64 MYCOTRETUS. 



Lacorclaire's description does not entirely agree with tlie type ; 

 the seutelhini is red, and the 7th elytral s])ot nowhere reaches the 

 apex. The coxal lines are well marked, interstices almost smooth. 



Var. 1 conjunctus. Form and punctuation similar, the three 

 pairs of spots coalesce transversely, the 1st and 2nd pair being 

 further joined by a small longitudinal mark. 



Mycotretus pecari. 



Mycotreius 'pecari, Lac. Erot. 167. 

 Columbia. 



I have seen only the variety without the apical spot, it is 

 evidently very nearly allied to M. li-ynUatas. 



Mycotretus sedecimguttatus. 



Ischyrus \(d-(juttatus, Gutr. Icon. B. A. Ins. 310 (1840). 



N. Granada. 



Interstitial punctuation very fine. 



Mycotretus scalaris. 



Mycotretus scalaris, Lac. Erot. 108. 



Columbia. 



Interstices visibly punctate, metasternum at the sides more 

 strongly punctate. This is near M. conjunctus in markings, 

 except that in the type they are testaceous red, but this may be 

 the result of immaturity. 



Mycotretus illustris, sp, n. 



Oblongo-ovatus, sat latus, paulo depressus, testaceus, ubique 

 subtiliter parce punctulatus, subtus fere h\;vis ; elytris albidis,

Mexico (Salle). 



The last fascia is rather an oblong black spot. 



Mycotretus psittacus. 



jlli/cotretus 2)sittacns, Lac. Erot. Ku. 



Mexico. 



My s]iecimon agrees ]>recisely with the description, but is 

 labelled " Bahia." Interstitial punctuation very faint. Coloration 

 o^ CaUischyrus amrenus.
