Diatrypa schvnkeif new species 



Figure 4,p 



Holotype: Male; Pucallpa, KIo Ucuyali, Peru, Mar. 9, 1948, 

 Schunke (USNM 62082). 



Male: A little larger than the preceding species. Head small, 

 flattened above, finely pubescent; frontal rostrum a little narrower 

 than the 1st antennal joint, strongly darkened. Face as long as 

 wide, yello^vish. Eyes feebly projecting cephalad; ocelli very small. 

 Antennae yellow with small brown rings. Palpi yellowish; 4th joint 

 of maxillary palpi a little shorter than 3d, 5th equaling the 3d, rather 

 strongly widening and obliquely truncated at apex. 



Pronotum rather strongly narrowing in front, with convex posterior 

 margin; disk feebly convex, uniformly testaceous, finely pubescent; 

 lateral lobes rather low, with feebly sinuated inferior margin, strongly 

 rounded angles. Genitalia rounded at apex (fig. 4,2>). 



Legs short, of the same color as the body, pubescent. Anterior 

 tibiae feebly dilated, perforated with two rather large, oval foramina. 

 Posterior femora rather thick, without any parallel apical part; 

 tibiae armed with four spines on each margin; superointernal apical 

 spur extending scarcely to the middle of the metatarsus; the latter is 

 rather long, armed above with four external denticles, one internal 

 denticle; apical spurs long, the internal extending nearly to the apex 

 of 3d joint. 



Elytra extending fairly beyond the apex of abdomen, narrowing 

 towards the apex; miiTor of the same shape as in allardi, but not so 

 transverse; six oblique veins, feebly curved, disposed rather regularly 

 along the archet; chords short, parallel, the first united to the mirror by 

 a small vein in the angle ; apical field rather long, with five veins and a 

 wide reticulation; lateral field wrapping; space between Sc and R 

 regularl}^ widening from the base nearly to the apex, crossed by 10 very 

 regularly distant veinlets; Sc bearing 11 branches. Wings a little 

 longer than the elytra. 



Length of body 14.5 mm.; length with wings 17.5 mm.; posterior 

 femur 8.0 mm.; elytra 12.2 mm. 



Remarks: Very close to allardi; larger with less transverse mirror, 

 apical field longer, space between the diagonal vein, the muTor and 

 the first chord a little wider.

Holotype: Female; Tingo Maria, Peril, Feb. 19, 1950, Allard 

 (USNM 62083). 



Female: Very small for the genus; blackish brown with a white
