50 EKOTYLULE. 



7. Mycotretus interstictus. 



Oblongo-ovatus, fulvus, antennis (basi excepta), verticis puncto, prothoracis punetis sex, scutello elytrorumque 

 fasciis duabus, e lineolis tribus interstitialibus interruptis, nigris ; elytris flavis, leviter punctato-striatis. 

 Long. 6 millim. 



Hab. Nicaragua, Chontales (Belt). 



Head and thorax very finely and closely punctured, shining ; the former with a black 

 dot on the crown, and a punctiform depression behind the dot ; the latter with six 

 black spots arranged four in a square with one on each side, the two basal spots well 

 separated from the base. Elytra rather light yellow ; between the striae in the alternate 

 interstices are three black lines interrupted by a yellow fascia near the base, the lines 

 not reaching the base nor the apex ; the two internal posterior lines are the longest, 

 but do not come nearer than one quarter of the elytral length of the apex ; posteriorly 

 there is a minute indication of a fourth line near the margin ; the extreme limb and 

 inner edge of the epipleurae are black. 



Underneath the body is entirely of a clear fulvous-red, with the legs a little paler. 

 Neither the metasternum nor its episterna are punctured. 



The antennae are black, with the two basal joints red, the third joint faintly piceous; 

 the last-named joint is elongate, but not so long as the fourth and fifth joints together. 



A single specimen. 



8. Mycotretus geminus. {Tab. ill. fig. 10.) 



Oblongo-ovatus, fulvus, capite prothoraceque crebre subtiliter punctatis, hoc punetis sex nigris ; elytris punctato- 

 striatis, interstitiis subtilissime punctulatis, singulis maculis tribus prope basin (duabus interioribus 

 geminatis) et duabus paullo pone medium punctiformibus, antennis articulis quinque ultimis, nigris. 

 Long. 6-6^ millim. 



Hab. Panama, Bugaba, David (Champion). 



This appears to be a very distinct species, the three specimens which Mr. Champion 

 obtained being alike in markings and almost so in size. In one example from Bugaba 

 the two inner spots near the base of the elytra just touch each other. M. geminus has 

 some affinity with M. interstictus, but the colour of the whole insect is very different, 

 and there is no spot on the head. The example from David is of a somewhat clearer 

 and lighter colour and has only four joints at the apex of the antennae black. The 

 figure is taken from a specimen from Bugaba, 



9. Mycotretus sexpunctatus. (Tab. ill. fig. 12.) 



M. lepido similis, at verticis puncto et prothoracis punetis sex nigris distinctus. Oblongo-ovatus, laete flavus, 

 subtilissime punctatus ; antennis articulis quinque vel sex ultimis, capite puncto occipitali, prothorace 

 punetis sex, elytris macula baseos antice et postice indentata fasciaque lata pone medium marginem 

 haud attingente, nigris. Long. 6-6| millim. 



Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).
