are fine ; and the punctures in the latter are more numerous, and not so large or deep. 

 The antennae are shorter, the third to the seventh joints especially shorter. The most 

 striking difference is, however, the strong punctuation of the underside, showing an 

 alliance to M. pygmceus ; but the palpi are less widened at the tip, and are, I think, 

 longer than in that insect ; the underside is also slightly pubescent. It is therefore a 

 rather abnormal species, and I think has some claim to affinity with Tritoma, the short 

 scutellar striae being indistinctly indicated. One specimen. 



47. Mycotretus cribratus. 



Oblongus, ovatulus, saturate sanguineus ; capite prothoraceque parce profunde punctatis ; elytris punctato- 

 striatis, striis fortiter profunde punctatis ; antennarum artieulis quinque ultimis nigris. Long. 3 millim.

Of the same size as M. miniatus, and with the head formed as in that and the allied 

 species ; the palpi very wide at their apex ; the antennae rather short and robust, their 

 third joint as long as the following two joints united. Thorax narrowing in front, the 

 base distinctly margined. Elytra with very large and distinct punctures in the striae, 

 especially in the external ones commencing from the fourth stria. Underside rather 

 strongly punctate ; the prosternum almost rugose in front. Metasternum smooth in 

 the middle ; the sides with large separate, the episterna with close, punctures, the 

 space between the latter finely alutaceous. A very considerable series of specimens of 

 this species was obtained by Mr. Champion at Bugaba ; single examples only occurred 

 at each of the Guatemalan localities. The Guatemalan specimens are apparently 

 referable to the same species ; but I regard the Bugaba examples as typical, it being 

 from them that the description is made. 



48. Mycotretus nigripes. 



Oblongus, parum ovatus, saturate sanguineus, pedibus,. tarsis exceptis, nigris ; capite prothoraceque parcius sat 

 fortiter punctatis ; elytris fortiter punctato-striatis, striis ad aj icem obliteratis. Long. 3 millim. 



Sab. Guatemala, Cerro Zunil (Champion). 



More parallel and less narrowed in front than M. miniatus. The head is punctured 

 as in well-developed examples of that species, viz. sparsely. The thorax is more 

 sparingly punctured than in any example of M. miniatus I have seen ; it is also of 

 nearly equal width before and behind, with the front angles more depressed, so that it 

 is more convex. The antennae are black, excepting the two basal joints ; their third 

 joint is not much longer than the second. The underside is more roughly punctured 

 than in M. miniatus, and is entirely clear red. The legs are black, with red tarsi. The 

 punctuation of the elytra is much stronger, and the punctures in the striae less 

 numerous than in M. miniatus. 



A single specimen.
