isphere with the exception of the Old and New Mexican genus 

 Lconidia Ckll. (containing two species) from which Hornia 

 may be separated by the following table : 



1. (2) Antennae of 10 articles, abdomen partly membranous, claws 



unarmed Hornia Riley. 



2. (i) Antennae of 10 articles, abdomen entirely subcorneous, claws 



armed with a long basal spine Leonidia Ckll. 



The new Hornia may be characterized as follows : 



Hornia gigantea n. sp. 



Color, head dark castaneous with irregular ferrugineous markings 

 on the frons and vertex, thorax black clouded with castaneous, scutel- 

 lum brownish black, elytra transparently ferrugineous the sutural mar- 

 gins slightly infuscate, abdomen with chitinous portions colored much 

 as head and thorax, legs black ; head broadly triangular, back and 

 sides with black pubescence ; labrum transverse, somewhat excavated 

 on its upper surface, apically broadly rounded, the free edge thickly 

 fringed with short golden hairs a few of which are paler and subsetac- 

 eous, the lateral margins slightly raised, the punctuation finer and 

 thicker towards the center; clypcus transverse, anterior border almost 

 straight, sides and posterior border somewhat convex, punctuation 

 rather stronger and more irregular than that of labrum; mandibles 

 black, robust, rather sharply truncate ; labial palpi with last article longer 

 than the other two and fusiform, the extreme apex knobbed; maxillary 

 palfii with first article minute, second very long, obconical, third shorter, 

 also obconical, the last rather shorter than preceding, fusiform (slight- 

 ly obconical) apex broadly and roundly truncate; antennae submonili- 

 form, first article shortly subglobose, second similar but smaller, third 

 to tenth gradually becoming more cylindrical and slenderer, last article 

 slightly loneer, apically narrowed and truncate, the joint between the 

 tenth and eleventh articles indistinct; eyes small; neck distinct, head 

 and thorax not closely joined; pronohim convex, almost subglobose, 

 narrowed in front and behind, posterior margin everted, pubescence 

 black and most abundant at sides; scuteUum transverse, roundly tri- 

 angular, with a few deep punctures; elytra irregularly and roundly 

 triangular, ora somewhat raised but not prominent, surface irregular- 

 ly rugose, with a few erect black hairs; abdomen large, as in Meloe 

 L., membranous, nine dorsal and seven ventral chitinous plates obvi- 

 ously visible; legs with femora robust, sparsely pubescent, tibiae more 

 strongly pubescent ; tarsi small, claws slender. 



Sexual characters : $ , the punctuation of the head is sparse, fine 

 and deep, the antennae reach to the middle of the elytra (5.5 mm. in
