148 On a new Genus of Heteromerous Coleoptera. 



ginate in the middle ; the labial palpi short, the apical joint 

 very large, one third longer than broad, subparallel (but nar- 

 rowed at the base), truncate at the apex. The inner lobe of 

 the maxilla? terminating in a very slender, acute hook, with a 

 broad fringe within ; the outer lobe slender, terminating with 

 curved stiff hairs ; the palpi stout, the penultimate joint sub- 

 quadrate, the apical joint about twice and a half as long 

 as broad, cylindrical, narrowed at the apex. Labium ex- 

 tremely short. Epistoma trapeziform, emarginate anteriorly ; 

 the ocular canthus not projecting laterally beyond the eyes. 

 Eyes moderately prominent, very coarsely granular. An- 

 tennaj nearly as long as the head ; the two basal joints not 

 visible from above ; the 3rd joint the narrowest, about as 

 long as broad ; the 4th, 5th, and 6th joints transverse, each a 

 trifle broader than the preceding ; the 7th joint distinctly 

 larger than the 6th ; the 8th the largest (still transverse) , 

 the 9th and 10th a little narrower than the 8th ; the 11th still 

 narrower, somewhat flattened, obliquely truncate at its apex. 

 The rest as in Tribolium. 



Latheticus oryzce, n. sp. 



Parallelus, depressus, nitidus, piceo-flavus, thorace sat crebre evi- 



denter punctato, elytris irregulariter punctato-striatis. 

 Long. 2|-2| millim. 



General form of Tribolium f err ugineum, F., but rather nar- 

 rower, and with the head relatively larger and broader and 

 more square in general outline. Forehead and middle of the 

 epistoma gently convex ; the former not very thickly but very 

 distinctly punctured ; the epistoma less distinctly punctured, 

 about twice as broad as long, obliquely (but not much) nar- 

 rowed anteriorly, declivous in front, impressed at the sides, 

 emarginate in front; the ocular canthus not much encroach- 

 ing upon the eyes. Antennas rather short, thickest at the 

 eighth joint, so that their general outline is somewhat fusi- 

 form. Thorax very little broader than the head across the 

 eyes, a little narrower behind ; very distinctly but not very 

 thickly punctured ; the angles obtuse ; the sides somewhat 

 straight, very finely margined. Elytra as wide as the broadest 

 part of the thorax, parallel, their surface somewhat uneven or 

 wrinkled ; each elytron with four or five scarcely impressed 

 lines, with somewhat large punctures, the lines somewhat 

 irregular, or here and there interrupted. Legs rather slender. 



Hab. Calcutta, " in rice" (Brit. Mus.); Arabia (F. Bates). 



Mr. A. Fitch has shown me specimens of this species found 

 in England. Mr. G. C. Champion has examples found in 

 rice ; but I do not know where they came from.
