330 COLEOPTERA. 



DesniogTainiiia reticulata nov. sp. 



Head and thorax dull bronzed green, the labrum and base of the 

 antennae rufescent, punctuation moderate and sparse, the thorax de- 

 pressed laterally, anterior angles finely refescent, scutel of the same 

 bronzed green, elytra bright shining rufous, moderately punctate stri- 

 ate, confused at the sides and behind, each with a common sutural 

 stripe narrowed behind, an elongate humeral spot, a transverse irre- 

 gular median band sometimes not attaining the suture and an elongate 

 irregular post median spot, greenish black, body beneath and legs 

 dark greenish black. Length 1\ mm. 



Two examples, Colombia, first Jacoby coll. 



The shape and size of rufofasciata Kirsch. The sides of 

 the thorax are nearly straight behind, moderately rounded 

 in front, the front angles not produced, the lateral fovea of 

 the thorax is vague and more median than usual : in one 

 specimen the humeral mark touches the median band, the 

 rear mark does the same, the effect being to make two large 

 basal rufous spots near the suture, another at and surround- 

 ing the humerus and two submedian (ill-defined behind), 

 side by side, specimens probably occur where the whole sur- 

 face is divided into rufous spots. It is the only red spotted 

 species known to me where the elytra are smooth polished. 



Desinograniiua santos nov. sp. 



Ovate parallel ; head dull alutaceous black with labrum and antennae 

 dull yellow, thorax the color of the head with a few scattered punc- 

 tures, especially noticeable at the sides which have a small well-marked 

 fovea, scutel dull black, elytra dull flavous finely striate punctate, ob- 

 solete behind with a common broad sutural vitta, a subbasal trans- 

 verse fascia, obsolete back of the shoulder, a similar sub-median fascia, 

 semi-obsolete near the suture and the apex broadly excepting the ex- 

 treme tip, all dull alutaceous black, below with legs shining black, 

 except that the transverse black bands are carried round and include 

 their proportionate share of the epipleurae. Length 8| mm. 



One example, Epirito Santo, Staud., '98, among unnamed 

 material of Jacoby collection. 



Somewhat resembles Metastyla nigrofasciata Stal. The 

 anterior angles of the thorax are much produced and together 

 with the whole lateral edge much thickened, the scutel and 

 immediately about it is semi-shining all the remainder of the 

 upper surface is dull, the black apical area bears a round 

 yellow spot at the apex ; the black bands do not have clear 

 cut edges, but rather the reverse.
