NO. 1124. RETISIOX OF THE MELANOPLI SC UDDER. 43 



plate nearly quadrate, tapering very slightly, the outer angles slightly 

 produced, and the posterior edge with a median, triangular, pointed 

 extension, a third as wide as the extremity of the plate and longer 

 than broad; furcula consisting of a pair of attingent, depressed, rather 

 stout, scarcely tapering, blunt-tipped fingers, fully half as long as the 

 suprannal plate and slightly upturned at the tip ; anal cerci very simple, 

 being slight conical projections^ tapering mostly in their basal half, the 

 tip blunt, the whole not so long as the disk of the supraanal plate, 

 omitting its apical extension. 



Length of body, male, 16.5 mm., female, 23 mm.; antennae, male, 

 female, 8 mm. ; hind femora, male, 10 mm., female, 12.25 mm.

2. PARAIDEMONA MIMICA, new species. 

 (Plate III, fig. 10.) 



Yellowish testaceous, heavily banded with black, especially on the 

 sides, and more markedly in the male than the female. Head with 

 the interspace between the eyes very narrow, especially in the male, 

 the fastigium between them sulcate, narrowly in the male, the sulcation 

 continuing so as to be subcontinuous with that of the frontal costa, 

 which is sulcate in its whole extent, equal, and broader than the inter- 

 space between the eyes. Prouotum punctate as in P. punctata, and as 

 there a glabrous spot free of punctuation occurs on the prozoua at the 

 summit of the lateral lobes. A black stripe, sometimes wanting or 

 feebly fuscous in the female, begins at some point on the fastigium and 

 continues backward, broadening on the head so as to include nearly 

 the entire vertex, and crosses the pronotuni as a broad mediodorsal 

 band, as broad as the length of the metazona, or in the female even 

 broader; it is sometimes obscure or wholly obsolete in the female, while 

 in the male it is always distinct, at least on the prozona, and generally 

 continues, though narrowed, over the rneso- and metanota. The lat- 

 eral band, generally rnfo-piceous, is still broader and is sharply defined 

 above and below, often uninterrupted on the metazona in the female, 

 where it widens so as to include behind the whole of the thoracic pleura 

 (excepting the episterna) and the sides of the first four abdominal seg- 

 ments; above it is more or less distinctly accompanied in the female by 

 a testaceous stripe. The dorsum of the abdomen of the female lacks 

 the double series of oblique lateral dashes found in P. punctata, or has 

 them very feebly marked. Hind femora yellowish testaceous, the outer 

 face growing darker below, giving there a broken irregular blackish 

 stripe ; hind tibiae glaucous, the pallid spines black tipped. Supraaual
