pubescent, with, the veins thick and prominent, the costal margin 

 almost straight, a little curved at tip ; membrane wide, \^dth a large, 

 closed cell at the inner angle from which two veins run curving 

 towards the tip. 



Bathtdema socia, sp. nov. 



Eobust, blackish piceous, yellowish pubescent. Head tinged 

 with brown, not polished, punctate above and below ; antennae 

 closely pubescent, pale fulvous or piceo-testaceous, Avith the basal 

 joint darker above, aud the thick apical joint fuscous, the apex of 

 the second joint aud base of the third sometimes with a narrow 

 dark baud ; rostrum f ulvo-testaceous, hairy, piceous at base and 

 tip. Pronotutn dull blackish, coarsely punctate, the anterior lobe 

 interruptedly margined with yellow, the posterior lobe feebly sinu- 

 ated behind, with a testaceous arc next the humeri and a dot of 

 the same coloiu' on the middle of the margin, the lateral margin 

 pale castaneous behind ; pleurae dull piceous, punctate, pubescent, 

 bordered with pale castaneous. Coxae pale castaneous ; legs yellow, 

 tinged with fulvous. Scutellum dull fuscous, transversely convex 

 at base, obsoletely punctate, pubescent, compressed and testaceous 

 at tip. Corium and clavus testaceous, crossed in common by a 

 dark brown broad band at tip, which includes two short yellow 

 streaks and a dot ; membrane brownish, with a pale dot at tip, 

 Venter dull piceous. 



Length to tip of membrane 2 millim. ; width of base of pronotum 

 I millim. 



This interesting little insect approaches nearer to Peritreclms^ 

 Fieb., than to any other genus with which I am acquainted. But 

 the characters here given wiU, it seems to me, serve full well to 

 separate it from that genus. 



Four specimens were secured on the Soufriere volcano, in April, 

 distributed in the moss, at altitudes of 2000 and 3000 feet above 

 sea-level. 



SPHiEEOBixJS, gen. nov. 



Form similar to that of fferceus, Stal, but differs most conspicu- 

 ously in having the anterior lobe of pronotum globose and as wide 

 as the very short posterior lobe. The head is conico-ovoid, acute 

 at tip, the tylus projecting prominently in front of the clypeus, 

 with the two adjoining lobes of the cheeks short and feebly pro- 

 minent ; eyes placed on or below the line of the vertex; basal joint of 

 rostrum thick and shorter than the throat. Antennae moderately 

 long, gradually thickening towards the tip, the basal joint much 

 shorter than the head, the third joint a little shorter than the second, 

 the apical joint longest and much thicker than the third; the bucculae 

 short aud restricted to the tip. Collum of the pronotum wide below, 

 narrovi' above ; the anterior lobe of the pronotum fully as wide as 

 the very short, transverse posterior lobe, separated by a deep stric- 

 ture, coarsely punctate, with the posterior margin sinuated and 

 the humeral angles callous. Anterior femora very thick, fusiform,
