atyphus. 1 75 



Genus 30. ATYPHUS*. 



Palpi maxillares breves, dllatati, art. 3' 10 subquadrato. 



Palpi labiales minuti, art. ultimo elongato. 



Antennae fill 'formes, sat rolmstoe. (Jiaud tarn ut in Hydmosyne). 



Caput transversum, latum, verticale. 



Thorax transversus, rectangularis. 



Elytra parallela, subcylinclrica, ad apicem rotundata. 



Pedes : tibiis posticis calcaratis, tarsis brevibus. 



Labrum short, contracted, transverse. 



Mamillary palpi (Tab. VII. fig. 5 m) : the basal joint minute, 

 rectangular, quadrate ; the second longer than the first, dilated and 

 obliquely truncate at the apex ; the third much shorter and broader 

 than the second, almost quadrate ; the terminal joint broadly 

 conical. 



Labial palpi (Tab. VII. fig. 5ra) minute; the second joint dilated 

 and transversely truncate at the apex ; the terminal joint elongate, 

 and of half the breadth of the apex of the second. 



Antennas approximate, situated between the inner margins of the 

 eyes, filiform, tolerably robust (more slender, however, than in 

 Hydmosyne) ; the basal joint dilated (not so distinctly as in the pre- 

 ceding genus) ; the second short and ovate ; the third longer than 

 the first, and attenuated ; the fourth and fifth subequal. 



Eyes large, subglobose, lateral, at the base of the head, extending 

 laterally to nearly the anterior angles of the thorax. 



Head somewhat broad, transverse, and (when viewed laterally) 

 deflected at right angles to the elytra (not porrect and narrowed, as 

 in Hydmosyne). 



Thorax transverse, rectangular, slightly broader than the head ; 

 the sides marginate and obsoletely subsinuate. 



Scutellum smaller than in the preceding genus, triangular. 

 Elytra parallel, subcylindrical, perceptibly broader than the head, 

 rounded at the apex. 



Legs : the anterior femora and tibia} (when viewed from in front) 

 robust. The tarsi are short ; the two basal joints triangular (the 

 second being slightly shorter than the first) ; the penultimate joint 

 more transverse and bilobed ; these three are clothed on their inner 

 surface with a thick and short pubescence : the terminal claw is bifid 

 and simple, robust at the base. The posterior femora incrassated, at 

 the apex obliquely truncate. The tibice (Tab. VII. fig. 5 g) are in- 



* d, non ; rixpb), turgesco.
