furrows distinct; there is also a sternal furrow. Meta- 

 notum irregularly areolated. There are 3 basal cel- 

 lules in the liind wings; they become successively 

 shorter and wider; the radius and cubitus are very 

 faint, almost obsolete; there is a stigma or, at any 

 rate, a thickening at the end of the costal nervure. 

 Cl3rpeus separated from the face; the apex furrowed 

 behind, transverse. The antennae are longer than the 

 body, slender. There is a distinct malar space, fully 

 two-thirds of the length of the eyes. OcelU in a 

 curve. Abdominal petiole as long as the following 

 2 segments united, its apical two-thirds dilated; the 

 spiracles are placed not far from the base of the 

 apical third. The 1st abscissa of radius not much 

 shorter than the 2nd. 



This genus fits in best into the Meteorinae, but the 

 abdominal petiole is more dilated at the apex; in 

 Meteorus the pterostigma is longer and narrower, the 

 2nd abscissa of the cubitus is much longer, being 

 almost as long as the 3rd, while in Pachytecus both 

 united are hardly one fourth of the length of the 3rd ; 

 the form of the sheath of the ovipositor readily sepa- 

 rates the two, it being in Meteorus long and slender, 

 of the normal form. Not short and thick. 

 Pachythecus ruficeps, sf. nov. 



Black shining, the head red, the antennae, palpi, 

 tegulae and legs palUd yellow, the f)rothorax yellow, 

 slightly tinged with rufous, the ventral surface and 

 the ovipositor testaceous; wings hyaline, iridescent, 

 the stigma and nervures fuscous, the base of the stigma 

 broadly white. $. 



Length 5 mm. 



Head and thorax densely covered with short white 

 pubescence. Scutellum tinged with testaceous. There 

 is a longitudinal furrow on the apical haK of the side 

 lobes of mesonotum. There are 3 areae on the base 

 of the metanotum, the outer large, with the apex 

 narrowed obliquely to a point. Mesopleural furrow 

 wide, crenulated. Post-petiole rather strongly stria- 

 ted, the striae clearly separated. 



Pachythecus testaceus, sp. n. 



Rufo-testaceous, the post-petiole for the greater 

 part and the hind legs, except at the base, black, 

 wings hyaUne, the stigma and nervures fuscous, 

 the basal nervures paler than the others. Eyes large, 

 greenish. Head, body and legs covered -^vith short, 

 pale pubescence. $. 



Length 4 mm. 



The eyes distinctly converge below; the malar 

 space is small. Head finely, closely punctured. Meso- 

 notum from shortly beyond the middle rather strongly 

 longitudinally reticulated; the fiu-rows striated, the 

 striae extending beyond them, but weaker there. 

 Metanotum irregularly areolated at the base, the 

 areae spreading out laterally; the areola of equal 

 ■width, longer than wide, the apical slope with a large 

 central, transverselj^ striated area and a smaller 

 irregular lateral one. Metapleurae more stronglj- punc- 

 tured than the mesopleurae, the top mth 2 or 3 irre- 

 gular obhque keels. Base of 1st abdommal segment 

 smooth, the rest longitudinally striated, the striae 

 becoming stronger towards the apex. 



Pachythecus albo-balteatus, sp. n. 



Rufo-testaceous, the antennae, abdomen and liind 

 legs black, the sides and apex of the 1st abdominal 

 segment, the base of the 2nd narrowly, and of the 

 following 3 segments more broadly above and below 

 and the basal 2 ventral segments, white. Face and 

 metathorax densely covered with longish white pu- 

 bescence; the hair on the rest shorter; on the hind 

 legs it is denser and blackish. Antennae almost twice 

 the length of the body, close on 60-jointed, covered 

 mth a short dense pile ,^. 



Length 6 mm. 



Head wider than the thorax; the face strongly 

 punctured. Metanotum closely, deeply reticulated, 

 the reticulations deep, small, the central more longi- 

 tudinal than transverse; the central apical part 

 bordered by stout longitudinal keels. 



Stirobracon ruficornis, sp. n. 



Black, densely covered with short white pubescence, 

 the head and antemiae red, the palpi and legs pallid 

 yellow, the base of the hind coxae blackish, wdngs 

 hyahne, iridescent, the costa, basal nervures and 

 stigma in front black, the rest black; basal abscissa 

 of radius one half of the length of the 2nd. Abdomen 

 closely longitudinally punctured, the base of the 1st 

 segment smooth, steeply sloped and margined all 

 round; the 2nd with a keel extending from Ihe base 

 to the apex, the base sHghtly triangularly dilated. 

 Parapsidal furrows distinct, reaching to the scutellar 

 furrow, converging towards the apex, the central 

 lobe of mesonotum being therefore triangular. Scu- 

 tellar dejjression crenulated. Front with a narrow, 

 but distinct furrow. The vertex behind and the 

 occiput are blackish. 



Lengtli 4 mm. 



The sjDecimen is probably a $, but the apical 

 segment of the abdomen is broken off. The species 

 may be known from 8. ruficeps, Cam. thus: 



Hind legs and antennae black, propleurae red, ab- 

 domen striated, parapsidal furrows indistinct, head en- 

 tirely red — — — — ruficeps Cam. 



Hind legs pale yellow, antennae rufous, propleurae black, 

 abdomen punctured, parapsidial furrows distinct, head 

 black behind. ruficornis. Cam.

Ein paniassiopliUes Insekt. 



Von Felix Brylc (Finnland). 



Am 20. März schlüpfte mir aus einer carelius- 

 Puppe (Juni 1911 verpuppt) eine ansehnhche Schlupf- 

 wespe, die die Herren Dr. Paul Schulze und 

 Embrik Strand als Exochilum circumfkxum L. 

 freundhchst bestimmten. Mein Exemplar hatte aus- 

 nahmsweise schwarze Schenkel. Hiernach wäre 

 endhch ein gefährlicher Schmarotzer, der unserem 

 Apollo und uns „schädhch" ist, festgestellt. „Ebenso 

 leiden die Parnassiusarten so gut wie gar nicht unter 

 Schmarotzern" (vgl. Paul Schulze: „Die Nacken-
