and on each elytron there is a ronnd black spot close to 

 the suture, rather behind the middle. The segments of 

 the abdomen are narrowly bordered with yellow. 

 Hab. — Oaxaca, S. Mexico. 



This may prove to be a distinct species from C. distin- 

 guendus, as the head appears rather longer. 



Chauliognathus axillaris, Fischer. 



I have just made a careful examination of the type 

 specimen of Cantharis Jlavipcs, Fabr. (Spec. Ins. 1781, 

 I. p. 259), in the Banksian collection at the British 

 Museum, and said to come from China. I find it to be 

 identical with a common Brazilian Chauliognathus, a dark 

 form of that described by Fischer (Mem. Mosc. 1823, 

 VI. p. 254), as Telephorus axillaris. 



The following remarkable species is allied to the fore- 

 going :— 



Chauliognathus expansus, sp. n. 



Fusco-niger ; capite opaco, clypeo ochraceo notato ; 

 thorace opaco, longitudine | latiori, anguste flavo-cincto, 

 lateribus leviter rotundatis parum reflexis ; elytris basi 

 thorace paulo angustioribus, medio duplo latioribus dein 

 ad apicem angustatis, depressis, flavis, dimidio apicali 

 fusco-nigro, mai'ginibus angustissime flavis, apice ipso 

 flavo acute dentiformi, lateribus medio plaga sub-vitrea 

 notatis ; coxis, femoribus tibiisque posticis ochraceis, 

 nigronotatis. 



Long. 7 lin. ; lat. elytr. med. 4| lin. 



This species is remarkable on account of the flat lozenge- 

 shaped elytra, which are in the middle rather more than 

 twice as broad as at the base, and on account of the semi- 

 transparent patch on the lateral margin, their surface is 

 rather closely punctured, and toAvards the apex are some 

 minute tubercles intermixed ; the pitchy-black patch occu- 

 pying the apical half of the elytra leaves the extreme mar- 

 gins and apex yellow and emits a slender branch which 

 runs along the side, between the vitreous spot and the 

 margin. Each elytron terminates in an acute spur.
