JAvSSIDAE. 



Dorydium maculatum, n. sp. 



Light cinereus with brown or fuscous on vertex, pronotuni 

 and etytra. Vertex at tip, sinuous lines on the face, clypeus, 

 coxae, pectus and spots on the legs black. Length of female 

 5 m. ni. ; 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 fjygofcr by about }4 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.
