is always more or less curved down near suture in abi'iiptus, while pabnii 

 has this fascia straight. The Nicaraguan cesopus seems to be very near 

 to palinii, but has the fascia curved down near the suture and in addi- 

 tion a yellow oblique line near apex. Clems crabi-onai-iiis Spin, which 

 it resembles also somewhat is a larger and more robust insect, with the 

 elytra very coarsly punctured. 



Hydnocera tricolor, new species. 



General form of discoidea, but larger and a little more robust, red ; elytra cover- 

 ing the abdomen^ a white fascia behind the middle ; apex black, clothed quite 

 densely with moderately long dark hairs. Antennae red, eyes prominent. Thorax 

 red, wider than long, apex strongly constricted, below the constriction strongly arcu- 

 ate, narrower at base than at apex, surface very densely not coarsely punctured. 

 Elytra wider than the prothorax at base, slightly narrowing to the apex, humeri dis- 

 tinct, apices serrate, broadly rounded, disk more, coarsely punctured than the pro- 

 thorax, apex more densely, given the surface a more scabrous aspect, red to about 

 the middle, apical third black, the red and black divided by a white fascia, the latter 

 with white hairs, the rest of surface with very short pale hairs intermixed with darker 

 and longer. Abdomen black, legs black except anterior femora which are red, the 

 middle and hind femora red with the apex black, sometimes nearly the entire femora 

 black. I>ength, 4-4.5 mm. 



Brownvsille, Texas. 



Types. — Four specimens in Museum of the Brooklyn Institute. By 

 the coloration this is easily known from any of the described species. 



Hydnocera omogera Horn. 



This species occurred at different places near Brownsville quite 

 commonly. It is as variable in size and in extent of the yellowish 

 white markings as discoidea. The spots in the smaller specimens are 

 as a rule more feebly developed than in the larger specimens, in the 

 latter there is mostly another yellowish white spot of variable size at 

 one third from apex. Specimens with an additional spot behind the 

 middle were also taken in Lower California with the typical form by 

 Mr. Beyer. 



Pelonium maculicoUe, new species. 



Form and size of Cregya vetusta Lee. ; testaceous, clothed with semierect pale 

 hairs, thorax maculate with black, elytra with base more or less black, on each side 

 about middle of disk three black spots, the two upper ones oblique and near the 

 suture, the two lower ones generally confluent, a broad black fascia, narrower towards 

 suture and irregular in outline, at about apical two fifth. Antennae eleven jointed, 

 half as long as the body in the male, shorter in the female, club longer than the pre- 

 ceding joints in the male, shorter in the female, last three joints black. Head 

 coarsely, densely punctured, black, with a longitudinal pale line, variable in distinct-
