 Mandibular robustae, subtus concavae et excavatae, supra rotun- 

 datae, apice acutae, intus sine dente. Maxillae parvae. Palpi 

 breves et robusti : articulus ultimus palporum maxillarium 

 ovato-cylindricus et truncatus ; palporum labialium grandis, 

 crassus et late securiformis. Mentuin breve, transversum, 

 profunde excavatum et fortiter einarginatum, cum dente 

 medio simplici et malis acutis, lateribus rotundatis, extus 

 valde alveato. Ligula curta et angusta, truncata. Paraglossae 

 nullae. Antennae breves, moniliformes, articulis apicalibus 

 velutinis, compressis et dilatatis versus apicem, singulis 

 spatio sat lato laevi et nitido et supra et subtus relicto. Pro- 

 thorax subquadratus, parum subcordatus, capite multo latior, 

 postice quam antice parum angustior et longitudinaliter bi- 

 foveolatus; basi medio leviter transverse productus. Pro- 

 sternum sat latum et retro paulo projiciens. Scutellum 

 parvum. Elytra elongata, parallela, striata, sat convexa, 

 apice abrupte declivia et leviter emarginata, haud trun- 

 cata. Pedes mediocres. Tibiae anticae dilatatae, subtus exca- 

 vatae, intus emarginatae. Tarsi breves, transversi, fere monili- 

 formes, antici breviores ; in fcemina, et supra et subtus nitidi 

 et politi, sine setis vel squamis, ciliis ad marginem anteriorem 

 singulorum adstrictis exceptis; in mari, antici setis longis 

 instructi, ceteris ut in fcemina*; unguiculi simplices. Abdo- 

 men segmentis quinque, quorum primum et secundum con- 

 glutinata sunt. 



1. St. Whitei, mihi. PL XVII. fig. 6. 



Nigrum, politum, nitidum; capite foveis quatuor et lineis tribus 

 fronte impressis, quadrangulariter positis ; thorace elytris 

 angustiore, postice longitudinaliter bifoveolato, angulis posti- 

 cis rectis, elytris striatis, striis leviter punctatis, interstitiis 

 impunctatis planis. 



Long. 6 lin., lat. 2±- lin. 



Black, polished and shining. Head smooth and polished, and 

 rather convex ; mandibles hollowed out below, and having some 

 resemblance to the beak of a hawk ; antennae short, robust, com- 

 pressed and dilated towards the apex; first three joints smooth, 

 with one or two large punctures on the first and second, the 

 rest dull pubescent, with a broad, flat, polished line running up 



* I make this statement only from the examination of a male specimen 

 of St. Whitei and a female of St. solidum, these being all which have come 

 into my hands. But I have no doubt it is correct, as I find a similar dif- 

 ference in structure in the other Morionidce.
