species ; but, so far as can be seen without dissection, the palpi, 

 especially the maxillary pair, have their apical joint wider and more 

 triangular than in Symbiotes, in which they are oblong and truncate ; 

 but not at all securiform. 



1. Chondria lutea, u. sp. 



Breviter oblonga, lativscula, pallide ferruyinea iinicolor, jmbescens ; 

 prothorace transversa, lateriLus fortiter rotundatis, late margi- 

 natis, limbo crenulato, disco IcBvi, basi profunde bisulcata, elytris 

 leviter punctato-striatis. Long. 2^ millim. 



Hab. KiusHiu : Nagasaki. 



Tiie head is quite sunk in the thorax, of which the prominent 

 front angles, formed by the broad margin, completely surround it, 

 except in front ; the eyes are coarsely granulate. The antennae are 

 entirely red, their second to eighth joints short, the ninth and 

 tenth as broad as long and of the same form, the apical joint nearly 

 twice as long, compressed at the tip. Thorax twice as broad as 

 long (if the anterior angles are excluded), sides rounded and contracted 

 into the anterior prominent angles, the flattened margin broad and 

 slightly concave, the outer edge being a little reflexed and faintly 

 crenulate, basal sulci impressed as small fossae on the basal margin, 

 and thence continued as lines about halfway across the disk. 

 Elytra punctate-striate, the striae continued to the apex, but the 

 internal ones united before the apex. Pubescence rather thick and 

 pilose, of the same luteous colour as the whole insect. 



Two examples, found in haystack-refuse. 



Symbiotes, Redtenbacher. 



1. Symbiotes niponensis, Gorh. Ent. Mo. Mag. vol. x. p. 225. 



Hub. KiusHiu : Nagasaki. 



China : Kiu-kiang on the Yangtse-kiang river {Lewis). 



This curious little insect was met with commonly by Mr. Lewis 

 in the neighbourhood of Nagasaki, in haystack and other refuse : it 

 was also originally found by him in China ; but tiie latter locality 

 was omitted by oversight. 



2. Symbiotes? orbicularis, n. sp. 



Orbicularis, convexvs^fere hemisphcericus, cinereo-pilosus, brnnneus ; 

 thorace brevi, basi profunde bisulcata ; elytris sat crebre fortius 

 punctatis, hand stria tis. Long. If millim. 



Hab. Main Island : Kashiwagi, Kurigahara. 



Larger and moie orbiculate than S. niponensis and, moreover,- at 

 once to be distinguished from it by the punctuation of the elytra, 

 which is not in striae, but dispersed. The whole insect is rusty red ; 

 the antennae are formed as in S. niponensis, the two basal (especially 

 the first) joints being stout, the intermediate ones very s-mall and 

 linear, gradually shortening from the third (the longest) to the 

 seventh, which is quadrate. The three apical joints are subequal, 

 uearly quadrate, forming an elongate, stout club. The head and
