440 (G4) Mr. G. K. Crotch's Revision of 



Lacordaire's description does not entirely agree witli tlie type ; 

 the scutellum is red, and the 7th elytral spot nowhere reaches the 

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



Yar. 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. 



Mycotrelus 2)6cari, Lac. Erot. 167. 

 Columbia. 



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

 evidently very nearly allied to M. li-gitttatus. 



Mycotretus sedecimguttatus. 



Tschyrus l6-guttatus, Guer. Icon. R. A. Ins. 310 (1846), 



N. Granada. 



Interstitial punctuation very fine. 



Mycotretus scalaris. 



Mycotretus sccdaris, Lac. Erot. 168. 



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 Isevis; elytris albidis, 

 sutura tenuissime, fasciisque 4 communibus nigris ; 1 basali (in 

 maculas 2 fracta, 1 humerali, 1 juxta-scutellari) ; 1 ante medium, 

 prope mai'ginem fracta, ad suturam dilatata; 1 pone medium, 

 subrecta, prope marginem fracta ; 1 utrinque abbreviata, lata, 

 subapicali. L. 5 lin. 



Mexico (Salle). 



The last fascia is rather an oblong black spot. 



Mycotretus psittacus. 



Mycotretus 2^sittacus, Lac. Erot. 167. 



Mexico. 



My specimen agrees precisely with the description, but is 

 labelled " Bahia." lutei'stitial punctuation very faint. Coloration 

 of CaUischyrus amcenus.
