Leiochrinus, Westw. 



Leiochrinus, Westwood, Tijdschr. voor Ent. xxvi. p. 68. 



The genus Leiochrinus was founded by Westwood in 1883, 

 and a figure of the type of the genus, L.fulvicollisj is given 

 on pi. iii. fig. 14, and on pi. v. fig. 7 is a drawing of the 

 posterior tarsus. The type of this genus evidently agrees 

 with L. satzumcej sp. n. ; the head is entirely concealed under 

 the thorax, the latter segment and the elytra forming an 

 almost complete circular outline. With the head thus 

 concealed the antennal orbits are absent. The form of the 

 tarsi, also, in the genus is most peculiar. Westwood gave a 

 drawing of the upperside of tlie type, and to supplement his 

 figure I give here a woodcut, fig. 2, showing in outline the 

 under surface of L. satzumce and the fore tarsus. There are 

 several genera in which the curious tarsi are, with more or 

 less modified forra^ similar, so that I quite agree with Mr. 

 Champion that it is best to group them together as Leio- 

 chrininse. I think the position of the group is near the 

 Diapering, as they cannot be far separated from the genus 

 Derispia^ which, I think, is placed in a natural position if it 

 is put near Diaperis. 



Leiochrinus satzumce, sp. n. (Woodcut^ fig. 2.) 



Circularis, rufo-testaceus, nitidus ; thorace disco trausversim infus- 

 cato ; elytris delicate punctulatis, disco rufo-testaceo, marginibus 

 angustissimis testaceis.

the tissue of the thorax is very thin and pellucid over the 

 eyes, which can be dimly seen through it. The thorax has a
