148 MEMOIRS ON THE COLEOPTERA 



Langurites superciliatus n. sp. Male with the entire under surface and 

 legs pale flavo-testaceous, the head entirely testaceous above, the pro- 

 thorax and elytra colored as in the preceding species. Female with the 

 entire under surface and coxae pale, the legs throughout deep black, the 

 femora all gradually and nubilously pallescent basally, the upper surface 

 colored as in the male, except that there is no trace of a medial pronotal 

 vitta and that the marginal black stripe is much reduced in width; the 

 scutellum is blackish, but the entire basal part of each elytron is testaceous, 

 the pale tint very gradually and nubilously fading out behind but trace- 

 able along the middle of each elytron almost to apical third or fourth. 

 The antennae are in great part missing in the male, but they are pale at 

 least at base; in the female they are deep black throughout, extending to 

 basal fourth of the prothorax, with the seventh joint intermediate in 

 thickness between the sixth and the basal joint of the club, which increases 

 very little in width thence to the end; superciliary ridges much narrower 

 and more abruptly and strongly tumid than in apiciventris. Length 

 (cf 9 ) 11.5-11.7 mm.; width 2.2-2.3 mm - Florida. 



In the general proportion of the parts and in sculpture these two 

 species are much alike, but superciliatus is shorter and relatively 

 stouter. The last ventral of the female differs from that of the 

 preceding species in having the rather strong punctures well separ- 

 ated toward the sides of the segment but fine and sparse medio- 

 apically ; in the male the last ventral has a small, broadly and evenly 

 parabolic notch which is distinctly wider than deep. The differ- 

 ences in coloration between the male and female as detailed above 

 are extraordinary, and I cannot say at present whether they are 

 characteristic or in part fortuitous. 



Languria Latr. 



The following species is allied to convexicollis Horn, and possibly 

 also sanguinicollis Chev., apparently agreeing more nearly with the 

 latter in elytral sculpture, but differing among other ways in the 

 coloration of the head : 



Languria interstitialis n. sp.- Form stout, nearly as in convexicollis 

 and of about the same size and coloration, polished, deep black throughout 

 the body, legs and antennae, except the prothorax, which is clear rufous 

 above and beneath, the head generally more or less rufescent basally 

 above and below, sparsely but distinctly punctate, more coarsely on the 

 epistoma, the epistomal suture perfectly straight; lateral marginal edge 

 strongly cariniform; antennae with the first of the six joints of the club 

 small, polished like the preceding joints and but little thicker, of the same 

 shape as the second club joint but only half as wide; prothorax somewhat 

 longer than wide, the sides distinctly arcuate, becoming slightly oblique 

 and straighter only near the base; surface convex, very minutely, re-
