22. Mycotretus guatemalsB. 



Mycotretus Guatemala, Crotch, Cist. Ent. i. p. 441 \ 

 Hob. Guatemala 1 . 



Very nearly allied to M. psittacus. 

 Unique in the late Mr. Crotch's collection. 



23. Mycotretus pecari. (M.peccari, Tab. III. figg. 18, 19.)

Hab. Nicaeagua, Chontales (Belt, Janson) ; Panama, Bugaba (Champion). — South 

 Ameeica, Colombia 1 . 



This is a very variable species, so far as the extension of the fasciae on the elytra is 

 concerned, otherwise I should have been inclined to think that our insect from Panama 

 was distinct. The two specimens we have received from Nicaragua are even more 

 divergent in pattern and smaller ; but one example from Bugaba is intermediate, and I 

 have little doubt but that all these are only forms of one species. It is probable that 

 M. 14:-guttatus, Lac, is also only another variety. The constant points are the fuscous 

 tarsi, and black antennae with two basal joints red ; and that the black elytral spots 

 tend to form three fascia?, which at last become confluent. When the two basal fascia? 

 only are confluent we have var. a of Lacordaire ; when the three basal yellow fasciae 

 are complete it is var. b of Lacordaire. The single specimen of M. pecari in the 

 Cambridge collection has the black more extended, and occupying the whole apex ; 

 and M. lk-guttatus seems only to differ from it in having the whitish fasciae reduced 

 to seven roundish spots on each elytron. 



The specimens figured are (fig. 18) a specimen from Bugaba; (fig. 19) an extreme 

 variety from Chontales. 



24. Mycotretus elegans. (Tab. IV. fig. 3.) 



Oblongus, antice posticeque rotundatus, parum convexus, saturate rufo-ferrugineus, subnitidus ; elytris nigris, 

 macula transversa basali, puncto subhumerali fasciisque duabus ad suturam anguste interruptis (una 

 mediana altera subapicali), flavis ; antennis nigris, articulis tribus basi runs. Long. 9 millim. 



Hab. Guatemala, San Geronimo (Champion). 



Head and thorax very finely punctured, red ; the latter often suffused with some 

 indistinct cloudy markings, which show a tendency to represent some of the spots in 

 other species. Elytra finely punctate-striate, black, with three narrow yellow fasciae — 

 the first interrupted by the humerus, and consisting of a dot on the margin, and a 

 narrow transverse band on the base reaching the scutellum, but leaving a small black 

 spot on the base next to it ; the second in the middle, widest on the margin, and a little 

 oblique ; and the third near the apex, and slightly arcuate ; all three are very narrowly
