116 MR. M. JACOBY ON THE [^^b. 1, 



Head impunctate, the frontal tubercles rather flattened ; palpi 

 slender ; antennse two thirds the length of the body, testaceous, the 

 apical joints obscure fuscous. Thorax about one half broader than 

 long, the sides strongly narrowed or constricted at the base, 

 obsoletely impressed at the sides, impunctate, the lateral margins 

 furnished with some long hairs. Scutellum broader than long, 

 testaceous or margined with piceous. Elytra clothed with some 

 rather long and stiff hairs, strongly longitudinally costate at the 

 sides, less strongly at the disk, the interstices impressed with two 

 rows of distinct punctures, partly confluent and becoming single 

 towards the apices. Underside testaceous, the breast sometimes 

 darker. Legs moderately long, the claw-joint of the posterior tarsi 

 very elongate, as long as the metatarsus. 



Priapina (gen. nov. Galerucinae). 



Narrowly oblong. Antennse filiform, the third joint very small. 

 Thorax transversely subquadrate, obsoletely grooved at the disk. 

 Elytra closely semipunctate-striate. Legs slender, tibiae with a 

 spine ; the metatarsus of the posterior tibiae longer than the three 

 following joints together ; claws appendiculate. 



I am obliged to establish this genus on account of the structure 

 of the antennae, in which the third joint of the male is so small as 

 to be scarcely perceptible ; the long nrst joint of the posterior tarsi 

 and the mucronate tibiae are further characters which will assist in 

 the recognition of Priapina. The specimen being glued to a card, 

 I am unfortunately not able to speak about the state of the anterior 

 coxal cavities. There will, however, be no difficulty in recognizing 

 the genus if the antennae are examined. In Luperodes, a closely 

 allied genus, the third joint in both sexes is very distinct, double the 

 length of the second and scarcely shorter than the fourth. 



Priapina longicornis, sp. nov. 



Fulvous or testaceous ; head impunctate ; terminal joints of the 

 antennae fuscous ; thorax fulvous, rugosely punctured ; elytra testa- 

 ceous, the margins narrowly piceous, surface closely punctured. 



iS . Antenna longer than the body, the third joint minute. 



$ . Antennae shghtly shorter, the third joint a little longer ; 

 elytra coarsely punctured. 



Length 1 line. 



cJ . Head impunctate, fulvous, the frontal tubercles narrowly trans- 

 verse ; eyes rather large. The four lower joints of the antennae 

 testaceous, the others fuscous, the fourth joint longer than the three 

 preceding ones together and longer than the following joints. Thorax 

 twice as broad as long, the sides slightly narrowed towards the base, 

 the angles not produced, the anterior and posterior margins straight ; 

 surface obsoletely transversely depressed, coarsely punctured. 

 Scutellum piceous. Elytra testaceous, narrowly margined with 

 pioeous, very closely punctured, the punctuation arranged in semi- 

 irregular rows. Legs rather long and slender. 



In the female the third joint of the antennae is nearly equal in
