interrupted at the suture. Scutellum, underside, and legs entirely red. The abdominal 

 and metasternal lines distinct, but very fine. ** 



This insect has caused me some perplexity, for although it is apparently allied to 

 M. guatemalce, it is slightly different structurally. It does not, however, differ so much 

 from the form of the M.pecari group as to leave much doubt that it will be best placed 

 there. The mentum is, roughly speaking, " rounded," and the maxillary palpi have the 

 apical joint lunate and wide. 



The antennae have the basal three, and sometimes the fourth and fifth, joints red. 

 Five specimens.

25. Iffycotretus tibialis. 



Saturate fulvus, elytris flavis, singulis maculis septum duabus baseos, duabus ante medium fasciam. quasi 

 praebentibus, duabus pone medium obliquis, et lunula ante apicem, nigris; antennis (articulis duobus 

 primis praetermissis), tibiis tarsisque nigris. Long. 10 millim. 



Hah. Nicaragua, Chontales (Belt). 



In form and size this insect is similar to M. pecan ; and it might pass for one of the 

 numerous varieties of that species, but that the markings do not appear as though they 

 would ultimately form, or had been derived from, the ordinary pattern of fully- 

 coloured examples of M. pecari. The black tibiae and tarsi are also abnormal, though 

 perhaps not of much importance in this genus ; in the absence of connecting links it is 

 impossible to say whether this indicates specific difference or not. 



There is only one specimen. 



26. Mycotretus picto-piceus. 



Oblongus, parum ovatus, nitidus, piceus, antennis nigris, articulis duobus basi pedibusque dilute piceis, elytris 

 tenuiter punctato-striatis, interstitiis fere laevibus, basi singulis annulo duplici flavo, humerum et maculam 

 juxta scutellum includente. Long. 7| millim. 



Eab. Panama, Bugaba (Champion). 



This is a species with a puzzling aspect ; it is of the form of M. ornatus and its 

 allies, but by the rather strongly widened palpi should come later on in the genus. 

 M. picto-piceus is of a nearly uniform pitchy-brown colour above, with the legs and 

 base of the antennae and underside rusty-red. The head is paler than the thorax, the 

 punctuation of both being very fine. The elytra are smooth, with fine punctured 

 striae ; the margin and some indistinct indications of a narrow wavy fascia near the 

 apical third are paler than the ground-colour ; two detached spots near the base of 

 each elytron are surrounded by a luteous line, which is prolonged backwards along the 

 margin. The underside is very smooth. 



A single specimen.
