middle. First abdominal segment nearly as long as tlie 

 second and third united, the apex distinctly dilated; the 

 following segments are not compressed, distinctly broad 

 compared witii those of Campoplex. 



I refer this species to Zachresta because the spurs, although 

 longer than usual, are still distinctly shorter tlian i\\Q meta- 

 tarsus ; in the allied genus Echtlironomus, Foer., they are 

 described as "very long, scarcely shorter" than it. The 

 only difference between tliis species and Campoplex of much 

 importance lies in the abdomen not being strongly compressed, 

 the latter genus having also the metanotum longer and more 

 or less areolated. 



Anomalon Binghamij sp. n. 



Black ; the face, clypeus, mandibles, malar space, a broad 

 line on the lower third of the inner orbits, tegulse, and under- 

 side of antennal scape lemon-yellow; the abdomen (except 

 the top of the basal two segments) rufo-ferruginous ; the four 

 front legs fulvous, tinged with yellow, their coxa? and tro- 

 chanters yellow ; the hinder legs rufous the coxte and 

 trochanters black above, the former broadly yellow in the 

 middle below, the apical third of the tibise black ; the apical 

 joints of the tarsi tinged with yellow. Wings hyaline, tinged 

 w^ith fulvous, highly iridescent; the stigma testaceous, the 

 costa and nervures black, c? •

Sikkim. 



Head covered with white hair ; the face strongly punc- 

 tured, the punctures large, clearly separated ; the front 

 stoutly obliquely reticulated ; the vertex strongly deeply 

 punctured. Mesonotum strongly closely punctured, the 

 punctures running more or less into each other, the apex 

 stoutly transversely striated. Scutellum roughly reticulated, 

 depressed broadly in the centre. Metanotum much more 

 widely reticulated, slightly broadly depressed in the middle, 

 as are also the metapleurfe. Propleurte stoutly striated, 

 obliquely above, longitudinally below ; the upper part 

 distinctly punctured. Mesopleurge above longitudinally 

 coarsely reticulated ; the apex smooth, bare, below the reticu- 

 lated part, the re^t punctured, the punctures clearly separated, 

 each having a black hair. Flagellum of antennae rufo- 

 testaceous, the basal half black above. 



Allied to A. tincti'penne, Cam., from the Khasias. The 

 present species may be known from it by the stoutly reticu- 

 lated front : in tinctipenne it is striated rather than reticulated.
