244 PROCEEDINGS OF THE NATIONAL MUSEUM vol. us 



Remarks: The markings of this species resemble those of E. 

 vitticollis Blake from Puerto Rico except that the vittae on the pro- 

 thorax are longer. The graduated enlargement of the eighth to tenth 

 antennal joints is different from any of the other species. 



Luperosoma vittatum, new species 



Figure 19 



About 3.5 mm. in length, elongate oblong oval, shining, the elytra 

 finely punctate, in the male the fifth to eighth antennal joints enlarged 

 and the middle tibiae excised, pale yellow brown with a broad piceous 

 vitta on each side of prothorax and a broad piceous vitta nearly 

 covering each elytron leaving the margin and a narrow pale sutural 

 vitta. 



Head with the interocular space approximately half width of head, 

 occiput smoothly rounded, frontal tubercles well marked with a 

 median depression above, a narrow carina down lower front. An- 

 tennae in the male longer than half the body, third joint short and 

 compressed, not so long as second, fourth joint very long and slender, 

 fifth joint wider, sixth, seventh, eighth, much widened, ninth to 

 eleventh gradually diminishing in width, entirely dark piceous. Pro- 

 thorax only a little wider than long with the sides only slightly curved, 

 a faint transverse depression, sm-face shining, pale yellow with a 

 broad piceous vitta on each side. Scutellum pale. Elytra rather 

 depressed, a small basal callosity with an intrahumeral sulcus, surface 

 shining, finely and moderately densely punctate, pale yellow brown 

 with a broad piceous vitta extending nearly across the elytra, leaving 

 only a narrow pale vitta at the suture and the lateral margin pale. 

 Body beneath pale yellow brown with the tibiae and tarsi a little 

 darker, anterior tibiae in male enlarged, middle tibiae in male deeply 

 excised, anterior coxal cavities open, claws appendiculate. Length 

 3.5 mm.; width 1.4 mm. 



Type, male, USNM 66850, collected at Tegucigalpa, Honduras, 

 July 9, 1918, by F. J. Dyer, at 5400 ft. altitude. 



Remarks: The color pattern is similar to Phyllecthrus gentilis 

 Leconte, but the enlarged antennal joints (in this case the intermediate 

 instead of the terminal joints) and deeply excised middle tibiae in 

 the male are like those of Lwperosoma marginatum Jacoby and L. 

 nigrum Blake, both from South America. 



Luperosoma nigricolle, new species 



Figure 21 



About 3 mm. in length, oblong oval, shining, entirely dark piceous, 

 the antennae with thickened apical joints in the male (no female 

 examined) and excised middle tibiae, elytra rather rugosely punctate.
