ANNULOSA JAVANICA. 25 



Obs. This species, if not a variety of a Bengal insect described by Wiedemann under the 

 name of S.punctum, comes exceedingly near it. 



46. Indus. S. mandibulis substriatis, thoracc postice subtruncato, elytris lineato-striatis stria tertia bipunctata. 



Scarites indus Oliv. Ins. 2. no. 36. tab. 1. fig. 2.

 Insectum S. subterraneo Fab. affine, totum nigronitidum. Caput sulcis duobus rugosulis impressum. 

 Thorax lasvissimus marginatus, canali medio lineam anticam transversalem impressam attingente haud 

 ultra progrediente. Elytra marginata striis impressis ; stria a sutura tertia punctis duobus mediis 

 hoc apicem versus illo basin versus impressa. 



Obs. This species was confounded by Fabricius with his S. subterraneus, an American insect, 

 which would have been an Attelabus with Degeer. 



Fam. 5. BRACHINID^. 



In this family, as well as in the last, we have rarely, if ever, that dilatation of the tarsal joints, 

 which often marks in so extraordinary a manner the difference of sex among the Harpalidcc 

 and Carabidce. 



The typical insects of the family are gregarious, and well known for the detonating mode 

 ot defence which they employ against their enemies. This curious property results from the 

 rapid volatilization when exposed to the air of an acrid liquid analogous to that which we have 

 already noticed in the Carabidce, but which in the Carabidce retains its liquid state on being 

 ejected from the anus. The construction of the two sacs which gecrete this fluid is explained by 

 Cuvier in the Rkgne Animal. 



Each of the three first insects to be described in this family might have been assigned to new 

 subgenera, as they do not accurately coincide with Bonelli's characters for the genera Dromius, 

 Lamprias and Lebia; but as their place in the system is visible at first sight, I have judged it 

 unnecessary to multiply subgeneric names. 



Genus DROMIUS Bon. 



47. Tetbaspilotus. D. nitidus, capite nigro, thorace nigropiceo, elytris atris striatis : maculis duabusjlavis. 



Long. corp. vix ^ 

 Caput nigrum labro oblongo quadrato antennis palpisque piceis. Thorax obcordatus latior quam longus 

 depressiusculus canaliculars lateribus subreflexis, Elytra maculis duabus hac basali ilia posticali. 

 Corpus subtus pedesque picei. 



Obs. This species has the middle tooth of the mentum indistinct, and thus to a certain degree 

 leaves Dromius. Carabus notulatus, of Fabricius, appears to come near to our insect, which, 

 with the following species, has the elytra very little truncated, if at all. 



Genus LAMPRIAS Bon. 



48. Ruficeps. L. rufa nitida, elytris cyaneis striatis medio depressiusculis : striis profundioribus, oculis genicu- 



lisque nigris.

Obs. This species appears to be more common on the continent of India than in Java.
