LANGURIIDAE 3f)7 



scribed six species, and in the " Biologia Cent. Amer. " I have 

 described nine more, they are very closely allied and difficult 

 of determination. 



11. Crotchia fusiformis, n. sp. 



Angustatttj nigro-subaenea , nitida; capite et protliorace parce 

 fortiter distimie punctatis, hoc subquadrato,, angulis anticis disiinctis 

 vix reftexis; elylris leviter punctato-strialis, anlennarum basi rufo- 

 picea. — Long. 5-8 millim. 



Mas, abdominis segmentis tribus intermediis puncto duplici seti- 

 gero munilis. 



Hab. Paraguay, Puerto 14 de Mayo (Boggiani). 



Head with rather prominent eyes, epistema wide and slightly 

 emarginate in front , rather more thickly punctured than the 

 crown of the head , the latter deeply sparsely and distinctly 

 punctate. Antennae rather long, the third to the sixth joints 

 fusiform and apparently longer than they are in C. parallela, 

 Fowler; one, two or three joints before the club are blackish, 

 the basal joints are red. The thorax is nearly square, the sides 

 margined by a thickened line, which (as in all the species I 

 have seen) is a double line ; the front angles are easily seen from 

 above , the base very finely margined with an indistinct puncti- 

 form fossa a quarter of the breadth from the hind angles ; 

 the elytra are elongate for this genus, with very fine series of 

 closely packed punctures; widest at the base, very gradually nar- 

 rowed to the apex. The brassy colour in this species is distinct, 

 but the whole insect, may be slightly piceous at times. It is very 

 close to C. parallela, and to C. verae-pacis , Gorh. It is larger 

 than my types of the former, less pitchy, less parallel, with 

 rather longer antennae. There are eight examples all from 

 Puerto 14 de Mayo. 



12. Crotchia balzanii, n. sp. 



Fusiformis, nigro-picea , nitida; capite parents sed dislincte , 

 prothorace minute punctatis, hoc transverse subquadrato, basi 

 utrinque foveolato; elytris in medio lalioribus, lenuissime punctato- 

 striutis , anlennarum basi, pedibusque rufo-piceis. — Long. b"
