Rostrum shorter than clypeus. Pronotum strongly arched in 
front, lateral margin short, hind margin slightly concave, surface minutely 
striated or faintly rugose on central part, not carinate; scutellum with 
apex very acute, length scarcely equal to the width at base, elytra opaque 
except for small sub-hyaline areas in first, second, third and fifth apical 
cells and anteapical and discal cells. Clavus with two veins situated 
rather close together the outer one remote from claval suture; corium with 
five apical, one ante-apical and two discal cells; the costal veins reflexed; 
the vein below anteapical cell expanded into a minute cellule. 
Color cinereous or somewhat stramineus with light brown markings on 
vertex, forming a large discal spot in front of middle, two marginal triangu¬ 
lar spots, and central transverse band with more definite spots toward the 
margin, and a central line running backward, another brownish band 
between the eyes with darker spots toward the center, pronotum with three 
indefinite brownish longitudinal stripes, a pair of dark brown slightly 
infuscated spots on anterior margin, the outer longitudinal stripes and 
the spot behind the eye fuscous; scutellum with a basal median spot and 
anteapical arch broadening at margin, fuscous two spots in basal portion 
of clavus, two on the disk, and sutural line and the reflexed costal veins 
and spot on inner apical veinule dark fuscous or blackish. Face with the 
tip of vertex black; face with somewhat broken sinuate lines each side, 
fuscous or blackish lower part of face including most of clypeus and 
cheeks below the lorae black, and propleural spots and spots on the 
pectus, tarsal claws on front and middle feet and a series of spots at base 
of spines, apex of tibia, apex of tarsal joints and claws of hind feet black. 
Line on the inner side of hind tibia black. All marks are more intense in 
the male but color pattern is identical. 
Genitalia: Last ventral segment of female about as long as the pre¬ 
ceding, hind margin not produced, slightly sinuate, ovipositor exceeding 
the pygofer by about its length and tipped with reddish; the male 
valve hidden under last ventral segment, plates and pygofer very short, 
the former thick narrow and reaching the lower apex of pygofer. Pygofer 
obliquely truncate, margins meeting ventrally in an obtuse angle. 
Described from a series of five specimens collected at Los 
Amates, Guatemala, by Prof. J. S. Hine, Jan. 17, 1905. It is an 
interesting addition to the Dorydine fauna differing quite dis¬ 
tinctly from the European representatives of the genus. 
Scaphoideus scalaris Van D. 
Mazatenango, Feb. 3d. Originally described from California 
the species is now known from Washington and New York
