can judge from the parts in situ, the menturn is subtriangular and 

 the labium obcordate. 



Emydodes collaris. (PI. III. fig. 3.) 



E. nigra, setoso-hirsuta ; capite prothoraceque luteis. 

 Hah. Brazil (Para). 



Black, covered with short stiff hairs ; head dull reddish-yellow ; 

 prothorax thickly punctured, clear reddish-yellow; elytra coarsely 

 punctured, each in ten rows ; tibiae with long stiff hairs. Length 3 

 lines. 



Iodema [Cantharidae]. 



Head shortly triangular. Eyes round, prominent, entire. Labrum small, 

 rounded anteriorly. Palpi slender; terminal joint of the labial ovate, 

 of the maxillary subcylindrical. Antenna? short, linear, the joints 

 slightly obconic. Prothorax transverse, narrowed in front. Elytra 

 subdepressed, wider behind ; the sides somewhat concave. Legs slen- 

 der; tibia? bicalcarate; penultimate joints of all the tarsi small, tri- 

 angular. 



Differs from Cantharis, with which only it is likely to be con- 

 founded, in the short penultimate joint of its tarsi : the claws appear 

 to be undivided, from the close application of their two divisions. 



Iodema Clarkii. (PI. III. fig. 1.) 

 I. atra, nitida; elytris violaceis; tarsorum posticorum articulo primo 



albido. 

 Hab. Brazil (Organ Mountains). 



Head and prothorax deep glossy black, sparingly punctured, especially 

 the latter; scutellum narrowly triangular; elytra dark violet-blue, 

 thickly and irregularly punctured ; body beneath and eyes black ; base 

 of the first joint of the posterior tarsi whitish ; spurs of the middle 

 tibia?, and all the claws, except at their apices, yellow. Length 4 lines. 

 I am indebted for my specimen to the Rev. Hamlet Clark, who 

 took several individuals at Constancia, in the Organ Mountains. 



Zonitis [Cantharidae]. 



Fabricius, Syst. Entom. p. 126. 



Zonitis cyanipennis. (PI. III. fig. 5.) 



Z. angustus, glaber, ater ; prothorace, scutello, femoribusque (apice ex- 



cepta) luteis ; elytris cyaneis, nitidis. 

 Hab, Australia (Melbourne). 



Narrow, glabrous, shining ; head black, very narrow, and produced 

 anteriorly ; prothorax reddish-yellow, much longer than broad ; scu- 

 tellum dull yellowish ; elytra narrow, parallel, rather convex, dark
