Paralaslor eu tret us, sp. n. 



Female black, the pronotum, tegiila3, two spots on the 

 scutL41uin posteriorly, most of the po^tscutellum, the tibite 

 and tarsi, the first abdominal segment (excepting its basal 

 declivous portion), an apical band on the second occupying 

 about the apical sixth of its length, as well as a medio- 

 frontal spot and a small one behind eacli eye red or ferru- 

 ginous. 



Clypeus very slightly emarginate, but the lateral teeth 

 subacute, rather evenly and largely punctured, the punctures 

 shallow. Pronotum truncate and evidently margined in 

 front. Head and thorax with short hairs, very closely, 

 evenly, subrugosely punctured. Wings subhyaline, dai-ker 

 along the costa. Basal abdominal segment extremely densely 

 punctured ; second coarsely, closely, and nearly evenly punc- 

 tured all over, narrow, long, subparallel-sided ; baneut'i, 

 behind the sulcature, well raised above the basal part, but 

 not extremely strongly so, and not at all produced in the 

 middle at the top of the truncation, there being no trace of a 

 prominent tubercle. Dorsally the second segment is strongly 

 convex longitudinally towards the base, bub not greatly 

 raised. 



This small narrow species may perhaps be best placed 

 next to P. despectus, P. It in many respects resembles 

 P. imitatoi' structurally, but the tegulae lack the very coarse 

 punctures, and over a large area they are smooth and 

 shining and almost without puncturation on this area. 



Length about 8 mm.

Obs. When describing P. dehilitatus I made the remark 

 that the unique example bore a MtSS. na{ne, A. pnsitlus, 

 Sauss. This was an error, it having been labelled A. pu~ 

 sillusculus by JSaussure without being desciibeJ.
