EMPHYTUS.— HTLOTOMA. 35 



EMPHYTUS. 



Tenthredo, Fam. ix. (Emphytus, p.), Klug, Berl. Mag. viii. p. 278 (1819). 

 Emphytus, Sect, i., Hartig, Blattw. p. 247 (1837). 



Forty-six Palaearctic species of this genus are known, mostly from Europe; but 

 species are also known from Asia Minor, Algeria, Persia, and Japan. Seven species 

 have been recorded from North America, where the genus is less numerously repre- 

 sented than Harpiphorus, which differs from it only in having a median cellule in the 

 posterior wings. This is the first record of the genus in the Neotropical Eegion. 



1. Emphytus champion! (Tab. II. fig. 13, $.) 



Niger, longus, nitidus, tegulis pronotoque albis ; abdomine pedibusque luteis ; tarsis posticis tibiarumque apice 



fuscis ; alis subfumatis, costa et stigmate nigris. 

 Long. 8 millim. 



Hab. Guatemala, Purula {Champion). 



Head faintly punctured, frontal area indistinct, clypeus truncated at the apex. 

 Antennae a little longer than the abdomen, finely pilose, third joint longer than the 

 fourth. The transverse radial nervure is interstitial ; the transverse median is received 

 a little beyond the middle of the cellule. Claws simple. Sheath of the saw black. 



Very similar to the European E. serotinus, Kl. ; but that is broader and stouter, the 

 pronotum is quite black, the third and fourth joints of antennae subequal, &c. 



2. Emphytus mexicanus. 



Niger, genibus, tegulis tibiisque anticis sordide albidis ; alis fuscis. 

 Long. 8 millim. 



Hob. Mexico (de Saussure). 



The transverse radial nervure is received in the apical third of the second cubital 

 cellule, the transverse median in the middle ; the head is slightly rugose, clypeus 

 shortly incised. The antennae are shortly pilose, the third joint longer than the 

 fourth ; the blotch is broad and white. There seems to be a pale line on the pro 

 notum ; but it is not very distinct. 



This species is quite identical in coloration with the European Emphytus tener, Fall. 



Subfam. HYLOTOMINA. 



HYLOTOMA. 



Hylotoma, Latreille, Hist. Nat. iii. p. 302 (1802). , 



Arge, Schrank, Fauna Boica, ii. pt. 2, p. 226 (1802) . 



This is a very extensive and widely distributed genus. Forty-four Palaearctic species 

 are known, eleven from the East Indies, fifteen from the Ethiopian Region, twenty 

 from America north of Mexico, and twenty from South America.
