494 Mr. D. Sharp's descriptions of new genera 



its structure appears to be very mucli that of Ti/clnis, but 

 it is distinguished therefrom by the elongate intermediate 

 trochanters, by the double unguiculi, and by the last joint 

 of the maxillary palpi, which though elongate is not secu- 

 riform. The genus also rather closely approaches Bytliin us, 

 and indicates in an incontrovertible manner that tlie posi- 

 tion of that genus is near 7^t/chns. Tyrus jmlpalis and 

 Tyrus subulatus. King, must be referred to tlie genus 

 Gcrallus ; and for the present also Tyrus formosus. 

 King, should be located in the genus, though this latter 

 species is apparently almost as much allied to the Durhos 

 priscus. Bryaxis protcrvus, from Japan, appears greatly 

 to approach Gerallus in its general structure, so that the 

 affinities of the genus arc complex. 



Gerallus nanus, n. sp. Dilute brunneus, capite ol:)SO- 

 lete punctato, inter oculos foveis duabus parvis ; thorace 

 basin versus angustato, simplice, vix punctato : elytris sat 

 crebre fortiter punctatis, stria suturali, impressioneque sat 

 elongata intra-humerali. Long. corp. 1^ mm. 



]\Ias, femoribus intermediis margine anteriore medio 

 emarginato ; abdomine segmentis ventralibus brevissimis. 



Fem., femoribus intermediis simplicibus, abdomine seg- 

 mentis ventralibus brevibus. 



Maxillary palpi not much shorter than the antennae ; 

 2nd joint Avith a slender long stalk, its apical portion 

 dilated, oval ; 3rd joint oval, but Avith a short slender basal 

 stalk ; 4th joint fusiform. Antennje longer than head and 

 thorax; the joints 1 — 8 rather slender; 9tli joint con- 

 siderably larger and broader than its predecessor; 10th 

 slightly broader, and about as long as 9th; 11th joint 

 stout, as long as the two preceding ones together, pointed 

 at the extremity. Head much narrower than the thorax, 

 with the frontal tubercles short, and distinctly but not 

 widely separated, the part in fi-ont of the insertion of an- 

 tennce rather elongate and deflexed ; on each side near the 

 eye is a very small fovea. Thorax convex, small, only 

 about half as broad as the elytra, not so long as broad, 

 much narrowed behind, AA-ithout foveas or impressions, and 

 scarcely visibly punctured. Elytra much longer than the 

 thorax, distinctly narrowed at the shoulders, coarsely and 

 moderately closely punctured, each with a fine sutural 

 stria, and a broader impression at the base between this 

 and the shoulder. Legs long and slender.
