NORTH AMERICAN LEPIDOPTERA. 87 



A single specimen only is before me at present ; but the insect is 

 represented in several of the collections, and by more than one speci- 

 men. I have had several for examination, and found no variation. 

 The insect differs a little in habitus from the generic type ; but is 

 correctly referred I think. The anterior tibia is as described for the 

 genus, save that there is a short inner as well as a longer outer claw- 

 like spine. The markings are ren>arkably neat and clean, and though 

 there is nothing striking, yet everything is well defined. 



Oxyciieinis perruiidis n. sp (PI. vi, iig. 6)— Ground color white, with 

 a faint yellowisli liiifje, more or less clothed with luteous scales, which makes 

 the appearance darker or lighter as the case may be. Head and thorax concol- 

 orous, immaculate. Primaries with all the markings obscured and incomplete. 

 The basal and t. a. lines ai'e marked by blackish dots on the costa only: the t. p. 

 line is single, brown, slender, even and obliquely outcurved over the costal re- 

 gion, with small creiiulations, and parallel with the outer margin below the cell. 

 In some specimens the line is visible only through the costal region. S. t. line 

 obsolete, marked only on the costa by a dusky patch in the s. t. space. Fringes 

 white. The claviform is indicated in one specimen by a few black scales. The 

 ordinary spots are vaguely traceable as slightly paler macula of moderate size ; 

 but not defined in any way. Secondaries white, shining, with a faintly marked 

 outer border, the fringes white. Beneath white, immaculate, the primaries with 

 a faint yellowish tinge. Expands 19-20 mm. ; .75-.80 inches. 



Hab. — Nueces River, Texas ; Southern Texas. 



I have seen quite a number of this little species, and have had 

 specimens for some time. It is easily recognizable, and is remark- 

 able for the very much abbreviated anterior tibia, which is shorter 

 than the curved claw at its tip, and much shorter than the first tarsal 

 joint. The insect combines in its appearance the features of an 

 Acontiid, and of an Heliothid. 



Oxyciieinis nivali!« n. sp. (PI. vi. fig. 5)— Ground color white, the head 

 with an ocherous tinge in front; disc of thorax and primaries with a faint gray- 

 ish tinge; secondaries snowy, immaculate. The primaries are also immaculate, 

 only the faintest trace of an oblique median shade being visible. Beneath, 

 primaries blackish, the margins white, the secondaries pure snow-white. Ex- 

 pands 26 mm. ; 1.05 inches. 



Hah. — Texas. 



This is another easily recognizable form. The anterior tibite are 

 short and broad ; but not so much abbreviated as in perfundus, and 

 there is a small inner claw, which is not present in the former species. 

 The type is a perfect female from Mr. Neumoegen's collection. I 

 think I have seen another in the National JNTuseum material.
